[0002] [002] The present invention is directed to vibrating separators and mud screens; equipment and methods for detecting different parameters related to the use of separators and agitators, including, without limitation, fluid levels in such separators; and apparatus and methods for adjusting such levels and for adjusting the extent of the margin area of a sieve. BACKGROUND OF THE INVENTION
[0003] [003] In many prior art vibratory separators and mud screens, a puddle or mass of liquid or material is formed on top of one or more screens or sets of screens used to filter the material introduced into the separator or agitator. The depth of such a fluid or material can affect the efficient operation of the separator or agitator. Any fluid or material that is too deep may not be properly filtered. Materials and fluid that are too shallow may flow through the sieve too quickly or not enough weight to be properly filtered.
[0004] [004] Shale shakers help maintain certain desired properties for the drilling fluid, using vibrating screens to remove large particles, while allowing certain smaller particles to remain in the fluid. Such large unwanted particles can include debris and debris caught during the drilling process. Smaller particles may include drilling fluid additives required to maintain the desired density and viscosity for the drilling fluid. The screens of these agitators have a limited service life, and can be time and money consuming to replace. The agitator needs to be turned off and, preferably, rinsed before replacing the sieve.
[0005] [005] The good maintenance of the margin area is an important factor for the useful life of the sieve. The “margin” area is the distance from the interface between the dry part and the wet and fluid part of a last sieve to the end of the sieve. Thus, a zero margin extension describes an agitator operating with the drilling fluid covering the entire sieve area of the final sieve and flowing to the discharge. This can be expensive, due to the loss of the drilling fluid that falls out, instead of flowing through the sieve. An extension of 20 ”of margin, in certain agitators, indicates an agitator operating almost dry, with the last sections of the sieve potentially vibrating against completely dry particles. These dry particles vibrating at the edge of the last sieve can open holes in the sieve and shorten the life of the sieve. The extent of the margin is affected by variables, such as fluid flow rates and drilling fluid properties, including viscosity, density, temperature and solids content.
[0006] [006] In many prior art separators and agitators, tilt or elevation mechanisms are provided for horizontal adjustment of the angle of the sieve (s). For example, a prior art S stirrer (shown in Fig. 1) has a tilt mechanism that allows a basket containing a sieve to be tilted around a hinge point P up to 5, from the horizontal.
[0007] [007] US Patent 4,082,657 discloses a separator equipment that has assembly structures for individual height adjustment for each sieve unit, allowing adjustment of the angle of the sieve unit, in relation to the horizontal position.
[0008] [008] US Patent 6,575,304 B2 discloses hydraulic ram equipment under a sieve housing that is used to adjust the angle of inclination of the sieve housing.
[0009] [009] In many prior art systems, a determination of the level of material or fluid in a sieve or set of sieves of a separator or agitator is made visually, and then adjustments of the angle of inclination of the sieve or the angle of support of the sieve are made manually.
[0010] [010] There is a longstanding need, recognized by current inventors, to provide an efficient and accurate measurement of the depth of fluid or material in a sieve or set of sieves of a vibrating separator or shale shaker. There is a long-standing need, recognized by current inventors, for these separators and agitators, for a precise adjustment of said depth, based on the respective measurement. There is a long-standing need, recognized by current inventors, for a shale shaker or vibrating separator with adjustable depth of the sieve pool in order to adjust the extension of the margin of the last sieve, in order to improve efficiency and prolong the service life. the sieve. BRIEF SUMMARY OF THE INVENTION
[0011] [011] In some configurations, the invention provides a method of automatically controlling a vibrating separator that has at least one sieve for sifting materials and sieve holders removably attached to the sieve by means of an electromagnetic clamping device and motor device for sieve vibration, such a method comprising fixing the sieve holders to the sieve by energizing the electromagnetic clamping device to obtain a magnetized state and maintaining it in a magnetized state with a transient pulse signal and, by means of a second and later transient pulse signal adjusting the electromagnetic fixation device to a demagnetized state, releasing the sieve, while the fixer remains in the demagnetized state indefinitely, until it is energized again by another transient electrical pulse signal.
[0012] [012] In other configurations the invention provides a vibrating separator having: at least one sieve for sieving material; motor device for vibrating the sieve; sieve holders removably attached to the sieve; magnetic fixture for fixing the sieve holders to the sieve, the fixing device being configured to change from the fixation state to the state released by flow cancellation or by changing from a first state where the magnetic flow walks outside the fixation apparatus and a second state in which the magnetic flux circulates within the fixation apparatus and where the flow that walks outside the apparatus is reduced or eliminated.
[0013] [013] The fixture may comprise a multitude of magnetic fasteners, such as electromagnetic fasteners arranged at spaced intervals along the edge of the sieve.
[0014] [014] In addition, the vibrating separator may also comprise a 'G' force controller configured to ensure that vibratory accelerations are kept within the limits of the electromagnetic clamping apparatus.
[0015] [015] In some configurations, the magnetic fasteners may be of the serial or parallel type and comprise at least a first magnet or group of magnets having a first magnetic direction, and at least a second magnet or group of magnets capable of switching between one first state, where the magnetic directions of the first and second magnets or groups of magnets are aligned or opposite, the magnetic flux travels out of the fixture and the fixer is energized, and a second state where the magnetic directions of the first and second magnets are opposite or aligned (that is, changed from their relative directions in the first state), the flow circulates locally within the fixture and the sieve is released.
[0016] [016] The first and second magnets or groups of magnets may be permanent and mechanical means may be provided for switching between states. Actuators may be provided for switching between states, such as by relative rotation of the magnet or magnets in a group.
[0017] [017] In other configurations, magnetic fasteners can be based on electropermanent magnets capable of being electromagnetically switched between fixing and releasing states and can be monostable or bistable, the latter type having the benefit of not needing current, except during switching between states.
[0018] [018] In some configurations the fixation device can be based on monostable electropermanent magnets that, in some configurations, will use permanent magnets of high coercivity and coils to produce the switching between the fixation and release states, such as, for example , due to flow cancellation or flow deviation. With monostable magnets, the fixture will have a normal screen fixation state in which it will remain indefinitely, but it can be temporarily switched to the screen release state by energizing one or more transient electrical pulses, with the device returning to the state of sieve fixation when the pulse or pulses are interrupted. The high coerciveness of the permanent magnets prevents them from being demagnetized by energizing the coils.
[0019] [019] In other configurations, each fixer may comprise a bistable electropermanent magnet that may be of the serial or parallel type. For example, in some parallel configurations, electropermanent magnets may comprise at least a first magnet or group of magnets having a first magnetic direction and at least a second magnet or group of magnets capable of being electrically switched between a first state, where the directions magnets of the first and second magnets or groups of magnets are the same, the magnetic flux walks outside the fixture and the fixer is energized, and a second state where the magnetic directions of the first and second magnets are opposite, the flux circulates locally inside the fixture and the sieve is released. In other serial configurations, electropermanent magnets may comprise at least a first magnet or group of magnets having a first magnetic direction and at least a second magnet or group of magnets capable of being electrically switched between a first state, where the magnetic directions of the first and second magnets or groups of magnets are the same, magnetic flux substantially circulates inside the fixture and the fixer is released, and a second state where the magnetic directions of the first and second magnets or groups of magnets are opposite, the flow moves through out of the fixture and the fixer is energized.
[0020] [020] The magnets may be electropermanent magnets, where the magnetization of one of the magnets or groups of magnets has states switched by transient current pulses. For this purpose, the magnet or magnets of one of the groups may be of relatively high coercivity, the magnet or magnets of the other group may be of relatively low coercivity and the residual induction of the magnet or magnets of the first and second groups to be approximately the same. Such an electropermanent magnet may, in this way, be a device in solid state, which allows an external magnetic field to be modulated by electrical pulses. No electrical force is required to maintain the field, but only to change the state of the fixing devices. Electropermanent magnets may contain two magnetic materials, one magnetically hard (such as Nd-Fe-B) and one semi-hard (such as Alnico).
[0021] [021] The present invention, in certain configurations, provides a shale shaker or vibrating separator with a base; a basket movably mounted on the base and to support the sieve apparatus, for treatment of material introduced by a first end of the basket in the vibrating separator, with the basket on a base and the first end articulating with respect to this base, the basket having a second end away from the first end, with the material exiting the basket from the second end; the vibrating device connected to the basket for vibrating the basket; the sieve apparatus supported by the basket, with material flowing into the sieve apparatus for treatment; angle adjustment device connected to the basket for adjusting the basket angle by articulating the first end of the basket; sensor device connected to the vibrating separator to detect a parameter indicating the basket angle and to provide a signal corresponding to that basket angle; control apparatus for receiving signals from the sensor apparatus and for basket angle control based on such signals; and angle adjustment apparatus including apparatus for moving the second end up and down for changing the basket angle, the handling apparatus being controlled by the control apparatus.
[0022] [022] The present invention, in certain aspects, discloses a vibrating separator with a base; a basket movably mounted on the base to support the sieve apparatus for treating the material introduced in the vibrating separator, the basket on a base and articulated with respect to this base; vibrating device connected to the basket for basket vibration; sieve apparatus supported by the basket, with material flowing into the sieve apparatus for treatment; angle adjustment device connected to the basket to adjust the angle of the basket; sensor apparatus for detecting a parameter indicating basket angle and for providing a signal corresponding to such basket angle; control apparatus for receiving signals from the sensor apparatus and for basket angle control based on such signals; the angle adjustment apparatus including a rocker assembly with a first end and a second end, the first end pivotally mounted with respect to the adjacent base and under the material inlet area of the vibrating separator and the second adjacent and below the material outlet end of the vibrating separator; and the angle adjustment apparatus including a movement apparatus with a part of it in contact with the second end of the rocker assembly for movement of the second end up and down to change the basket angle, the movement apparatus being controlled by the recording equipment.
[0023] [023] The present invention discloses, in certain configurations, margin adjustment apparatus for adjusting the margin extension in the sieve of a vibrating separator, the sieve mounted on the vibrating separator basket, the margin adjustment apparatus having a support basket with hinged end for basket support, the basket with hinged end being pivoted at the respective hinged end, the basket with hinged end having a second end away from the hinged end, the second positionable close to the outlet end of the vibratory separator, apparatus for articulating the basket support with the articulated end at its respective articulated end, and the apparatus for articulation of the basket support with the articulated end including movement apparatus for handling the second end of the basket support with the articulated end to facilitate the movement hinged basket support with hinged end to raise and lower the second end, to adjust the extent of the margin.
[0024] [024] The present invention, in certain configurations, discloses a vibratory separator (in a particular aspect, a shale shaker) that has a sensor apparatus for detecting parameters indicating the level of fluid or material in a supported sieve or set of sieves by the separator and, thus, to indicate the extension of the margin area of the sieve or set of sieves. In one aspect, the sieve or set of sieves itself (or a sieve in a support structure) is capable of being tilted to a desired angle, to adjust the extent of the margin area adjacent to the outlet end of the sieve. A margin area is an area adjacent to the exit end of a sieve, with two bordering sides - a first side (or rear side) is the side of the puddle for materials in the sieve (analogous to a margin border) and the second side or front side is at, or near the exit end of the sieve. It is important, in some systems, to maintain a margin area to the desired extent, which is sufficiently large, so that the puddle does not extend up to or beyond the exit end of the sieve - which would result in the non-treatment of some material ( filtered, separated) through the sieve, simply overflowing from the end of the sieve. It will also be important, in some systems, to ensure that the margin area is not too large, which could adversely affect the efficiency and effectiveness of the screening.
[0025] [025] In certain aspects, the separator also has an adjustment device (powered electrically, hydraulically or pneumatically) for receiving information from one or more detection devices, related to the distance of the fluid or material, in a specific location of the sieve or set of screens (corresponding to the depth of the pool in place) and then to adjust the angle of inclination of the screen or set of screens, in order to adjust and maintain the extension of a margin area adjacent to the outlet end of the screen.
[0026] [026] In certain respects, any suitable point of articulation of the basket is used from the center of the basket to the end of the basket. In a particular aspect, the basket for supporting the sieve or set of sieves is positioned and configured so as to be articulated at a point of articulation relatively close to one of its ends; and, in a particular aspect, such articulation is below the rear line which is the rear border of the desired margin area ("rear" meaning the margin limit furthest from the exit end of the sieve).
[0027] [027] The present invention, in certain aspects, discloses a shale shaker or vibrating separator with a sieve holder or basket to support the sieve apparatus for treating the material introduced in the vibrating separator, the basket on a base and articulated with respect to this base; vibrating device connected to the basket for basket vibration; sieve apparatus supported by the basket, material flowing into the sieve apparatus and forming a puddle in the sieve apparatus, and a margin in the sieve apparatus adjacent to the puddle; measuring sensor device connected to the vibrating separator and positioned above the sieve device to measure the distance from the measuring sensor device to the upper surface of the puddle, the measuring sensor device including a signal production section for producing indicative signals of such distance and for transmission of these signals; a control system for controlling and communicating with the measuring sensor apparatus for receiving signals from the measuring sensor apparatus indicating such a distance and for processing these signals to calculate the depth of the puddle corresponding to that distance, with such depth of the puddle being related to a location on the edge of this puddle, adjacent to the margin; and angle adjustment device connected to the basket and controlled by the control system for adjusting the angle of the basket, thus adjusting the extension of the margin.
[0028] [028] In a particular aspect, the shale shaker in accordance with the present invention consists of a vibrating basket that supports multiple screens. The drilling fluid is directed so that it flows directly over the sieves, from a spillway tank. As the fluid flows over the sieves, the drilling fluid and smaller particles pass through the sieves and return to the drilling fluid system. Larger particles and parts remain on top of the screens and the vibrating action moves them to one end of the agitator. Inside the agitator, the basket's seating angle can be changed to maintain the desired margin area. One or more ultrasonic transducers measuring devices mounted on a sieve or sieves, (in one respect, above the last sieve) measure the fluid level in the sieve (s) or the last sieve.
[0029] [029] In a particular aspect, a single sensor is used above the puddle that is above the last sieve, which is a less turbulent puddle area than the previous sieve areas and, in one aspect, a basket pivot point it is located below the rear margin line, so that the single sensor provides all the necessary information for adjusting the margin extension, as desired. The fluid level in the sieve (s) is related to the inner or rear limit of the margin. A signal from the sensor (s) indicating the distance between the sensor and the surface of the puddle is sent to a control system, such as a computerized control system, a control system based on a programmable logic controller, a digital signal processor and / or a microprocessor based control system that interprets the signal and sends a control signal to a height adjustment device, such as, without limitation, a system with a directional control valve that controls the flow of pressurized hydraulic fluid to the attached pistons through connections between the base and the agitator basket and / or any basket lifting device (mechanical, pneumatic or hydraulic; such as, without limitation, hydraulically powered piston / cylinder devices) of the technique previous. In certain respects, multiple distance measurements are made and the controller is programmed to average the measurements. As the basket is lifted or lowered, the basket angle changes. When the width of the margin is too long, the height adjustment device decreases the angle of the basket, and when the width of the margin is too short, the angle of the basket is increased. In this way, the desired margin extension is automatically maintained. The distance between the sensor and the desired puddle surface, and thus a desired margin distance, can be programmed in the control system for a specific separator, agitator, sieve or set of sieves.
[0030] [030] In a particular aspect, a force system for supplying hydraulic fluid under pressure to the apparatus for raising and lowering the basket uses hydraulic cylinders with double rods so that double appliances on both sides of a basket can work in harmony. One or more sensors may be connected to or on the basket, to a rear tank, to a platform or base, or to a tube or engine assembly. In one aspect, a fluid reservoir (hydraulic fluid or gas) and / or fluid pumping apparatus is part of a vibrating separator system or part of a shale shaker. In a particular aspect, a platform, base, or support for an agitator or part of an agitator supports a fluid reservoir; and the agitator pumping apparatus supplies fluid to the height adjustment apparatus.
[0031] [031] In certain respects, a fluid flow sensor is employed in a vibrating separator or shale shaker, which indicates when the flow of materials is stopped, so that the end of the basket next to the material inlet point can be lowered, so that at the restart of the material flow the angle of the basket is such that the material does not overflow through the exit of the last sieve, without being treated.
[0032] [032] In certain respects, the present invention provides a vibrating separator (such as, without limitation, a shale shaker) with a basket to support the sieve apparatus for treating the material introduced into the vibrating separator, the basket on a base and articulable with respect to this base; vibrating device connected to the basket for vibrating the basket and the sifting device in the basket; sieve apparatus supported by the basket, material flowing into the sieve apparatus and forming a puddle in the sieve apparatus, and a margin formed in the sieve apparatus adjacent to the puddle; measuring sensor device connected to the vibrating separator and positioned above the sieve device to measure the distance from the measuring sensor device to the upper surface of the puddle, the measuring sensor device including a signal production section for producing indicative signals of such distance and for transmission of these signals; a control system for controlling and communicating with the measuring sensor device for receiving indicative signals from the measuring device of such distance and for processing these signals to calculate the puddle depth corresponding to such distance, with such puddle depth being related to a location on the edge of this puddle, adjacent to the margin; and angle adjustment device connected to the basket and controlled by the control system for adjusting the angle of the basket, thus adjusting the extension of the margin.
[0033] [033] In some configurations the invention provides vibrating separators and mud screens and respective methods of use, having one or more characteristics selected from the following: one or more detection devices for detecting parameters indicating the depth of fluid or material in the sieve (s) or sieve assemblies supported by the separator or agitator, the depth of which is related to the extent of the margin area in the sieve (s) or sieve sets; a screen support articulating at one end or close to one of them, for adjusting the angle of inclination of the screen, thus adjusting the margin area; adjustment device for adjusting the sieve tilt angle based on information received from the device or detection devices; sensor (s) to read the distance between the sensor and the surface of the puddle in the sieve (s) and automatically adjust this distance in order to maintain the desired margin extension for a sieve; and, in one aspect, in a last sieve or material exit sieve; and, in one aspect, a single sensor that, in certain configurations, is located above a basket pivot point; material flow detection device so that the basket angle can be adjusted and readjusted according to the state of the material flow; and margin adjustment device for adjusting the sieve margin extension of a vibrating separator or shale shaker.

DETAILED DESCRIPTION OF THE INVENTION
[0037] [037] Now with reference to Figures 2A and 2B, a drilling system 10 in accordance with the present invention includes a rotary drill 12 attached to the lower end of a hollow drill pipe extension 14 suspended from a drilling tower (not shown).
[0038] [038] The drill pipe 14 and the attached drill bit 12 are rotated to cut subsurface formation 16 to form a well hole 18. The drill pipe 14 passes through a wellhead assembly 20 located on the surface . The wellhead assembly 20 controls the flow of drilling fluid into the well. During drilling of the well, drilling fluid 22 commonly called drilling mud is pumped into the hollow drill pipe 14. The drilling mud comes out of nozzles, just like the nozzle 24 of the drill bit 12 and occupies the bottom. 26 from the well hole 18. The drilling fluid coming out of the nozzles 24 pushes the debris or particles generated from the base 26 of the well hole 18 while the drill bit 12 penetrates the formation of soil 16. A flow of drilling mud 22 it then loads the debris and particles upwards, through the annular body of the well 28 (arrows 29) to the wellhead 20. The drilling mud 22 with the particles and debris being loaded or suspended with it, leaves the wellhead 20 at outlet 31 and passes through a duct 30 to the agitator system in accordance with the present invention, which includes a shale agitator 32.
[0039] [039] In the agitator 32, the drilling mud and particles are deposited on one or more screens, which are vibrated so that the larger particles are sieved out of the drilling mud and taken to the top of the screen (s) ( s).
[0040] [040] A liquid part of the drilling mud together with the very fine suspended particles come out through a first exit from the agitator 34 and are received in the mud pit 36.
[0041] [041] Larger particles 44 which are sieved out of the drilling mud stream exit via a second outlet or chute of the agitator 38 and are transported on a conveyor or separator 40 for deposit in a reserve pit 42 or for storage tanks for transportation to another location. The drilling mud is pumped from the mud pit 36 through a pipe 46 by a mud pump 50. The mud pump 50 then pumps the mud through a discharge pipe 52 which returns it to the inner hole of the pipe for drilling 14.
[0042] [042] As shown in Figures 2A and 2B, the shale shaker 32 has a fluid level detection device 60 that is in communication with the control device 70. The detection device 60 detects the distance to the upper surface of the drilling mud 22 through a sieve 33 of the agitator 32, this being indicative of the depth of the mud. By means of a signal transmission line 62 (or multiple lines, if necessary) the detection device sends a signal indicating this distance to the computer device 70. The device 70 controls the detection device 60 by means of a line 63 (or multiple lines, if necessary).
[0043] [043] The shale shaker 32 (or a respective sieve support basket) is supported by a first support 37 which has an articulating connection 39 and a second support 51 which has an articulating connection 52 and a movable post 53 which is selectively movable up and down, by a moving device 54, in order to articulate the shale shaker 32 (or just its basket) in the articulating connection 39, in order to affect the angle of the shaker or basket 32, the depth of the drilling fluid under the detection apparatus 60, and the extension of the margin area in the sieve 33. By means of a cable 65 the computer apparatus 70 controls a control apparatus 72 which selectively operates the handling apparatus 54 (which may pneumatically, hydraulically or electrically, depending on the height adjustment device or apparatus of any system in accordance with the present invention).
[0044] [044] The detection apparatus 60 may be (and as may be the case for any sensor in any system disclosed herein) any detection apparatus of known and appropriate level and / or distance, including, without limitation, the following types: electrical , optical, electromagnetic, ultrasonic, acoustic and pulse-echo, and may be like the level detection systems disclosed in US Patents 6,691,025 B2; 5,793,705; 5,319,972; 6,484,088 B1; 6,062,070; and 5,131,271 (all said patents fully incorporated herein, for all purposes) and the systems referenced, referred to or mentioned in these patents. Apparatus 70 may be (as may be the case for any system disclosed herein) any computer, computers, computer system, microprocessor based system and / or programmable logic controller.
[0045] [045] Figure 3 shows a shale shaker 100 in accordance with the present invention that has a basket 101 vibrated by an interconnected vibrating apparatus 107. Basket 101 supports three screens 102, 103, 104 for treating material introduced into the screen. 104 from a tank 106. An ultrasonic level sensor 110 is connected to basket 101 and selectively detects the distance to, and thus, the level of material 114 (such as drilling fluid with entrained solids) at a location 116 above sieve 103. A control device 111 controls sensor 110 via a cable 118 and also via cable 118 the sensor 110 sends signals to the control device 111 indicative of the level measurement at location 116. In one aspect , the control device 111 includes suitable devices (such as the device 70 described above) that calculates the depth of site 116 and, based on an appropriate programming in a suitable programming medium on the control device 111, adjusts the inclination of the basket 101 using an adjustment device 112, so that the depth of the location 116 is maintained at the desired level.
[0046] [046] In one aspect the basket 101 is hingedly connected to a support 113 at the pivot point 115. The support 113 is attached to a base 105, as well as the tank 106 and the adjusting device 112. The fluid or solid material that flows through sieves 102 - 104 flows into a receptacle 117. Separate material 108 flows to the outlet end of the last sieve 102.
[0047] [047] Figure 4 shows a shale shaker 120 in accordance with the present invention, similar to shale shaker 100, of Figure 3 (and similar numbers indicate similar parts); but the shale shaker 120 has individual tilt mechanisms 131, 132, 133 (each with its respective pivot point 131a, 132a, 133a) each below the respective sieve 121, 122, 123. The drilling fluid levels 128 in the different locations of screens 121 - 123 they can be adjusted by means of selective alteration of the inclination of screens 121 - 123. Control devices 134-136 correspond, respectively, to mechanisms 131 - 133. A control system 127 with a suitable device The control (such as device 70, Fig. 2B) communicates with control devices 131 - 133 and also with individual level sensors 124, 125 and 126. Each sensor 124-126 detects the drilling fluid level 128 at respective locations 137, 138 and 139. The control device, in one aspect, is pre-programmed to maintain drilling fluid levels at locations 137 - 139 within predetermined levels, monitoring levels with sensors 124 - 126 and adjusting the depths of such locations by articulating sieves 121 - 123, articulating the individual tilt mechanisms 131 - 133. Each or every two of the sensors 124 - 126 can be excluded and the corresponding mechanism (s) slope and associated control (s) can also be excluded.
[0048] [048] Figure 5A shows a prior art shale shaker with a pivot point at or near the mid point of the shaker basket ("fine sieve basket"). Figure 5B shows a shale shaker 150 accordingly with the present invention having a basket pivot point 161 at or near one end of the basket 160. The agitator 150 has a rear tank 151 from which the material to be treated flows into a classification basket 170 that removes parts and solid and / or coarse particles and through which the material then flows to the sieves 153 - 156. A height adjustment device 158 (controlled like any adjustment device disclosed here) selectively articulates basket 160 on point 161. The device of vibration 157 vibrates the basket 160. The material that passes through the sieves flows to a receptacle 159 on a platform 165.
[0049] [049] In one aspect, the present invention provides a separator such as that disclosed in U.S. Patent 4,082,657 (here fully incorporated for all purposes); but with improvements in accordance with the present invention. As shown in Figure 6, a separator device D in accordance with the present invention for separating particulate material from a liquid stream includes a structure 210 which carries an inlet tank 211 for receiving the fluid to be filtered or cleaned. Screen units 214a and 214b are cascaded over the frame 10 by means of a vibrating support generally designated as 215a and 215b, each including a vibrating means 216 mounted on it, for simultaneous vibration of the screen units 214a and 214b.
[0050] [050] Structure 210 includes a first and a second side member 210a (only one is shown) which are connected together by means of a front connecting rod 210b and a rear connecting rod 210c. The front and rear connecting rods 210b and 210c cooperate with the lateral members, such as 210a, in order to provide a generally rectangular shape, presenting an opening along itself, through which the clean fluid stream can pass to a recovery area. positioned below. The side members of the structure, such as 210a, can be I-beams or other members suitable for supporting the structure disclosed herein.
[0051] [051] The inlet tank 211 has a connected inlet line 211b to receive fluids to be cleaned. In one aspect, the sieve unit 214a and 214b includes a metal frame containing sieving material.
[0052] [052] The sieve units are removably mounted on the sieve unit mounting brackets 222 and 222a.
[0053] [053] Each sieve unit is supported by four adjustable posts 235 (two of which are shown on each side of each sieve; as, for example, described in U.S. Patent 4,082,657). Optionally, interposed between the supports of the sieve units 222, 222a are spring mechanisms 233 and 234. Vibratory devices 216 vibrate the sieve units.
[0054] [054] A sensor 240 on a support 240a detects the depth of the fluid in the screen unit 214a and a sensor 242 on a support 242a detects the depth of fluid in the screen unit 214b. A control device 250 (similar to any one disclosed here) maintains signal communication with sensors 240, 242 via cables 243, 244. Control device 250 is also in communication via cables 247, 248 with control devices 245, 246 that control the height-adjustable posts 235. Control devices 250, 245, 246 can be similar to any control device and / or computer device described above.
[0055] [055] Figure 7 shows three sieve assemblies 261, 262, 263 in accordance with the present invention, which can be used in any system in accordance with the present invention, in which the sieve assemblies, sieves, or sieve holders be tilted or moved to adjust the fluid depth at a location on a set of screens or a screen. Each screen set 261 - 263 has an expandable member 264 (such as, without limitation, an extensible bellows or an extensible seal) that ensures that a seal contact is maintained between adjacent screen sets (or between the end of a screen set). sieves and a limb in a basket, against which the end of the set of sieves rests). In one aspect, as shown, the extensible members 264 are bellows seals; but it is within the scope of the present invention to use any seal or sealing material that can expand and contract sufficiently to maintain an adequate seal between adjacent sieves.
[0056] [056] Figures 8A-8C illustrate a set of screens 265 in accordance with the present invention that has a flexible front seal 266 that is applied against the end of an adjacent screen 267. Seal 266 is wide enough to seal the end of the screen. screen set 267 when the inclination of the screen set 267 is changed (and / or when the inclination of the screen set 265 is changed (as, for example, in response to a signal from a fluid level sensor over each or both sieve assemblies 265, 267)). Optionally, the screen set 267 may also have a front seal 264.
[0057] [057] Figure 9 shows a vibrating separator 270 in accordance with the present invention with walls 274 and a set of screens 271 in a configuration adorned with the fluid 272 to be treated. A fluid level sensor 273 connected to a wall 274 of the separator 270 with a connector 275 detects the fluid level near the center point of the screen set 271 (as seen in Fig. 9). A fluid level sensor 276 detects the fluid level near the wall 274. It is within the scope of the present invention to place one or more fluid sensors at any point on a set of screens on a vibrating separator or agitator. Optionally, any of the 273 or 276 sensors can be excluded.
[0058] [058] Figures 10A-10D shows a shale shaker 300 in accordance with the present invention that is similar to a "King Cobra shale shaker" commercially available from Varco International, Inc., but having improvements in accordance with the present invention. . The shale shaker 300 has a platform or base 302 on which a basket 306 is vibrated by means of a vibrating device 304. From a spillway tank 308, the fluid, such as the drilling fluid containing debris and waste, flows to a first sieve 310 which is supported by a sieve holder 310a connected to basket 306. Part of the fluid then flows into a second sieve 311 supported by a sieve holder 311a connected to basket 306, and then part of the fluid flows into a last sieve 312 supported by a sieve holder 312a connected to the basket 306. Part of the fluid flows through an outlet end 312b of the sieve 312 to a lower optional sieve 313 which is supported by a sieve holder 313a connected to the basket 306. The sieve holders 310a, 311b and 311c can be attached to their respective sieves 310, 311, 312 by means of suitable clamping devices, such as one or more electromagnetic clamping devices 314, or others suitable fixing devices. The electromagnetic clamping device 314 can be of the type that is energized and / or de-energized by means of a simple transient electrical pulse. That is, a demagnetized fixation device can be placed in a magnetized state and remain in a magnetized state by means of a transient electrical pulse signal from some type of control device or other suitable source. Another pulse from the same source or from a source can then return it to the demagnetized state and the fixer will remain in that state, indefinitely, until it is energized again. To help compensate for the additional mass of these magnetic fasteners, a constant 'G' force controller (not shown) may be included in the controller control system to ensure that vibration accelerations are kept within acceptable limits. The transient pulse signal can come from any suitable control device or any other suitable input medium.
[0059] [059] The fluid forms a puddle 315 above the 310-312 sieves. Depending on the fluid, viscosity or solid content, flow rate of the aforementioned, and the exit time of the sieves, a margin 316 is created at the outlet end 312b of the sieve 312. It will be desirable to optimize the extension of this margin 316 and, in certain aspects , it is preferred that this margin, as seen in Fig. 10B, is large enough that no untreated fluid can escape the last sieve 312.
[0060] [060] An ultrasonic transducer sensor measuring device 320 is connected to the basket 306 (such as, for example, to a motor tube 309 and / or connecting the sensor device 320b to a spillway tank 308) and is optionally positioned above the puddle 315, such as on the inlet end 310b of the sieve 310 or on the inlet end 312c of the sieve 312. Such locations for apparatus 320 will provide measurements of locations that offer the greatest depth range of the puddle, and thus, the greatest range for adjusting the margin extension; that is, these locations guarantee that the devices 320a and / or 320b will have a distance between the sensor and the surface of the puddle suitable for measuring, since in most cases there will be fluid at some depth, at this point, below the device or devices 320. The devices 320a and / or 320b are in communication with the control device 330. The sensor devices generate a signal indicating the distance from the sensor to the puddle that indicates the depth of the puddle 315 under the sensor device (s) ( es). Optionally, both sensor 320a and sensor 320b can be excluded.
[0061] [061] Control device 330 (such as, for example, a computer, PLC, PID controller, or other device with programmable means) selectively controls a control valve 336 that allows hydraulic fluid under pressure from a reservoir 338, pumped by a 337 hydraulic pump can move towards and away from two hydraulic cylinder devices (one shown in Fig. 10A) positioned on opposite sides of the agitator 300. A flow control valve 332 controls the flow of fluid to in and out of the pistons and adjust the stroke rate of cylinder devices 333, 334 and a flow control valve 335 limits the flow of fluid in and out of the pistons, and adjust the stroke rate of cylinder devices 333, 334. A hydraulic cylinder apparatus 350 has an extendable piston 351 hingedly connected to a hinge plate 353 at a hinge point 365. Plate 353 is hingedly connected to a hinge point. joint 357 of basket 306. A housing 350 of apparatus 334 is attached to a bracket 359 which is pivotally connected to basket 306. A connection 355 is pivotally connected to plate 353 at a pivot point 366 and connection 355 is connected to a connection 356 which is pivotally connected to a pivot point 354 of the basket holder 340. The basket holder 340 is supported by the hydraulic cylinder apparatus and the bases 341. The axles 367 of the basket supports 340 are pivotally mounted on the bases 341 A graduated ruler 339 indicates the horizontal angle of the support 340 (that is, assuming the platform or base 302 is level). The support 340 is connected to springs 346, 343 that support the basket supports 345 and 342, respectively; and similar springs and supports are found on the other side of the basket.
[0062] [062] In another aspect, the plate 365 is excluded and the hydraulic cylinder apparatus is oriented almost vertically, and the pistons of the hydraulic cylinder apparatus 351 are articulated to the basket support 340 to be selectively raised and lowered in a way adjusting the extent of the margin.
[0063] [063] Figure 10C shows basket 306 tilted, compared to basket 306, as shown in Figure 10A.
[0064] [064] In one aspect, a vibrating separator or shale shaker in accordance with the present invention can employ a material flow sensor that produces a signal indicative of the presence or absence of material flowing into the sieve apparatus; such as, without limitation, drilling fluid with excavated solids flowing into the sieve apparatus of a shale shaker. Such indication is valuable to ensure that, during the restart of the flow after the cessation of a flow of material, which is common when the drilling is interrupted, no sieve or basket is tilted at an angle that allows the formation of a deep puddle relatively low, as a result of the loss of untreated drilling fluid flowing through the sieve outlet end. By adjusting the angle of the sieve or basket so that the restart of the flow is accommodated, a puddle of sufficient depth and length will be formed, so that the vast majority of the material is treated and an optional amount of drilling fluid flows through the sieve and be recovered.
[0065] [065] Optionally, an agitator 300, as shown in Figures 10A and 10B (with or without a sensor or sensors such as sensor 320a and / or 320b) has a material flow switching device 307 connected to the vibrating separator adjacent to a material inlet tank, such as tank 308, for detection while material is flowing. The 307 device may be any suitable known flow sensor device, including, without limitation, controller switch systems, including, without limitation, the FS-550 Series limit switches from Gems Sensors Co.
[0066] [066] Device 307 is in communication and is controlled by controller 330 and, in one aspect, signals from device 307 overlap with sensor signals, such as sensors 320a and 320b, so that controller 330 knows that the flow of material was interrupted (instead of the indication of sensors 320a, 320b that the puddle is very shallow). In response to signals from device 307, controller 330 can activate the apparatus for adjusting the basket angle.
[0067] [067] Once the material flow in the basket is resumed again, controller 330 (acting on signals from sensor 320a and / or sensor 320b) adjusts the angle of the basket to maintain the desired margin extension. Although a specific flow sensor has been mentioned, it should be understood that any flow sensor device or system can be used, including, without limitation, ultrasonic transducer systems.
[0068] [068] Controller 330 may be any known suitable commercially available controller device, including, without limitation, computer systems, digital signal processing systems, programmable logic controller systems and / or microprocessor systems. A suitable sensor device and associated control system are Siemens' XPS-10 and Hydro Ranger 200 models.
[0069] [069] Figure 10F schematically shows a vibrating separator or shale shaker 400 in accordance with the present invention that has a sieve support basket 402 with articulated members 414 hingedly mounted on supports 404 on a platform or base 406. Apparatus adjustment brackets 408, 410 on each side of the basket 402 (like any adjustment apparatus described here) raise and lower one end 412 of the basket 402, pivoting it around the hinge members 414. In one aspect, the rear line 416 of the area margin 420 of a sieve 430 supported in a basket 402 coincides with the line between the hinged members 414.
[0070] [070] A sensor 418 (like any sensor disclosed herein, including, without limitation, those in Figures 1-10A) is positioned above the fluid inlet end of the sieve 430, on a connection member 422 connected to basket 402. One sensor 451 (like any sensor described here) is positioned above the fluid inlet end of sieve 434 and can be conveniently connected to a bar or beam connected to tank 450 and / or basket 402. Material flows from sieve 432 to the sieve 430 and sieve 434 to sieve 432. Any suitable tank 452 and / or fluid introduction apparatus may be used. The vibrating apparatus 440 vibrates the basket 402.
[0071] [071] A power device 441 connected to the agitator 400 energizes the adjustment devices 408, 410 and can be positioned in any suitable location on the agitator 400, including, without limitation, in basket 402 or on platform 406. Optionally, the force 441 may be any device or system disclosed herein. In one aspect, the power device 441 includes a hydraulic pump in communication with a hydraulic fluid reservoir, 440 through a pipe 444 and the devices 408, 410 are hydraulically powered devices in fluid communication with the pump through pipes 442, 443 The control device 450 (like any of the ones disclosed here) controls the device 441, the sensor 418, a sensor 460, a controller 456, and / or the sensor 451. Optionally, a material flow sensor 460 connected to the tank 452 (or any other suitable location on separator 400), which is similar to sensor 307, in Figure 10A, detects the presence or absence of material flowing from tank 452 to sieve 434. Sensor 460 is in communication with the control device 450 and, in response to signals from sensor 460, control device 450 adjusts the angle of the basket to accommodate the flow of material and adjusts for the flow to resume after a flow interruption. Optionally, a flow rate controller 456 controls the amount of fluid introduced into the sieve 434 from the spill tank 452 and a control key 455 from the controller 456 is in communication with the control device 450.
[0072] [072] It is within the scope of the present invention to locate devices 408, 410 in any effective desirable location, with respect to the basket, as may be the case with any adjustment apparatus disclosed herein.
[0073] [073] The present invention, therefore, in some and not necessarily in all configurations, provides a vibrating separator having a sieve holder or basket to support the sieve apparatus for treating the material introduced in the vibrating separator, the basket in a base and articulated with respect to this base, vibrating apparatus connected to the basket for basket vibration, sieve apparatus supported by the basket, the material forming a puddle in the sieve apparatus, and a margin in the sieve apparatus adjacent to the puddle; measuring sensor device connected to the vibrating separator and positioned above the sieve device to measure the distance from the measuring sensor device to the upper surface of the puddle, the measuring sensor device including a signal production section for producing indicative signals of such distance and for transmission of these signals, a control system to control and communicate with the measuring sensor apparatus for receiving signals from the measuring sensor apparatus indicative of such distance and for processing these signals to calculate the puddle depth corresponding to such distance, and angle adjustment device connected to the basket and controlled by the control system to adjust the angle of the basket, thus adjusting the extent of the margin. Such a vibratory separator may be characterized by one or some, in any possible combination, of the following facts in which: the vibratory separator is a shale shaker and the material is a drilling fluid containing excavated debris; the sieve equipment includes at least one outlet sieve with an outlet end, through which the material separated by the sieve equipment flows from the sieve equipment to discharge the vibrating separator, the basket remains at an angle such that the margin is formed adjacent to an edge of the puddle adjacent to such an outlet end, and the control system controls the extent of the margin; the control system controls the extension of the margin in order to maintain the margin on the exit screen; the sieve equipment is a plurality of sieves positioned adjacent to each other in the basket, each sieve with an associated sieve holder connected to the basket; the angle adjustment equipment includes a basket support articulated to the base and the handling equipment for selective movement of the basket, up and down; the basket has an end for fluid inlet and an end for fluid outlet and the basket is pivotally mounted adjacent to the end for fluid outlet, and the angle adjustment equipment moves the end of the basket to the fluid inlet; the handling equipment includes a hydraulic cylinder device for moving the basket; the hydraulic cylinder device includes two hydraulically powered piston devices, each on one side of the basket for moving the basket; each hydraulically powered piston device is interconnected articulatively with the corresponding connection equipment, the connection equipment being articulated to the basket support adjacent to the end of the basket's fluid inlet; the measuring sensor equipment is an ultrasonic equipment; ultrasonic equipment is at least ultrasonic equipment; the measurement sensor equipment is a plurality of distance sensor equipment; the plurality of sensor equipment includes a first ultrasonic sensor equipment spaced from a second ultrasonic sensor equipment, the first ultrasonic sensor equipment above one side of the sieve equipment and the second ultrasonic sensor equipment above the opposite side of the sieve equipment; the measuring sensor equipment belongs to the group consisting of electrical, optical, electromagnetic, ultrasonic, acoustic and pulse-echo equipment; the rear margin of the margin follows the rear margin line and the basket is articulably connected to the base below the rear margin line; and / or the angle adjustment equipment is powered by the power equipment.
[0074] [074] Figures 11A-11D show the shale shaker 500 in accordance with the present invention, which is similar to the King Cobra Shale Shaker commercially available from Varco International, Inc., but containing enhancements in accordance with the present invention. . The shale shaker 500 has a platform or base 502 on which the basket 506 is vibrated by the vibrating equipment 504. From a tank 508 the fluid, such as, for example, drilling fluid containing excavated debris and waste , flows to a first sieve 510 which is supported by a sieve holder 510a connected to the basket 506. Part of the fluid then flows to a second sieve 511 supported by the sieve holder 511a connected to the basket 506 and then part of the fluid flows to a last sieve 512 supported by a sieve holder 512a connected to the basket 506. Part of the fluid flows through the outlet end 512b of the sieve 512 to a lower sieve, optional 513 which is supported by a sieve holder 513a connected to the basket 506. O fluid flows into a tank or receptacle 503 positioned lower.
[0075] [075] The fluid forms a 515 puddle on the 510-512 sieves. A margin 516 is formed at the outlet end 512b of the sieve 512. It will be desirable to control and / or optimize the extent of this margin 516 and, in certain aspects, it is preferable that the margin, as seen in Fig. 11B, is large enough for no untreated fluid flows out of the last 512 sieve.
[0076] [076] An ultrasonic transducer sensor measuring device 520 is connected to the shale shaker, such as, for example, to a platform, base, tank or, as shown, to basket 506 and is optionally positioned above puddle 515, such as, for example, on an input end 510b of sieve 510. Equipment 520 is in communication with control equipment 530 (such as, without limitation, a computer). The sensor equipment generates a signal indicating the distance from the sensor to the puddle, which indicates the depth of the puddle 515 under the sensor equipment (s).
[0077] [077] The control equipment 530 selectively controls a bladder-type device 536 that selectively raises and lowers the rocker assembly 540 which, in turn, raises and lowers the basket 506 to which the rocker assembly 540 is connected. Optionally the angle of the rocker assembly is selectively adjusted horizontally by a mechanical mechanism, such as, for example, any suitable mechanical mechanism known for moving the rocker assembly up and down, such as, without limitation, a screw mechanism or a hydraulic or pneumatic piston device.
[0078] [078] An upper part 536a of the bladder-type device 536 contacts the lower surface 541a of a plate 541 of the rocker assembly 540. The bladder-type device 536 inflates to raise the rocker assembly 540 and deflate to lower it. A gas, such as air, for example, a liquid, such as a mixture of water and glycol, for example, can be used to inflate the bladder-type device 536. The control equipment 530 controls the bladder-type device 536. Instead of using the air bladder-type device 536 to move the rocker assembly up and down, it is within the scope of the present invention to use: a linear actuator device or other electronically operated device; a hydraulically operated device, such as, for example, a hydraulic cylinder system; or air-powered hydraulic equipment, such as, for example, a liquid-filled tank system with air pressure. In a specific configuration, the 536 air bladder device is a Model 20-2 commercially available from the Firestone Company. Although only one air bladder type device 536 is shown, it is within the scope of the present invention to use two such devices, one on each side of the 506 basket.
[0079] [079] The rocker assembly 540 has articulation shafts 542 that rotate in the corresponding recesses 543 of the supports 544 on the platform 502. The rocker assembly 540 has two side members 545 interconnected with a front member 546. Spring supports 54, welded to the basket 506, support the springs 548 connected to the brackets 549.
[0080] [080] An optional ultrasonic sensor equipment 522, in communication with control equipment 530, checks whether or not there is a flow of fluid from tank 508 to puddle 515. If a “no flow” signal is generated by equipment 522 and sent to control equipment 530, then the basket will be tilted to its maximum upward angle in anticipation of the next load of mud. An optional ultrasonic sensor equipment 524 detects the location (height) of the plate 541 and produces a signal indicating that location, a signal whose value will correspond to the angle of the rocker assembly 540 and, thus, the angle of the basket 506 (and which will be correlated to the signal values of equipment 522). In one aspect, the control equipment 530 computes the basket angle based on the signal from the ultrasonic sensor equipment 524 and correlates this computed angle with the puddle depth value, based on the signal from the ultrasonic sensor equipment 520. If these two values match, this will indicate that the system is operating correctly. If there is a discrepancy between the values (of the ultrasonic sensors) (such as, for example, discrepancy caused by high flow, basket orientation down or low fluid level) this will indicate a measurement problem and the 530 control equipment will then adjust the basket at a maximum upward angle until there is no such discrepancy.
[0081] [081] Optionally, the shale shaker 500 includes a frequency converter 550 (optionally in an enclosure rated for Class 1, Division 1, or Zone 1 hazardous area) whose functions include the RPM range of the 504 vibrating equipment and, thus, the variation of the G forces (acceleration) transmitted to the basket 506 by the vibration equipment 504; and changing the direction of rotation of the vibrating equipment 504, thereby changing the movement of the basket 506, such as, for example, from linear movement to elliptical movement. In a particular aspect, the 504 vibration equipment includes a Model VMX 18-8300-80 or Model VMX 18-8300-110 vibrator from Martin Engineering, equipped with dual motion motors capable of changing a weight imbalance based on the direction of the movement. rotation, to change the movement, such as, for example, from linear to elliptical (or vice versa). The control equipment 530, and / or the ultrasonic sensor equipment 524 and / or the device 550 can be located in any convenient location of the shale shaker 500. As shown in Figure 11A, these are protected by an enclosure 554 formed by parts of the shale. tank, made of resilient material, such as, for example, metal or compound. Alternatively, driver 550 is located in a separate compartment 554a (shown by the dotted lines). Equipment 552 provides a channel 553 for fluid in tank 508 to bypass sieves 510-512 and flow directly into receptacle 503.
[0082] [082] Figure 13 shows a computer 560 that can be used, in one aspect, for control equipment 530. Optionally, the computer 560 is positioned inside a compartment 561 suitable for installation in a Class 1, Division hazard zone. 1 or Zone 1. AC power is applied to an AC to DC 562 transformer that supplies power to a 579 power supply and to a 563 power supply (which in turn supplies power to barrier devices 564, 565, and 566). The power supply 563 supplies power, such as, for example, 24 VDC, to the power supply 567 of an Input / Output device 568. The power supply 579 supplies power (such as, for example, 5 VDC) to a 569 single-board computer that runs a control program and reads the Input / Output Device, and sends control signals to electrically actuated valves (such as, for example, 670, 671, in Fig. 14) to control the angle from the agitator basket. Force barrier devices 564 - 566 supply power, such as, for example, 24 VDC, to various intrinsically safe ("IS") devices, such as, for example, ultrasonic sensor equipment. The 569 computer can be programmed to provide a basket angle “reset” to reconfigure a measurement value of the ultrasonic sensor equipment in a “home” position of the basket (such as, for example, the maximum angle ascending).
[0083] [083] Analog barrier devices 571 and 572 limit the energy of signals in analog devices, that is, ultrasonic sensors. The 567 power supplies power to the 573 - 576 devices. A 573 digital input card receives digital input signals from other devices, such as, for example, the frequency converter and user push buttons. A digital output card 574 sends digital signals to other devices, such as, for example, the frequency converter. A 575 relay board provides switch openings and closures for sending control signals to other devices, such as, for example, control valves. An analog output card 576 receives analog signals from other devices, such as, for example, ultrasonic sensor equipment.
[0084] [084] Optionally, the Input / Output device 568 may have a 578 key or connection for communicating with a system (such as, for example, a computer or computer system) separate and / or remotely positioned with respect to the shale shaker or vibrating separator, such as, for example, without limitation, to an Ethernet Input / Output Controller which, in turn, will provide the connection to other systems, such as, for example, the Internet.
[0085] [085] Figure 14 schematically illustrates a system 600 in accordance with the present invention that is similar to the systems shown in Figures 11A-13. An agitator 601 (such as, for example, agitator 500 or any agitator disclosed or referred to herein) has a rocker assembly 640 (such as, for example, assembly 540) that can be raised and lowered by a bladder-type device 636 (such as, for example, equipment 536) that is mounted on platform 602. Vibrating motors 604 (such as, for example, motors 504) vibrate a basket 606 (such as, for example, basket 506).
[0086] [086] Ultrasonic sensor equipment 620, 622, 624 (such as, for example, equipment 520, 522, 524) provides signals to a 630 control system (such as, for example, control equipment 530) for detecting system parameters, to control the rocker assembly to adjust the basket angle and to control the 604 motors. The control equipment 630 is housed within a 654 compartment (such as, for example, the 554 compartment).
[0087] [087] An optional frequency converter system ("VFD") 650 (such as, for example, system 550) in a compartment 654a (such as, for example, compartment 554a) remains in communication with the system 630 and provides the control of the 604 motors (that is, the control of the G forces on the sieves and / or control of the type of movement) and control the angle of the basket. In a particular aspect, the 630 system has manually operated pressure buttons 631 - 634. The buttons 631 - 633 are used to calibrate the ultrasonic sensor equipment 620, 622, 624, respectively. The 634 button is a system reset button. In one aspect, the buttons are connected to a digital input card in the compartment.
[0088] [088] The frequency converter 650 has manually operated push buttons 651 - 656 and 658 - 659 that work as follows: 651 - League 652 - Turn off 653 - Changes the motor movement between linear / elliptical 654 - System power 630 655 - Changes the modes between manual and automatic 656 - System reconfiguration 650 658 - Moves the basket up (increases the angle of the basket) 659 - Moves the basket down (decreases the basket angle)
[0089] [089] Valves 670 and 671 are electronically operated valves. Power is supplied to valve 670 via a power line 681 of the 630 system and to valve 671 via a power line 684. The basket is lifted or lowered selectively by opening or closing valve 670 which allows fluid 692 (such as, for example, a mixture of water and glycol) to flow to or from a bladder-type device 636 from a controlled pressure reservoir 691 in pipeline 675 and to or from valve 670 in tubing 677.
[0090] [090] Valve 671 controls the flow of air between an air inlet 672 and reservoir 691. Air under pressure from a source 692 flows from line 693 to air inlet 672 and then through lines 678 and 674 to and from reservoir 691 to move fluid 692 to raise and lower the basket, to adjust the angle of the basket.
[0091] [091] A 673 cooler, such as, for example, a vortex cooler in fluid communication with the air inlet 672 through pipes 678 and 685, cools the interior of compartment 654a.
[0092] [092] Figures 15-17 show a shale shaker 70 in accordance with the present invention that has a basket for mounting on a sieve 72 and a bridge 74 on which two vibrating equipment 75 are mounted. The basket 72 has supports 76 to the helical springs 77 are attached. Each spring 77 is attached to a base element 77a. As shown in Fig. 17, an optional housing 79 can be used on the sides and under the shale shaker 70. Optionally (and, as the case may be, with any shale shaker disclosed herein in accordance with the present invention or with any shaker or vibrating separator of known prior art) an electronic tracking equipment 71 is located in housing 79, but may, in accordance with the present invention, be contained within any appropriate element or part of the shale shaker; and, optionally, such tracking equipment will have a container or housing made of composite material and / or will be encapsulated in or lined with composite material.

[0095] [095] The present invention thus provides, at least in certain configurations, a vibrating separator with a base; a basket movably mounted on the base to support the sieve equipment for treating the material introduced in a first end of the basket of the vibrating separator, the basket in the base and the first articulable end in relation to said, the basket having a second end spaced from the first end, the material exiting the basket from the second end; vibrating equipment connected to the basket for basket vibration; sieve equipment supported by the basket, the material flowing to the sieve equipment for treatment; angle adjustment equipment connected to the basket to adjust the angle of the basket by articulating the first end of the basket; sensor equipment for reading the basket angle indicative parameter and for providing a signal corresponding to that basket angle; control equipment for receiving signals from the sensor equipment and for basket angle control based on such signals; and angle adjustment equipment including equipment for moving the second end up and down to change the basket angle, the handling equipment being controlled by the control equipment.

[0098] [098] The present invention, therefore, provides, in at least certain configurations, margin adjustment equipment for adjusting the margin extension in the sieve of a vibrating separator, the sieve mounted on the vibrating basket of the vibrating separator, the margin adjustment including a hinged end basket support for the basket support, the hinged end basket support at the respective hinged end, the hinged end basket support having a second end away from the hinge end, the second positionable end close to the outlet end of the vibrating separator; equipment for articulating the basket support with an articulated end in its respective articulated end; and the equipment for articulating the basket support with an articulated end including a handling equipment, with a part for contacting the second end of the basket support with an articulated end, to facilitate the articulated movement of the basket support with an articulated end used to lift and lower the second end, in order to adjust the extent of the margin.
[0099] [099] In certain respects, an automatic intensifier minimizes fluid loss through the end of the agitator during a flood situation. Several standard agitators in the prior art operate with fixed vibrating force and frequency, and a manually adjustable basket angle and vibrates at a nominal acceleration rate (g-force) that is measured without drilling fluid. The addition of drilling fluid adds mass to the system, which reduces system acceleration. In addition, the basket angle is usually adjusted manually, depending on the fluid level. Adjusting the basket angle keeps the fluid extent (margin) at a desired point, such as, for example, on triple sieve shakers, near the end of the third sieve. However, when the fluid flow rate changes frequently in the field, it is often the case that the basket angle is no longer adjusted to its ideal position. If the basket angle is left in its fully upward position, several screens can run dry, which can shorten the screen's life. If the basket angle is left in a downward position for the correct extension of the margin, all the mud may be lost at the end of the agitator when the flow rates increase.
[0100] [0100] In certain configurations, the agitator, in accordance with the present invention, automatically adjusts the basket angle according to the fluid level. Thus, the basket is tilted downwards when there is little flow entering the agitator. When the flow increases, the basket is automatically tilted upwards, in order to keep the margin in approximately the same position. If the basket has been tilted fully down and the fluid level is measuring high for a certain period of time (programmable on the computer and / or agitator controller), then the computer will automatically signal the frequency converter (or inverter) so that it starts the engines more quickly, this being referred to as an "automatic intensification" feature. Increasing the engine speed will increase the force applied to the basket and the fluid system. This, in turn, will increase the acceleration of the basket, which in turn will increase the flow capacity of the agitator. Thus, this automatic intensification feature helps to prevent flooding and loss of all the agitator mud.
[0101] [0101] Many traditional agitators of the prior art operate with a fixed movement profile. These movement profiles can be linear, elliptical or circular. Each movement tends to be the most suitable for a specific mud condition. For example, circular motion may perform well with sticky clays, linear motion will perform well under high flow conditions, and elliptical motion may offer a compromise between linear and circular. Some current prior art stirrers can manually switch profiles between linear and elliptical. Such agitators include the Brandt King Cobra +, Brandt King Cobra II and Swaco Mongoose. Certain agitators in accordance with the present invention may have a custom agitator movement profile, elliptical type with varying aspect ratio. A movement profile is the form of movement at different points on the agitator, a movement transmitted to the material that moves on the agitator. For example, the overall performance of the agitator may, in certain respects, be further improved by receiving a different form of movement at the discharge end of the agitator than at the feed end or in the middle of the agitator. In one aspect, the movement tuned at the end of the stirrer is a thin ellipse (approximately 5% aspect ratio), which can appear to be linear; the movement tuned near the center of the basket is a medium ellipse (aspect ratio of approximately 15%); and the movement tuned near the discharge end of the agitator is a larger ellipse (aspect ratio of approximately 30%). The level of acceleration and angle of attack remain fairly consistent and uniform, from front to back. In one aspect, this movement profile improves performance in drilling mud with sticky clays. With this configuration, the conductivity is increased (faster removal of liquid from the sludge) with the thin ellipse at the feed end of the agitator. Conduction is enhanced at the discharge end of the agitator by the more articulated elliptical movement. The more linear movement at the feed end of the agitator processes a higher maximum flow rate of fluid, while the more elliptical movement at the discharge end of the agitator better conveys the sticky clays. Elliptical movement is achieved using different weights on the vibrating motors, creating a differential force that results in a perpendicular movement to the basket's line of force, and a torque imbalance that makes the basket rotate around the center of mass, producing a elliptical movement; and / or such movement is produced by varying the position of the motor, in relation to the center of mass. In an agitator in accordance with the present invention, an operator can manually switch the agitator's motion profile between linear, elliptical and circular motion (with adequate motor location and / or spacing and / or with the motor in the center of mass of the basket ). In another aspect, a stirrer in accordance with the present invention has the ability to produce all three standard movements (linear, elliptical and circular), and a custom movement (changing the shape from front to back in the basket), and thus the best Motion profile can be selected based on the state of the mud and the state of the agitator. For example, if the mud flow rate is too high, the linear motion profile may be the best. If very sticky clays are found, then circular motion may be preferred. If the mud does not contain a lot of sticky clays, and the flow rate is not extremely high, then the elliptical movement may be the best. Other conditions may point to a particular movement, as being the best for the occasion. For example, an intelligent stirrer in accordance with the present invention may select the appropriate movement and turn the motors on and off, or drive the motors forward or reverse to obtain the best movement. The motors may have brakes applied to stop the rotation of the motor weights, in order to obtain the desired movement.
[0102] [0102] Currently, many agitators of the prior art operate in a fixed state or at least with infrequent changes. The state of the agitator can be described by parameters such as screen sieve, acceleration amplitude, movement profile, basket angle, angle of attack and vibration frequency. In addition, many normal stirrers operate without knowledge of the status of the drilling mud. Some of the parameters that contribute to the state of the sludge include viscosity, temperature, flow rate, fluid level in the agitator, specific gravity, solids content and viscosity of the solids. Typically, many prior art agitators are designed to operate under a nominal agitator state that works reasonably well for a variety of mud states. Experienced operators periodically change the state of the agitator to increase the performance of the current mud state. Mud sensors from the prior art can read these parameters. Inexperienced operators will be able to operate the agitator in a sub-ideal state for the mud conditions. Even experienced operators may not have time to change the state of the agitator to match changing mud conditions. A stirrer provided with information about its own state and the state of the drilling mud can operate closer to the ideal under such conditions. Certain agitators in accordance with the present invention evaluate their own performance, to help optimize the operation.
[0103] [0103] In order to operate intelligently, an agitator in accordance with the present invention will have a computer or other equipment that is in some way programmable to read status information, make decisions to optimize performance and implement decisions (such as such as, without limitation, controller 330 of Fig. 10E; control equipment 550 of Fig. 11A, computer 560 of Fig. 13; or control equipment 630 of Fig. 14). The computer, in one aspect, is connected to an I / O (input / output) device or devices that reads values from various sensors and sends an output command to actuators, motor drivers, and / or other equipment. Sensors (such as, for example, sensors inside an agitator, container, tank and / or in a flow or conduit pipe; such as, for example, MS sensors, Figs. 2A and 9) indicate and measure some or all of the mud status parameters.
[0104] [0104] With information on the state of the mud, the present state of the agitator, and / or other performance measures, an intelligent agitator in accordance with the present invention controls its own state to improve and / or optimize performance. Shaker states capable of being controlled (with controls selectable by the user and / or automatically based on sensor readings) include basket angle, acceleration magnitude, movement profile (linear, elliptical, or circular; such as, for example, detect non-sticky, free flowing material and then use floating linear motion; such as, for example, detecting sticky clays and switching to elliptical motion, or detecting low flow for a long time and then switching to elliptical motion), vibrating frequency, angle of attack (angle of movement of the basket relative to its horizontal position; such as, for example, changing the center of mass of the basket and / or the location of the engine).
[0105] [0105] In certain respects, the automatic intensifier feature is a specific instance of controlled acceleration. In this case, the acceleration of the agitator is temporarily increased to a predetermined value, such as, for example, in order to accommodate an unusually high mud flow. More generally, when the agitator's acceleration is controlled, it can then be varied over a continuous range (such as, for example, for such control, a monitoring device monitors an accelerometer installed or connected to the agitator basket and the device monitoring system (such as, for example, a computer, or PLC or PID controller) sends a signal to a frequency converter). For example, acceleration can be controlled to be constant under varying mud flow / load. This is achieved by measuring the acceleration of the basket with an accelerometer located in the basket, in an aspect close to the center of mass, such as, for example, the AC accelerometer in Fig. 11C; feeding the signal from the accelerometer to an agitator computer (or PID Controller, or to a remote computer); comparing the actual acceleration with the desired value; and changing the motor frequency or other driving force until the actual acceleration corresponds to the desired acceleration.
[0106] [0106] If a desired acceleration value is changed according to the states of the agitator and the mud, then the performance will be improved and / or optimized. For example, the level of acceleration can be adjusted to minimize energy consumption or to use the minimum required acceleration based on the fluid level of the agitator. This is useful, as high acceleration can lead to reduced sieve life and solids degradation. If the fluid level in the basket increases above the desired level then the angle of the basket will be reduced in order to tilt the basket upwards. This can only be done to a certain extent. Once the basket is fully tilted downwards, the acceleration will be increased, which will process more fluid and lower the fluid level in the agitator basket.
[0107] [0107] For condition-based maintenance, the agitator machine status and / or agitator history will be used to estimate when the machine should be serviced. The maintenance schedule for a standard agitator usually requires adding grease to the vibrator motor bearings after a specified period of time. Depending on how much the agitator has actually been operated over time, this will cause the actual maintenance schedule to differ from the static, documented schedule. Proper greasing will be especially important for the motor bearings (such as, for example, the BA bearing equipment shown on the dotted lines in Fig. 11C). Too little grease can cause increased friction, increased temperature and premature bearing failure. Too much grease can cause an increase in bearing pressure, an increase in temperature and premature bearing failure. In addition, the ambient temperature under which the engine operates will affect the maintenance schedule. Other factors include the strength of the engine.
[0108] [0108] One factor that can be used to predict when grease will need to be added to the bearing is the bearing's operating temperature. In accordance with the present invention, the operating temperature of the bearing is measured with a sensor (such as, for example, sensors on the motor adjacent to the bearings, such as, for example, the SR sensor in Fig. 11C) and is then sent to a computer that will compare the level of the ambient temperature and the desired temperature for greasing and then the operator can be notified (such as, for example, by means of any controller described here) when it is time to grease the motor bearings. Also, a computer (on the agitator, locally, or remote) or another device is used to track the engine's running time. When the operating time reaches the desired maintenance time, the operator is notified of the need for maintenance. This operating time can be adjusted according to the ambient temperature and the current temperature of the bearing.
[0109] [0109] Certain agitators in accordance with the present invention have interfaces and communications with local and remote controllers, computers, systems, networks, and / or the Internet. An automatic stirrer in accordance with the present invention has a web interface (such as, for example, the Internet) between local personnel present at the stirrers' location and remote computerized personnel and / or information for maintenance and / or reprogramming operations. This allows technicians, during setup, maintenance or troubleshooting to troubleshoot the agitator status, including all program parameters, and adjust program parameters without interruption, with the agitator operating and the software running. Additionally, technicians will be able to upload software updates to the agitator. Software updates can be made through the web interface or by physically changing a programmable medium, such as, for example, a removable Compact Flash card. Such an agitator should have a local Ethernet network, in the agitator's computer compartment. With a wireless radio connected to the agitator's computer network, the agitator's computer will be able to communicate wirelessly through the closed explosion-proof compartment with the Internet and / or with a laptop (see, for example , the LAP laptop shown schematically in Fig. 26) with a wireless network connection. In one respect, this will work about 20 feet away from the agitator, with the agitator working. The range can be extended with the use of a window in the computer compartment, or with the use of an antenna in the explosion-proof compartment with a glass dome. In addition, the technician can connect to a computer network with a network cable.
[0110] [0110] In certain aspects, the agitator in accordance with the present invention wirelessly connects to the Internet via an oil platform network connection. This allows for remote monitoring, troubleshooting and control. For example, if a platform has a problem, technical support will be contacted and will be able to view the status of the agitator, view the program variables, change settings and update the software remotely, from anywhere in the world, with an Internet connection .
[0111] [0111] The software on the agitator's computer, in certain aspects, has the ability to be updated for communication with other Drilling Equipment (EP) such as drilling chairs, Drawworks, rackers, mud control equipment and top drives. Optionally, local and / or remote interfaces with touch screens are provided. This will allow an operator to see more information about the agitator's status, including alarms, warnings, functionality checks and suggested changes to the agitator. Suggested changes to the agitator may include increasing or decreasing the sieve mesh, greasing the motor bearings, replacing sensors or checking the basket angle actuators.
[0112] [0112] In certain configurations, (see, for example, Figures 18 - 28) systems in accordance with the present invention provide tests, checks and intelligent diagnostics specific to the operational scenarios of the oil platforms, for operation of the vibrating separator and, in particular aspects, for operational scenarios of mud sieves that improve the safety of the oil platform and efficiency of oil field drilling operations, in certain particular aspects when applied to a shale agitator automatically operated by an electronic control system and / or computerized to ensure continuous and adequate system availability during well operations. In certain systems in accordance with the present invention, failures, performance degradations and / or predicted failures are reported to maintenance personnel who will perform additional diagnostics or send field personnel to replace or repair the systems when necessary.
[0113] [0113] The present invention provides a method and equipment for remotely monitoring, analyzing and affirmatively notifying appropriate personnel of problems and events associated with an oil recovery system comprising one or more, for example, hundreds of oil platforms over a wide range Geographical area. The present invention provides a monitoring and reporting system, referred to as the Functionality Control System. The present invention provides a variety of performance monitoring sensors on each oil platform in an oil recovery system, and, in certain respects, for each shale agitator on an oil platform. The results of the selected diagnoses run on each oil platform and / or on each agitator are reported to a central server. The central server automatically fills in the oil recovery system database and displays a report coded in red / yellow / green / gray for each platform and / or for an entire oil recovery system. The present invention also affirmatively warns appropriate personnel about the actions required to address events associated with an oil recovery system oil rig. The diagnostics made on each oil platform are configurable at the individual platform level. The central server does not need to change its reporting and display program when a functionality check changes on an oil rig. The present invention provides a dynamic state reporting protocol that allows the construction and display of a tree structure representing the entire state of an oil recovery system on a single screen. Preferably, top-level information is presented on a single screen and detailed information is presented when the user delves into other screens. Thus, the present invention allows quick visual confirmation of the Functionality Check of the system.
[0114] [0114] A Functionality Check is an automatic test running on the platform and monitoring something, such as, without limitation, one or more shale shakers, in relation to acceptable performance, indication of problems, etc. These tests can be applied to equipment, drilling processes or use by the specific Drilling Equipment operator, such as, without limitation, agitator (s). The results are then communicated to a central server located in a maintenance center, using a single protocol that allows automatic distribution and display of information, and / or directly from an agitator to an Internet interface. A test program on a platform can be modified and that change will automatically flow through communication, storage and display of Functionality Check Result data for that platform.
[0115] [0115] The web server based on maintenance center allows secure access to the results of the Functionality Check. The results are presented in the "inverted tree" mode with red / yellow / green / gray colors. The red color indicates failure of a test or signaling an event of interest, the yellow color indicates that the Functionality test found an abnormality that may need attention, green indicates completion of a successful test, and the gray color indicates an inability to drive. a test. The bottom node of the "inverted tree" contains the results of the Functionality Check. The result of a work case is successively taken to the next level, until it reaches the upper node (which in most cases is the oil rig, group of platforms or oil recovery system).
[0116] [0116] Each Functionality Check Result can be configured to generate a message (email, phone call, PDA, etc.) to alert one or more people in the event of a test failure. The data transfer protocol will be defined, so that other development groups or third parties can easily develop Functionality Check tests, generate results and feed the central server with information. The test results are transferred from the platform to the server using a new data protocol that dynamically defines the data structure, that is, the structure of the data node tree by the protocol naming convention. Thus, the results are simply stored and displayed using the structural definition provided in the communication protocol. This allows for extreme flexibility in defining new programs and results to be run and reported on oil platforms without requiring changes to the communication protocol, notification functions or display and storage functions on the central server. The lowest nodes of the tree structure contain test results. Each test enters the central server as a record containing node information with respect to where the information fits within the tree structure, an identifier for the test, a test result (red / yellow / green / gray) and data intermediates, such as error codes, operator input data, and test data description. Thus, no need for processing results occurs on the central server. The central server only archives and displays results and issues affirmative (acknowledged) and regular notifications as required.
[0117] [0117] Events or conditions can be configured for notification, and this way, once the event or condition occurs, and after it is configured for notification, a notification is sent to the designated person, reporting the condition event. A list of people can be associated with each event or condition of the oil rig. A notification can be sent to a cell phone, PDA or other electronic device. A notification can comprise a text, audio or video message to a user. A notification informs the platform status color code, via text, audio or video. A user can call the central server to check the status of an oil rig or oil recovery system. The returned status will be a notification message indicating that the platform is ok, or that a problem or condition of interest has occurred. In this way, Functionality Checks are different from alarms, although alarms (including alarms generated by previous or legacy systems) can be used as inputs to a Functionality Check, where alarms will be processed and considered by the Functionality Check, instead to send an alarm immediately to the people on the oil rig. A Functionality Check may indicate which part of the equipment is out of order and should be replaced in the near future, however crucial alarms can be set up by Functionality Checks to generate an immediate notification.
[0118] [0118] In certain respects, the present invention (and any and all steps and / or events described above, for any situation) is implemented as a set of instructions in a computer-readable medium, comprising ROM, RAM, CD ROM, Flash or any other computer-readable medium, currently known or unknown, which, when performed, causes a computer or similar system to implement the method and / or step (s) and / or events of systems and methods in accordance with the present invention, local, remote or both.
[0119] [0119] The present invention is described herein by the following example for use on drilling rigs, however, numerous other applications are considered suitable for use in association with the present invention.
[0120] [0120] The present invention provides a user interface, which, in one aspect, is preferably mounted on the existing floor structure of the platform and also offers a height-adjustable pedestal base for convenient choke operation. A wireless version is also provided.
[0121] [0121] The present invention supports bilateral real-time data communication, such as, for example, with RigSense and DAQ JVM from Varco International, Inc, and with other commercially available information systems. In one aspect, any sensors whose data is used by the present invention (for control and / or display) are directly connected to the present invention, including, without limitation, sensors from a shale shaker or agitators.
[0122] [0122] In one aspect, when the RigSense system is present in a configuration of the present invention, the RigSense system offers data archiving and expanded data display functionality for the present invention. The present invention provides a user interface integrated with other systems, such as the RigSense system, DAQ JVM and VICIS; Real-Time Well Control, specific supervisory control for well control tasks; and automated well control, which can be the entire process or subtasks selected. One of the main perceived impacts in relation to products and services where the integration and / or implementation of the present invention is made is the ability to take control and / or control the choke operation through a different intervention, so that the control is clearly exercised by users of other stations and by automated controllers.
[0123] [0123] A key factor for the efficient use and integration of the present invention into the operator's work environment is the provision, by the present invention, of manual controls for the user's high-frequency control actions, instead of display control consoles. touch sensitive. Additional automated functionality is provided, such as automatic pressure adjustment control for use in conjunction with the touchscreen, providing benefits to the control area, especially in emergency stations. In an alternative configuration, a touch screen user interface is provided.
[0124] [0124] In another configuration, the present invention is implemented as a set of instructions in a computer-readable medium, comprising RAM, CD ROM, Flash or any other computer-readable medium, currently known or unknown that, when executed, does the computer to implement a method of the present invention.
[0125] [0125] The present invention provides a method and equipment to remotely monitor, analyze, and affirm appropriate personnel remotely about problems and events of interest associated with an oil recovery system comprising one or more, for example, hundreds of oil platforms over a vast geographical area or an isolated platform. The present invention provides a monitoring and reporting system that is referred to as a Functionality Control System. The present invention provides a variety of Functionality Checks for performances, processes and equipment and equipment sensors on each oil platform in an oil recovery system. The present invention provides a dynamic state reporting protocol that allows the completion and display of a tree structure of nodes representing the situation of an entire oil recovery system or a simple oil platform on a simple screen. Thus, the present invention allows quick visual or auditory affirmation of a Functionality Check of the system.
[0126] [0126] Functionality checks are not the same as alarms. An alarm is an immediate notification to an operator that an unacceptable condition has been detected, requiring the operator to be aware of that condition, and generally requiring some action on the part of the operator. A Functionality Check can use alarms in its logic, but it is, by nature, different from an alarm. A Functionality check is more general and more diagnostic than an alarm and does not require immediate action, at least not on the oil rig. In the present invention, a problem is reported to a central server for maintenance personnel, for reporting and diagnosis. A Functionality Check can apply to any component or process of equipment, sensors, control systems, operator actions or control processes, etc.
[0127] [0127] The Functionality Control System comprises software containing test logic. The logic is configurable, so that inputs, outputs and logic can be selected by a user to test and observe any condition or event associated with an oil platform or an oil recovery system. The general system, in certain respects, comprises Functionality Checks being processed in real time on an oil rig computer and a communications network connecting the oil rig to a central server to move data from a platform or group of platforms for the server. The server displays the results hierarchically. The server sends commands, application programs and data to the platform, from the server.
[0128] [0128] The Functionality Control System of the present invention still comprises, in certain aspects, a central database filled with dynamic states reported from the oil platforms, comprising an oil recovery system. The present invention further comprises a web page viewer for efficient display of the Functionality Check Results associated with an oil recovery test, platform, area or system. The results of the web page can be displayed on a computer, cell phone, personal data assistant (PDA) or any other display device capable of receiving and displaying or otherwise alerting (such as, for example, by sound notification) a user about the state of the data. The preferred screen will be a color screen that allows the presentation of results in red / green / yellow / gray. The results may also be in audio, video or graphically encoded icons for severity reports, such as, for example, an audio message that reports a "green situation", "red situation" or "yellow situation" or one that displays an icon or graphic animation, or a video associated with the report, to demonstrate a Functionality Check severity report. The present invention allows deepening (that is, traversing a hierarchically structured data tree starting from the present node, towards any subordinate node or associated derivative branch), in a node tree that represents the diagnostic state, at the level of node or branch, to access additional information regarding a color-coded report.
[0129] [0129] The present invention also provides a notification system to immediately inform maintenance personnel of problems as needed, such as an email message to a cell phone or pager, or a computer pop up message. There is also a receipt confirmation function, which confirms that a notification message has been received and verified. Second and third notifications are sent when a first recipient does not verify a confirming statement within a configurable period of time. A severity report associated with a given problem is represented by an intermittent color, when it is not recognized, and remains in an intermittent color until the referred problem is solved and returns to the green or normal state. Severity reports, once recognized, change from intermittent to solid color. Reports that are recognized by a user may be transferred or reassigned to another user, either through administrative permission from a system supervisor, or by requesting permission to transfer to a second user, and receiving permission from the second user user. A system supervisor will also be able to display a list of users and severity reports handled by the user, that is, a list of recognized and ongoing severity reports assigned to a particular user, for viewing, and also to allow a distribution of the load of work, in order to facilitate reallocations to balance the workload.
[0130] [0130] A message can assign a work order to a specific group of severity reports. Once the work order is completed the system will check to see if the nodes associated with the work order have been released. The work order provides a secondary method for determining whether the nodes associated with a work order were released after the job was completed. The system administrator's software program will also be able to check the work order against node status for system verification.
[0131] [0131] The advantages offered to the customer of a preferred Functionality Control System is a substantial reduction in downtime, thanks to the ability that the Functionality Check of the present invention has to discover or anticipate problems and correct problems more quickly. , preferably before the customer realizes the problem has occurred. The present invention guarantees to the customer that the Functionality Control System is always in service and monitoring and reporting to the oil recovery system, twenty-four hours a day, seven days a week. A customer or system user will always be able to connect and confirm the status of the entire oil recovery system or of a simple platform, with a simple call to the central server or to a platform, and receive a situation report, that is, situation red, yellow, green or gray for the oil recovery system or for an individual platform, as requested. The present invention allows for more efficient use of operational service personnel. The present invention discovers and reports problems, potential problems, and alarms events of interest, which allows for quick response and recovery in the event of equipment or operator failures, real or potential, or the occurrence of a specific event. The present invention also helps to discover problems in their early stages, when problems are generally easier to solve, before catastrophic failures, thus creating less impact on the customer's oil recovery system or individual oil platform. Functionality Checks in accordance with the present invention provide a method and equipment for the provision of an application program that acts as a “set of eyes” always vigilant, watching over the entire oil recovery system or an individual platform, in order to ensure that everything is ok, that is, in operation.
[0132] [0132] In certain configurations, all the results of each oil rig in an oil recovery system or oil rig or individual equipment, such as, without limitation, an agitator or agitators, are the worst cases combined, so that the worst case severity report goes to the top of the report tree, and is reported as the status of the entire oil recovery system, oil platform (s), event of interest, process, or equipment under analysis. As discussed above, red is the worst case severity report, followed by the yellow severity report, with green being the least severity report. Gray indicates that no data is available. Thus, if one or more tests reporting a red state are received from an oil rig, the red state will override all the yellow and green state reports and the state of the platform and the entire oil recovery system where the oil resides. platform will be shown as red. Once the red report is confirmed, the yellow reports, if any, will appear and the status of the oil recovery system, platform or equipment being viewed will be shown as yellow, if a yellow report is in a node tree transmitted from of any oil platform in an oil recovery system. The status of a single platform will give rise to the worst case report, too, but located on the platform or on the individual platforms under investigation, unless grouped together. When grouped, the worst case status is reported for the entire group. For example, if three platforms are reporting, the following situation is possible: Platform one reports in red, platform 2 reports in yellow and platform 3 reports in green. The status of a group selected to include platforms 1, 2 and 3 will be red. The status of a group selected to include platforms 2 and 3 will be yellow. The status for a group selected to include only platform 3 will be green. Subsections within a platform can also be selected for a color-coded status report. Preferably, gray is "not answered". Generally, if the test is not conducted for any reason, the state will turn gray.
[0133] [0133] The present invention allows testing on the lower nodes of an inverted tree structure representing an oil recovery system, a single platform of the aforementioned, or an equipment of an oil platform, where the nodes carry the results to the top, for easy viewing and use. The present invention also provides a dynamic reporting protocol for data transfers from an oil platform to a central server where level identifiers are provided to transfer data and its structure in a single packet transfer, thus allowing the filling of a database. dynamic data and reporting from an oil rig. The results are presented on a web page or reported to cell phones, computers, pagers, personal data assistants or otherwise reported to the appropriate personnel. In a preferred configuration, reports are recognized by a first recipient or a second recipient is selected to receive the report when the first recipient does not check receipt, and so on, until a recipient receives and checks the report. Alternatively, multiple recipients can receive the notification simultaneously.
[0134] [0134] The present invention is automatically scalable and extensible due to the modular and dynamic nature of its design. Tests can be easily created, added or deleted and parameters can be added or modified in an oil rig equipment test or in a Functionality Check, without reprogramming or changing the database filling applications, data reporting and display data from the central server. The report can vary between broad coverage and specific coverage, that is, a state report can include data for an entire oil recovery system, comprising more than 100 oil platforms and / or specific data reports for a single oil platform of interest, simultaneously.
[0135] [0135] The present invention provides early warning of potential and actual failures, and also provides confirmation of performance and product use. A set of Functionality Checks and automated diagnostic tests are selected to be run in real time on an oil rig. The status obtained in the test is continuously reported through a communication link between the oil platform and the central server. The present invention provides criteria and analysis of equipment, process and use of equipment on an oil rig. The present invention monitors alarms and parameter limits to evaluate the necessary actions and notify the appropriate personnel in an affirmative manner.
[0136] [0136] The present invention provides real-time monitoring, with rapid response, as well as remote diagnosis of the automation and control systems in operation in the oil platforms forming sets of oil platforms or oil recovery systems, in order to obtain maximum platform performance, while maintaining optimal staffing. A maintenance center is connected to the oil platforms via an Internet-based network. System savvy makes data in real time and data logged from oil rigs available for examination and analysis at a central facility or in distributed locations. The website of the present invention provides access to the current operational status, as well as historical, operational and performance data for each of the platforms forming an oil recovery system.
[0137] [0137] The Functionality Check tests are configurable, so that new tests can be created, added or deleted, and parameters can be changed to run on an oil platform, without the need for programming. A simple user interface is provided, in which a user on the central server or on an oil rig can select a test, from an existing test library, or create a new test using a scripting language. A natural language or pseudo-language interface is provided, generating inputs and outputs for script definition and processing logic for tests. The script is compiled and sent to the platform for addition to existing Functionality Checks running on the platform. The user interface also allows modification, addition and deletion of parameters associated with a Functionality Check or test.
[0138] [0138] Notifications can be immediate messages, when a problem is detected, or warning notifications. The notification is sent to the specialized maintenance personnel associated with the central server, or it can be directed to a maintenance manager or the person in charge of local maintenance closest to the platform that needs maintenance. For each platform and for each type of problem, a specific person or category of maintenance personnel is assigned to receive notifications. Secondary and tertiary reserve personnel are designated as the recipient for each notification. Affirmative notifications need to be verified by the recipient, in order for the problem to be verified and someone has taken responsibility for the problem. If an affirmative notification is not recognized within a configurable period of time, then a secondary or tertiary recipient will be notified, until the problem is recognized. Reliability reports are generated by the present invention, showing performance summaries for oil platforms, comprising production time, response, problems detected and solutions provided. These reports provide an objective basis for formulating an assessment of the efficiency of the Functionality Verification system.
[0139] [0139] The results of a platform include the processed inputs of the platform. No processing is required from the central server, except display, storage and alerts to appropriate personnel. The Oil Platform Functionality Checks and tests are configurable, so that no programming is required to implement a new test or changes to the logic or parameters of an existing test. A field engineer or central server staff will be able to add new tests, without having to ask a user to make changes to the schedule. The present invention provides a local or remote user interface that offers a simple interface for describing a test and logic. The interface comprises iconic presentation, pseudo-language, script or a natural language interface to describe input (s), processing logic and output (s) of a test. The user interface interprets user input and converts it to a scripting language. The scripting language is compiled and sent to the platform where the new test or the extended test is to be performed. The new test is added to a test library, from which it can be selected by a user for application on the platform. The test modules can be deleted, added, their parameters changed and updated from the oil platform, the central server or by a remote user, using an electronic remote access device.
[0140] [0140] With reference now to Figure 18, a preferred embodiment of the present invention is shown, illustrating an overall view 200 of all platforms forming an oil recovery system. As shown in Fig. 18, a map indicates the geographic location of the platforms in the system of interest. A web page display is presented on a personal computer or PDA. The web page generated by the central server presents a geographical view of an oil recovery system. In Figure 18, platform number 563 (702) and platform number 569 (707) are shown with a red status, indicating that a condition or event of interest report occurred on platforms number 563 and number 569. Platform number 569 ( 706) is in Canada and platform number 563 (711) is in the United States. Platform number 571 (709) is in yellow state and platform number 567 (708) is in gray state. All other platforms, as shown in Figure 18, are in a green state. When a user of the system clicks on platform number 569 (707) or in the Canadian region, the display in Figure 19 appears. Figure 19 shows the Canadian region, which includes platform number 569. Note that platform number 570, with green status, is now displayed on the most detailed display of the Canadian region. The geographic green status indicator for platform number 570 has been suppressed and is not shown on the larger display in Figure 18, so that the red, more severe state of platform number 569 becomes immediately visible and evident on the display in Fig. 18.
[0141] [0141] Once a user implicitly checks the red status of platform number 569 by clicking on platform number 569, the present invention will display the less severe state of platform number 570. Thus, the more severe state of platform number 569 goes up on the display geographic and is displayed first, at a higher level, in the geographic display hierarchy. Note that the green status indicator on platform number 570, however, is shown on panel 704 of Figure 18 and Figure 19. Thus, the present invention features a hybrid display where all Functionality Check Results are available on panel 704, but worst case results are shown on the geographic displays in Figure 18 and Figure 19.
[0142] [0142] With reference now to Figure 20, the status indicator 724 in Figure 20 for platform number 569 is shown when a user clicks on platform number 569 in Figure 18 or Figure 19. Figure 20 illustrates that the component of the platform number 569, "RigSense", has a red indicator. The Magnifier 722 icon, shown adjacent to the red indicator 730 indicates that more information is available regarding the red indicator 730. Note that there are also additional panel displays 716 and 718, which are configurable, performing additional informational functions. A summary panel 720 is displayed for platform number 569. The status summary panel contains operator reports from the oil platform. These operator reports are useful for diagnosing the status and formulating an action or notification plan. An AutoDriller status panel is also displayed. Note that the Weight on Bit (WOB) indicator 717 is red in the AutoDriller status panel. A panel of adjustable drill parameters 718 is also displayed.
[0143] [0143] With reference now to Figure 21 A, continuing with platform number 569, a click on the red RigSense status indicator in Figure 20 will bring up the RigSense 740 system panel status display, as shown in Figure 21A. Note that device message block 743 may contain a part number to expedite the repair of a failure, as reported. The specific part number and / or drawing number needed to perform a particular repair associated with a particular problem or severity report can be difficult to find, in a vast stock of parts, part numbers and drawings associated with a particular failure . Otherwise, the recipient of a failure report would need to search, using keywords, across a vast stock of parts, part numbers and drawings associated with a particular failure. In addition, the user may not be familiar with the numbering system of a specific distributor and thus the provision of the part number is a valuable expedient for the detection and correction of problems.
[0144] [0144] Figure 21A shows that the state of the sensor group 742 device is red, with a Magnifier Icon 746 indicating that more information is available for the red state of the sensor group 742 device. alternate configuration, as shown in Figure 21B, a pop-up message 746a appears along with the Magnifier, saying "Click on the Magnifier for more details". A click on the Magnifier 746 of the sensor group device 746 will bring up the display 750 in Figure 22, showing the detailed status of the sensor group device. Note that there are two red indicators shown in Fig. 22 for device states, in the sensor group, as follows: "Sensor Pump 3 Stroke Count" 756 and "Hookload Sensor" 754. Note that the red Pump 3 device status indicator has an informational comment 752 in the operations column of the display in Figure 22, saying "Intermittent Loss of Signal". The Sensor Hookload's red device status indicator has an adjacent Magnifying Glass Icon 758 with a message indicating that more information will be available for the Hookload Sensor's device status by clicking on the Magnifying Glass Icon. Clicking the Magnifier 758 indicator on the Hookload Sensor will bring up the Hookload Sensor 766 panel in Figure 23, which shows that the device name "Barrier" 760 has a red device status indicator 762. The status of Barrier's red device displays an Operational 764 message, saying, "Excessive ground current". Each colored indicator and the respective operational message shown on the preferred displays illustrated in Figures 1 8 - 2 3 appeared in line with the Functionality Check performed on the oil platform and sent to the server in the structured protocol of the present invention.
[0145] [0145] Figure 24 illustrates a Driller Adjustable parameter display 710 with two red indicators showing that Drill Low Set Point 712 and Upper Set Point 714 are Outside Range. The Drilling Tuning parameter panel 716 is also displayed. Both panels indicate a present value, “changed” indicator and “out of limits” indicator for each parameter shown in the respective panels in Figure 24. The display in Figure 24 is an alternative tabular display for “platform state” of a individual platform. Figure 25 illustrates a configuration or status panel for adjustable drill parameters 810 for platforms number 178-189. The display in Figure 25 is an alternative tabular display for platform status for a plurality of platforms, such as, for example, platforms 178-189. Referring now to Figure 26, an 801 data acquisition system is shown in an oil rig environment connected to a plurality of legacy sensors or Functionality Verification ("SENSORS") which, in certain respects, includes the sensors of an agitator or agitators, which collect data from the group of sensors that monitors the equipment, parameters and processes of the platform. The data acquisition system 801 sends the acquired data from the sensors to a computer 804 where it runs the preferred Functionality Check application of the present invention. The application of the present invention performs Functionality Checks logic on the acquired data and reports the results, in the structured protocol, to a user, via satellite 806 or through some other form of electronic communication. A user can monitor the status of the Functionality check and receive notifications via an 808 electronic receiver, 807 diagnostic station, or mobile, in an 805 field maintenance vehicle. Alternatively, the agitator (s) can maintain direct communication from the CPR shaker computer with the data transmission system.
[0146] [0146] The present invention is also useful for Process Monitoring, that is, to determine whether the equipment is being used properly, to perform a designated process. For example, if the platform operators are making use of override during a certain system state indicative of a certain process that should be running automatically, instead of being manually operated, the present invention can perform a verification of Functionality to detect this event of interest and report it to the central server. The knowledge of this occurrence will allow the personnel of the central server to be able to stop and correct the inappropriate action of the operators. In addition, the test to detect inadequate cancellation remains in the system, so that if new operators re-create the problem, or if trained operators reuse manual cancellation inappropriately, central server personnel will be notified that the problem can be addressed again. In this way, the Functionality Control System builds a cumulative basis of operational checks to ensure that a process on a platform or in an oil recovery system operates optimally.
[0147] [0147] Referring now to Figure 27, which is an illustration of a preferred Functionality Control System reporting Functionality checks for multiple equipment, processes or systems from multiple oil platforms to multiple users. It should be understood that any controller or equipment associated with any equipment, device or equipment can be employed for the system, as shown in Figure 27, but the specific item shown schematically is a controller and / or a stirrer computer. As shown in one aspect, the controller and / or computer of the agitator is in communication with a Rig Health Commander, a Health Check Engine, and a user. Optionally, the controller and / or computer of the agitator may be in direct communication, through the Internet or similar network, with another entity, device and / or user.
[0148] [0148] Referring now to Figure 28, the test results are reported to the central server in a special protocol that contains data from Functionality verification results and describes the way the data is constructed so that it can be inserted into a structure logical data or in a tree format and then displayed. Note that the root node 810, which is usually an oil rig, has the designation "00". The first level of nodes 812, 813 etc. below the root node are called Aa, Ab, Ac, Ad, etc. Each subsequent layer of nodes is named after the node name “parent,” followed by the designation of the current node. For example, as shown in Figure 28, for platform number 569, the root node 810 is called "00", the first level of "child" nodes under the root node is called Aa 812 and Ac 813. The "children" of the node Aa 812 are called AaBa 814, AaBd 1116, AaBe 818 and AaBf 820, as shown. The "children" of the AaBa "child" node are called AaBaCl 822, AaBaC2 824, AaBaC3 826 and AaBaC4 828. The "children" of the AaBaC5 830 node are called AaBaC5Dg 832, AaBaC5Dp 834, AaBaCa5AD5A8AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAU be added to platform number 569 and the Functionality Check status could be reported under the node AaBaC5Dx 840.
[0149] [0149] Changes to Functionality Checks running on any or all platforms do not require changes to the display or database filling, as the preferred communication protocol defines the database layout and the display layout. The leaf nodes in the tree structure represent Functionality Check Results. Each node contains a test identifier, a test result (red / yellow / green / gray), intermediate data, data entered by the user and test description. Comments for error detection and correction are provided on the central server based on the reported errors. Test error codes are added to the node, so that the messages associated with the error codes are displayed to the appropriate user. Alternatively, information related to the detection and correction of errors and other information can also be generated and attached to the test results, at the platform location. Thus, no processing to determine a platform state is done on the central server. Notifications are sent when deemed necessary by the application. The notification logic is configurable by maintenance personnel on the central server or on the oil rig. The notification logic determines the sending of notifications when an event occurs and that the event is selected for reporting in the form of notification to a user. The notification logic and a list of appropriate notification recipients in order of priority, that is, who should be contacted first, are maintained on the central server. The event can be a report on the state of an equipment, the execution of a process or an operational item. A user can access the central server of the present invention to obtain a real-time report on the status of an oil platform or multiple oil platforms. The requesting user will receive a severity report message indicating the status of the platform, such as, for example, "normal" or "red / yellow / green / gray".
[0150] [0150] Figures 29-32B illustrate computer screen displays for a configuration of the control system for agitators and methods for respective use in accordance with the present invention.
[0151] [0151] Figure 29 shows a screen provided by a server, such as, for example, a web server on a shaker computer (such as, for example, 530, 630 computers and the shale shaker computer controller. of Figure 27). When this computer is connected and communicating with a platform control system, interfaces to the platform control system are identified as "Alarms & Events", "Diagnostics" and "Documentation" [ Documentation]. From the "General" column, an operator can go to any of the five related options. Selecting "Debug Monitor" will take you to a screen like the one in Figures 32A and 32B that allows a user to monitor and modify agitator program variables. Selecting "Administration" will take you to a screen like the one in Figure 30. "Array Manipulator" will take you to a screen that displays the set of input / output channels. "Software versions" will take you to a screen that displays the current software version "Log Manager / Viewer" will take you to a screen that allows the user to view and delete log files from the system.
[0152] [0152] The screen in Figure 30 (displayed when the "Debug Monitor" line in Figure 29 is clicked) illustrates a variety of checks and administrative tasks that can be done against the agitator's computer. "Restart JVM" is selected to restart the computer's operating system software on the agitator's computer. The agitator control program can be interrupted by selecting "Stop Controller". This screen allows a user to select which parameters and variables will be displayed (such as, for example, on screens such as those shown in Figs. 32A and 32B). The general state of the agitator is displayed by selecting "ControlStation". The selection of "Timer" will display variables and states of timers. The "ai" screen will display variables and states of analog inputs, such as, for example, the distance measured by ultrasonic transducers to the fluid in the screens. Variables and states of the Controller are displayed by selecting "Controller." Variables and states of digital inputs [such as, for example, signals from the agitator frequency converter] and those actuated by means of push buttons and user keys (such as, for example, those in Figure 14) are displayed by selecting "di." Variables of digital outputs, such as, for example, valve opening and closing signals and signals for a frequency converter, so that it starts operating fast or normal operation, are displayed by selecting “dq.” Parameters and variables of the protocol used to send and receive information will be displayed by selecting “modbus”.
