    CROSS REFERENCE WITH RELATED APPLICATIONS [001] This application claims the benefit of the filing date of US Patent Application Serial No. 12 / 905,715 filed on October 15, 2010, which is partly a continuation and claims the benefit of the Application for US Patent No. 12 / 645,300 filed December 22, 2009, for DOWNHOLE-ADJUSTABLE FLOW CONTROL DEVICE FOR CONTROLLING FLOW OF A FLUID INTO A WELLBORE.
    BACKGROUND OF THE DESCRIPTION
    FIELD OF THE INVENTION [002] The description generally refers to apparatus and methods for controlling the flow of fluid from underground formations in a production column in a well.
    DESCRIPTION OF THE RELATED TECHNIQUE [003] Hydrocarbons such as oil and gas are recovered from an underground formation using a well or well drilled into the formation. In some cases, the well is completed by placing a liner along the length of the well and drilling the casing adjacent to each production zone (hydrocarbon support zone) to extract fluids (such as oil and gas) from the associated production zone. In other cases, the well may be an open hole, that is, without a coating. One or more inflow control devices are placed in the well to control the flow of fluid within the well. These flow control devices and production zones are generally separated by shutters installed between them. The fluid from each production zone that enters the well is drawn into a tubular that moves to the surface. It is desirable to have a substantially uniform fluid flow throughout the
    Petition 870190035031, of 12/12/2019, p. 6/37
    2/23 production. Uneven drainage can result in undesirable conditions such as the invasion of a gas cone or water cone. In the case of an oil production well, for example, a gas cone can cause an influx of gas into the well that could significantly reduce oil production. Similarly, the water cone can cause an influx of water into the oil production flow that reduces the quantity and quality of the oil produced.
    [004] A deviated or horizontal well is often drilled in a production area to extract fluid from it. Various inflow control devices are placed spaced along such a well to drain the formation fluid or inject a fluid into the formation. The forming fluid often contains an oil layer, a water layer below the oil and a gas layer above the oil. For production wells, the horizontal well is typically placed above the water layer. The boundary layers of oil, water and gas may not be uniform over the entire length of the horizontal well. Also, certain properties of the formation, such as porosity and permeability, may not be the same over the length of the well. Therefore, the fluid between the formation and the well may not flow evenly through the inflow control devices. For production well holes, it is desirable to have a relatively uniform flow of production fluid within the well and also to inhibit the flow of water and gas through each inflow control device. Passive inflow control devices are commonly used to control the flow into the well. Such inflow control devices are determined to allow a certain flow rate through them and are installed in the well and are not designed or configured for downhole adjustments. Sometimes it is desirable to change the flow rate for a particular zone. This may be because a particular area has started producing a flu
    Petition 870190035031, of 12/12/2019, p. 7/37
    3/23 undesirable acid, such as water or gas, or the inflow control device has clogged or deteriorated and the current adjustment is not adequate, etc. to change the flow rate through such passive inflow control devices, the production column is removed, which is very expensive and time consuming.
    [005] Therefore, there is a need for adjustable inflow control devices that can be adjusted at the bottom of a borehole.
    SUMMARY [006] In one aspect, an adjustable downhole flow control device is provided which in one embodiment includes a control device with a direct flow region configured to receive formation fluid in an inflow region and discharge the fluid received in a flow outlet region and an adjustment device configured to adjust the flow of fluid through the direct flow region to a selected level, the adjustment device including a coupling element configured to be coupled to a coupling device external adapted to move the coupling element to make the adjustment device alternate the fluid flow to a desired level.
    [007] In another aspect, an apparatus for controlling the flow is described which in one embodiment may include a passive inflow control device configured to receive fluid from a formation and discharge the received fluid to a flow outlet region, a device adjustment device configured to adjust the fluid flow through the inflow control device, the adjustment device including a coupling element and an engagement device configured to engage the coupling element to operate the adjustment device to adjust the fluid flow through the inflow control device.

DETAILED DESCRIPTION OF THE DESCRIPTION [0020] The present description refers to the apparatus and methods for controlling the flow of formation fluids in a well. The present description provides certain exemplary drawings to describe certain modalities of the apparatus and method which are to be considered as exemplifying the principles described here and are not intended to limit the concepts and description to the illustrated and described modalities.
    [0021] Referring initially to figure 1, an exemplary production well system 100 is shown which includes a pole hole 110 drilled through a land formation 112 and in a pair of production zones or reservoirs 114, 116. The well 110 is shown coated with a coating having a number of perforations 118 that penetrate and extend within the forming production zones
    Petition 870190035031, of 12/12/2019, p. 10/37
    6/23
    114, 116 so that production fluids can flow from production zones 114, 116 into well 110. Exemplary well 110 is shown including a vertical section 110a and a substantially horizontal section 110b. Well 110 includes a production column (or production assembly) 120 that includes a tube (also referred to as the base tube) 122 that extends downwardly from a wellhead 124 on the surface 126 of well 110. The production column 20 defines an internal axial hole 128 along its length. An annular crown 130 is defined between the production column 120 and the well casing. Production column 120 is shown including a generally horizontal portion 132 that extends along the bypass leg or section 110b of well 110. Production devices 134 are positioned at selected locations along production column 120. Optionally, each production device 134 can be isolated within well 110 by a pair of plugging devices 136. Although only two production devices 134 are shown along the horizontal part 132, a large number of such production devices can be arranged along the part horizontal 132.
    [0022] Each production device 134 includes an adjustable downhole flow control device 138 made in accordance with an embodiment of the description to govern one or more aspects of the flow of one or more fluids from the production zones to the flow column. production 120. The downhole adjustable flow control device 138 may have a number of alternative structural aspects which provide selective operation and controlled fluid flow therethrough. As used herein, the term fluid or fluids includes liquids, gases, hydrocarbons, multiphase fluids, mixtures of two or more fluids, water and fluids injected from the surface, such as water. Additionally, references to water must be interpreted in a
    Petition 870190035031, of 12/12/2019, p. 11/37
    7/23 to also include water-based fluids; for example, saline or salt water.
    [0023] Underwater formations typically contain water or saline solution with oil and gas. Water may be present below an oil and gas support zone may be present above that zone. A horizontal well, such as section 110b, is typically drilled through a production zone, such as production zone 116, and can extend more than 1,524 m in length. Since the well has been in production for a period of time, water can flow in some of the production devices 134. The amount and time of inlet water flow can vary over the length of the production zone. It is desirable to have flow control devices that can be adjusted in a downhole when desired to control the flow of unwanted fluids and / or change the flow through it to equalize the flow. The downhole adjustable device can also be designed to automatically restrict the amount of water flow through the downhole adjustable flow control device.
    [0024] Figure 2 shows an isometric view of an embodiment of a part of an exemplary multi-channel inflow control device 200 that can be used in the drilling column and well described here. The flow control device 200 can be included in an adjustable downhole flow control device 138 to control the flow of fluids from a reservoir into a production column. The production device 134 can include a filtering device to reduce the amount and size of particulates captured in the fluids and the inflow control device 200 that controls the total drainage rate of the forming fluid into the well. As shown, the inflow control device 200 is shown to include several sections of structural flow
    Petition 870190035031, of 12/12/2019, p. 12/37
    8/23 tourals 220a, 220b, 220c and 220d formed around a tubular element 202, each section defining a flow channel or flow path. Each section can be configured to create a predetermined pressure drop to control a flow rate of the formation production fluid into the well pipe. One or more of these flow paths or sections can be obstructed or independent (not in hydraulic communication with another section) in order to provide a selected or specified pressure drop across such sections. The flow of fluid through a particular section can be controlled by closing holes 238 provided for the selected flow section.
    [0025] As discussed below, a tubular element can join the holes and thus expose one or more selected holes, depending on parameters and conditions of the surrounding formation. As shown, the total pressure drop through the inflow control device 200 is the sum of the pressure drops created by each active section. Structural flow sections 220a-220d can also be referred to as flow channels or direct flow regions. To simplify the description of the inflow control device 200, the flow control through each channel is described with reference to channel 220a. Channel 220a is shown to include a flow aids region or area 212 (also referred to as a first flow region) and an inflow region 210 (also referred to as a second flow region). The forming fluid enters channel 220a within inflow region 210 and exits the channel via flow outlet region 212. Channel 220a creates a pressure drop by channeling fluid flowing through a direct flow region 230, which it may include one or more flow stages or conduits, such as stages 232a, 232b, 232c and 232d. Each section can include any desired number of stages. Also, in aspects, each channel in the influence control device
    Petition 870190035031, of 12/12/2019, p. 13/37
    9/23 x 200 can include a different number of stages. In another aspect, each channel or stage can be configured to provide an independent flow path between the inflow region and the outflow region. Some or all channels 220a-200d can be substantially hydraulically isolated from each other. That is, the flow through the channels and through the device 200 can be considered in parallel instead of in series. Thus, a production device 134 can allow flow through a selected channel while partially or totally blocking flow in the other channels. The inflow control device 200 blocks one or more channels without substantially affecting the flow through another channel. It should be understood that the term parallel is used in the functional sense instead of suggesting a particular structure or physical configuration.
    [0026] Still referring to figure 2, additional details of the multi-channel flow element 200 are shown which creates a pressure drop leading the flow flowing through one or more of the channels 220a-220d. Each of the channels 220a-220d can be formed along a wall of a base tubular or mandrel 202 and include structural aspects configured to control the flow in a predetermined manner. While not required, channels 220a-220d can be aligned in a parallel and longitudinal way along the long axis of mandrel 202. Each channel can have an end in fluid communication with the well tubular flow hole (shown in figures 3- 8) and a second end in fluid communication with the annular space or annular crown separating the flow control device 200 and the formation. In general, channels 220a-220d can be separated from each other, for example, in the region between their respective inlet and outlet stream regions.
    [0027] In modalities, channel 220a can be arranged as a labyrinth structure that forms a tortuous flow path or
    Petition 870190035031, of 12/12/2019, p. 14/37
    Surrounding 10/23 for the fluid to flow through it. In one embodiment, each stage 232a-232d of channel 222a can respectively include a chamber 242a-242d. Openings 244a-244d hydraulically connect chambers 242a-242d in a serial manner. In the exemplary configuration of channel 220a, the forming fluid enters the inflow region 210 and discharges into the first chamber 242a through the orifice or opening 244a. The fluid then moves along a tortuous path 252a and discharges into the second chamber 242b through orifice 244b and so on. Each of the orifices 244a-244d exhibits a certain pressure drop across the orifice which is a function of the configuration of the chambers on each side of the orifice, the deviation between the orifices associated with them and the size of each orifice. The stage configuration and the structure inside determine the tortuosity and friction of the fluid flow in each particular chamber, as described here. Different stages on a particular channel can be configured to provide different pressure drops. The chambers can be configured in any desired configuration based on the principles, method and other modalities described here. In embodiments, the multi-channel flow element 200 can provide various flow paths from the formation into the tubular.
    [0028] As discussed below, the downhole adjustable flow control device can be configured to allow adjustment of the fluid path through the multi-channel flow element, thereby customizing the device based on the formation and flow characteristics of fluid. The channel or flow path can be selected based on the content of forming fluid or other measured parameters. In one aspect, each stage in the inflow control device 200 can have the same physical dimensions. In another aspect, the radial distance, orifice deviation and orifice size can be chosen to provide a desired tortuosity of
    Petition 870190035031, of 12/12/2019, p. 15/37
    11/23 so that the pressure drop will be a function of the viscosity or density of the fluid. In one embodiment, a multi-channel flow element may exhibit a relatively high percentage drop in pressure drop for low viscosity fluid (up to about 10cP) and a substantially constant pressure drop for fluids in a relatively higher viscosity range ( from about 10cP to 180cP). Although the inflow control device 200 is described as a multi-channel device, the inflow control device used in a downhole adjustable flow control device can include any suitable device, including, but not limited to, the device orifice type, helical device and a hybrid device.
    [0029] Figure 3A is an isometric view of a well-bottomed flow control device 300 over a tubular element 302 according to one embodiment of the description. Figure 3B is a sectional view of the tubular 302 and adjustable flow control device 302. Figures 3A and 3B represent the adjustable flow control device 300 in a first position, the position of which, for example, can be determined before unfold the flow control device 300 in the well. The flow control device 300 is shown to include a multi-channel flow element 304 (also referred to as the inflow control device) and the adjustment device 305. The first position of the adjustment device 305 corresponds to a channel selected from the multichannel flow element 304. In one aspect, the multichannel flow element 304 includes several flow channels, each channel having a different flow resistance. In one embodiment, the flow resistance for each channel can be configured to restrict a flow of a selected fluid, such as gas or water, within the 302 tubular. As shown, the multi-channel flow element 304 is
    Petition 870190035031, of 12/12/2019, p. 16/37
    12/23 configured to allow fluid flow through a channel that includes a series of stages 306, a flow orifice 307 and tubular 302. In aspects, flow orifice 307 is located in a grooved portion 309 of tubular 302 , thereby allowing fluid flow from all orifices 307, if covered or uncovered by a rotationally indexed element 308. In one aspect, four flow orifices are located circumferentially, at 90 degrees with respect to each other, around the part with grooves 309. The rotationally indexed element 308 includes a recessed part 310 that exposes the flow hole 307. The rotationally indexed element 308 includes a rail 312 (also referred to as a J slot or guide rail) and a pin 314 (also referred to as pin J or guide pin) that control the rotational movement of the rotationally indexed element 308. In one aspect, there may be several pins 314 positioned with the rail 312 to ensure r stability during movement of the rotationally indexed element 308. In aspects, rail 312 is a standardized opening in the element that allows rotational and axial movement to adjust the flow of fluid through the flow control device 302. In one embodiment, the axial movement of the components located within the tubular 302 can adjust the rotationally indexed element 308 to cause fluid flow through a selected channel of the multi-channel flow element 304.
    [0030] The adjustment device 305 includes the rotationally indexed element 308, tilt element 320 and the guide sleeve 316, each located outside the tubular 302. The guide sleeve 316 is coupled to the rotationally indexed element 308, which allows movement axial 317 of the tubular 302 and the sleeve 316, while allowing the rotational movement independent of the components, the guide sleeve 316 is also coupled to the tilting element 320, such as a spring, which repeats 870190035031, from 12/04/2019, p. . 17/37
    13/23 is the axial movement 317 when compressed. In one aspect, the tilt member 320 is fixedly attached to the tubular 302 at the end opposite the guide sleeve. In the embodiment shown, the luvaguia 316 is coupled to a guide pin 322 located in a slot. The guide pin 322 controls the axial range of movement of the guide sleeve 316 and the tilt element 320. An internal element (also referred to as a coupling element, a coupling device or coupling tool), such as a clamp 324 , is located within the tubular 300 and includes protrusions 326 configured to selectively engage a bypass sleeve 328 which is a part of or coupled to the guide sleeve 316. The bypass sleeve 328 can also be referred to as a coupling element. As discussed below in figures 4A and 4B, protrusions 326 can engage deviation sleeve 328 when the clamp 324 moves axially in the direction 317 within the tubular 300. The clamp 324 can be any suitable element or tool configured to move axially within the tubular 300 and cause movement of the adjustable flow control device 302. The clamp 324 includes axial elements 332 separated by slits, where the axial elements 332 are configured to orient or press away from the tubular axis and against the inner surface of the tubular 302. Consequently, a wire thread tool or coiled tubing can be used to move the clamp 324 axially 317 within the tubular 302. The clamp 324 can selectively engage and disengage the components within the tubular 302 to cause movement of the rotationally indexed element 308 and other components of the adjustable flow control device 300.
    [0031] Figures 4A and 4B show a side view and a sectional view, respectively, of the tubular 302 and the adjustable flow control device 300 in transition between the channel flow positions. In aspects, the adjustable flow control device 300 can
    Petition 870190035031, of 12/12/2019, p. 18/37
    14/23 have any number of flow positions. As shown, the adjustable flow control device 300 is in transition between the position in figures 3A and 3B and the position in figures 5A and 5B. In one aspect, a wireline tool or slickline tool can be used to move the clamp 324 in the direction 317, in which the clamp 324 engages the bypass sleeve 328. When engaging the inside of the bypass sleeve 328, the clamp 324 does the tilt element 3290 compresses and the rotationally indexed element 308 moves in the direction 317. When the rotationally indexed element 308 moves in the direction of 330, the rail 312 moves around the pin 314 to make the element rotationally move. As shown, the pin is in position 400 of the rail 312 and the rotationally indexed element 308 is in transition between the first position and the second position, where the pin 314 is located in positions 402 and 404, respectively. The clamp protrusions 326 can remain engaged with the deflection sleeve 328 until the protrusions 326 are pressed axially (318) and inwardly as by a release glove 406 located inside the tubular 300.
    [0032] After releasing the protrusions 326 from the diverter sleeve 328, the wireline tool continues to move the clamp 324 towards the bottom of the shaft in the 330 direction. Releasing the clamp 324 causes the slope element 320 to expand, making the element rotationally indexed 308 and the guide sleeve 316 moves towards 408 to the second position. The second position causes fluid to flow through a second channel of the multi-channel flow element 304 while pin 314 is at position 404 of rail 312. Figures 5A and 5B show a side view and a section view, respectively, of the adjustable flow control device 300 in the second position. As shown, the adjustable flow control device 300 allows fluid flow through channel 500 of the flow control element
    Petition 870190035031, of 12/12/2019, p. 19/37
    15/23 of multiple channels in the second position. Consequently, the rotationally indexed element 308 is rotated to prevent flow and fluid through other flow channels, including channel 502. The tilt element 320 is completely expanded, thereby pressing the guide pin 322 to a limit of the slit pin. When the clamp 324 moves in the direction 330 and releases the diverter sleeve 328, the pin 314 of the rotationally indexed element 308 moves to the position 404 of the rail 312. The recessed part 310 of the element 308 is then aligned to allow the flow of fluid from channel 500 into flow port 307.
    [0033] Figures 3A to 5B show the movement of the adjustable flow control device 300 between two positions, where each position causes the forming fluid to flow through a different channel from the multi-channel flow element 304 and into the tubular 302. In aspects, the multi-channel flow element 304 includes several channels configured to allow selected fluids to flow into the tubular 302 while restricting the flow of other fluids. A wireline tool or other suitable device can be used to move the inner element or clamp 324 into the tubular 302 to adjust the adjustable flow control device 302. The process shown in figures 3A to 5B can be repeated as many times as desired to place the adjustable flow control device 300 in a selected position.
    [0034] In another embodiment, an electromagnetic or mechanical electrical device can be used to adjust the position of a flow control device, in which a wireline or slickline can communicate command signals to control the flow of fluid within the tubular. Figure 6A is a sectional view of an embodiment of a tubular 602 and an adjustable flow control device 600 in a first position. As shown, the flow control device
    Petition 870190035031, of 12/12/2019, p. 20/37
    16/23 x adjustable 600 is shown before deflecting or adjusting the flow path within tubular 602. Adjustable flow control device 600 includes a multilayer flow element 604 that contains a series of stages 606. Stages 606 allow fluid to flow through flow hole 607 within tubular 602. In one embodiment, several flow holes 607 are positioned circumferentially around tubular 600. An adjustment device 605 includes a rotationally indexed element 608 with a recessed part 610 which selectively exposes one of the flow holes 607. The rotationally indexed element 608 includes a rail 612n and pin 614 that cooperatively control the movement of the rotationally indexed element 608. In one aspect, several pins 614 can be positioned within the rail 612 to ensure stability during rotational movement. In aspects, rail 612 is a standardized opening in the element that allows rotational and axial movement to adjust the flow of fluid through the adjustable flow control device 600.
    [0035] The adjustment device 605 also includes an inclination element 620 and guide sleeve 616, each located outside the tubular 602. The guide sleeve 616 is coupled to the rotationally indexed element 608 for axial movement 617 as well as the rotational movement independent of the components with respect to each other. A magnetic element 618 is positioned on the guide sleeve 616 to allow magnetic coupling to the components within the tubular 602. In one aspect, several magnetic elements 618 can be positioned circumferentially on the sleeve 616. As illustrated, the guide sleeve 616 is also coupled to a tilting element 620, such as a spring, that resists axial movement 617 when compressed. The tilt element 620 is attached to the tubular 602 at the end opposite the guide sleeve 616. As shown, pin 614 is positioned close to a
    Petition 870190035031, of 12/12/2019, p. 21/37
    17/23 first end of rail 612 (or axial downhole end). In other respects, the guide sleeve 616 can be metallic or magnetized, thereby providing a coupling force for a magnet within the tubular 600.
    [0036] An intervention column 622 can be used to conduct a well bottom magnet assembly 624 within the tubular 600. The magnet assembly 624 may include a suitable electromagnet configured to use electrical current to generate a magnetic field. The magnet assembly 624 can generate a magnetic field to make a coupling with the metallic element (s) 618. The current is supplied in the magnet assembly 624 by a suitable power source 626, which can be positioned at, on or adjacent to a wireline or spiral pipe. The magnet assembly 624 can be selectively driven when the intervention column 622 moves axially in the direction 617 inside the tubular 600 to cause the guide sleeve 616 to move. For example, the magnetic assembly 624 can generate a magnetic field to allow a coupling on the magnetic element (s) 618 when the column 622 moves axially 617 down a well, thereby causing the guide sleeve 616 to move axially 617. The magnetic coupling between the magnet assembly 624 and the magnetic elements 618 is sufficient strength to maintain the coupling to overcome the spring force of the tilting element 620 when the guide sleeve 616 moves axially 617. In one aspect, the metal element (s) 614 can be a magnet to provide sufficient strength in one coupling between the element and the magnet assembly 624. The magnet assembly 624 can include several magnets spaced circumferentially around the assembly, where each electromagnet is configured o for coupling to a corresponding metal element 614. As shown, the wireline components and the magnet assembly 624 can be used to move the guide sleeve 616 and the element

    18/23 rotationally indexed 608, axially 617. Additionally, the axial movement 617 of the magnet assembly 624, while magnetically coupled to the guide sleeve 616, causes the rotational movement of the rotationally indexed element 608, thereby adjusting the flow path through the multi-channel flow element 604. [0037] It should be noted that components positioned outside the tubular 602 (figures 6A-6C), including the adjustable flow control device 600, are substantially similar to those shown in figures 3A-5B. Specifically, in aspects, the illustration of figures 6A, 6B and 6C correspond to that of figures 3A, 4A and 5A. The illustrated mechanisms show different devices or tools located within the tubular to adjust the adjustable flow control devices. In other embodiments, the components, including the multi-channel flow element 604 and the rotationally indexed element 608, may include different application-specific configurations and components depending on cost, performance and other considerations. In addition, the power source 626 may also include one or more sensor packages, including, but not limited to, sensors for making measurements related to flow rate, fluid composition, fluid density, temperature, pressure, water cut , oil-gas ratio and vibration. In one embodiment, measurements are processed by a processor using a program and memory, and you can use selected parameters based on measurements to change position and flow through the 602 adjustable flow control device.
    [0038] Figure 6B is a sectional view of tubular 602 and adjustable flow control device 600, as shown in figure 6A, in a second position. As shown, the tilt element
    620 is compressed between the guide sleeve 616 and the tubular 600. With respect to the position in figure 6A, the rotationally indexed element 608 disPetition 870190035031, from 12/04/2019, p. 23/37
    19/23 saw axialmerrte 617 in a downhole direction, where pin 614 is positioned close to a second end of rail 612 (or well-up axial end). The rotationally indexed element 608 rotates while moving axially between the first position (figure 6A) and the second position (figure 6B). As shown, the magnetic assembly 624 is coupled to the metal elements 618. The magnetic coupling provides a directional force 617 that exceeds the spring force of the tilting element 620 to compress the element. The adjustable flow control device 600 is shown in the process of adjusting the flow path within tubular 602. In one aspect, the second position shown is approximately halfway between the first flow channel position (position one, figure 6A) and a second flow channel position (position three, figure 6C below).
    [0039] Figure 6C, a sectional view of tubular 602 and adjustable flow control device 600 showing the adjustable flow control device of figures 6A and 6B, in a third position. The magnet assembly 624 is disassembled, thereby removing the magnetic field and uncoupling the assembly from the metal elements 618. Consequently, the guide sleeve 616 retracts in the direction 630, when it is pushed by the tilt element force 620. When the element rotationally indexed 608 moves axially 630 in a well-up direction, pin 614 is positioned near the first end of the rail 612 (or axial downhole end). As shown, the rotationally indexed element 608 and the adjustable flow control device 600 are in a second flow channel position, thereby exposing flow hole 607 in a lowered part 610 (not shown). In one aspect, four flow channels or paths are provided in the multi-channel flow element 604, where a selected channel may be in communication
    Petition 870190035031, of 12/12/2019, p. 24/37
    20/23 fluid with one or more fluid orifices 607 in the tubular 602. Consequently, the positions illustrated in figures 6A-6C show the adjustable flow control device 600 deviating from a first flow channel position to a second channel position flow. In one embodiment, the first flow channel position in figure 6A corresponds to the position shown in figure 3A. In addition, the second flow channel position of figure 6C can correspond with the position shown in figure 5A. The illustrated magnetic assembly 624 provides an apparatus for adjusting the flow of fluid within the tubular 6023 locally, using a processor and program, or by a remote user, where the apparatus includes few moving parts. The processor and / or program may be located in a pit or on the surface, depending on application needs and other restrictions.
    [0040] Figure 7 is a sectional view of adjustable flow control device 700 and tubular 702. As shown, the adjustable flow control device 700 is in a first position, whose position can be determined before unfolding the device flow control 700 in the well. The flow control device 700 is shown to include a multi-channel flow element 704 and adjustment device 705. The first position of the adjustment device 705 corresponds to a channel selected from the multi-channel flow element 704. In In one aspect, the multi-channel flow element 704 includes several flow channels in a direct flow region 748, where each channel has a different flow resistance. In a well injection mode, the flow resistance for each channel can be configured to restrict a flow of a selected fluid, such as gas or water, from tubular 702 in the formation. Consequently, the adjustable flow control device 700 is used in an injection well to inject an amount
    Petition 870190035031, of 12/12/2019, p. 25/37
    21/23 of selected fluid within a selected zone of a formation, in which the injected fluid displaces hydrocarbons from the formation. Thus, the injected fluid causes the flow of hydrocarbons from the formation zone to an adjacent well.
    [0041] As shown, the multi-channel flow element 704 is configured to allow fluid flow through a flow port 707 in the tubular 702 to a selected channel that includes a series of stages. In aspects, flow port 707 is located in a grooved portion of tubular 702, thereby allowing fluid flow from all ports 707, if covered or uncovered by a rotationally indexed element 708. In one aspect, four port holes flow are located circumferentially, at 90 degrees with respect to each other. The rotationally indexed element 708 includes a pin 714 (also referred to as a J pin or guide pin) positioned on a rail to control the rotational movement of the rotationally indexed element 708. In aspects, the rail is a standardized opening in the element (as shown in figures 3A, 4A and 5A) which allows rotational and axial movement to adjust the flow of fluid through the flow control device 702. In one embodiment, the axial movement of components located within the tubular 702 can adjust the rotationally indexed element 708 to cause the flow and fluid (injection) of tubular 702 to form through a selected channel of the multi-channel flow element 704.
    [0042] The adjustment device 7045 includes the rotationally indexed element 708, tilt element 720 and guide sleeve 716, each located outside the tubular 702. The guide sleeve 716 is coupled to the rotationally indexed element 708, which allows movement axial tubular 702 and sleeve 716, while allowing rotational movement independent of the components. The 716 guide sleeve is also
    Petition 870190035031, of 12/12/2019, p. 26/37
    22/23 coupled to the tilting element 720, such as a spring, which resists axial movement when compressed. In one aspect, the tilt member 720 is fixedly attached to the tubular 702 at the opposite end of the guide sleeve. In the embodiment shown, the guide sleeve 716 is coupled to a guide pin 722 located in a slot. Pinoguette 722 controls the axial range of motion of the guide sleeve 716 and the tilt element 720. An internal element (also referred to as a coupling element, a coupling device or coupling tool), such as a clamp 724, is located within the tubular 702 and includes protrusions 726 configured to selectively engage a diverter sleeve 728 which is a part of or coupled to the guide sleeve 716. Therefore, the adjustable flow device 700 shown in figure 7 may include similar components of and be functionally similar to the devices shown in figures 3A-5B. In addition, the flow of fluid through device 700 in an injection well application is the reverse of that described in Figure 2, where fluid flows from well-up into the tubular to a first region 212, through a second region 210 and in a formation. In other embodiments, the adjustable flow device 700 uses any suitable mechanism to selectively control the flow of tubular 702 in the formation, such as the magnetic assembly shown in figures 6A-6C. Furthermore, it should be understood that the device used for injection wells can use any device suitable for adjustable flow, including those shown in figures 2-6C. As shown, a fluid flows from a well-up source, such as a surface tank, in the tubular 702, as shown by arrow 750, through orifice 707, shown by arrow 752, to a channel selected from the adjustable flow device 700 and within the formation, shown by arrow 754. Consequently, the adjustable flow control device 700 provides an apparatus for controlling the amount
    Petition 870190035031, of 12/12/2019, p. 27/37
    23/23 and fluid flow rate from the injection well tubular 702 within the formation.
    [0043] It should be understood that figures 1-7 are intended to be merely illustrative of the teachings of the principles and methods described here and whose principles and methods can be applied to design, build and / or use inflow control devices. Furthermore, the preceding description is directed to particular modalities of the present description for the purpose of illustration and explanation. It will be evident, however, for someone skilled in the art that many modifications and changes to the modality described above are possible without departing from the scope of the description.
