    “SYSTEM AND METHOD FOR MEASURING CONDITIONS FOR DRILLING THE OIL WELL, IN PARTICULAR, IN CHECKING A FINAL DIAMETER FOR DRILLING THE WELL”
    Field of the Invention
    The present invention relates to the measurement characteristics and conditions of drilling the oil wells of the well walls in the oil and gas industry. More particularly, the present invention relates to a system for measuring a borehole diameter after drilling and the well widening. The present invention also relates to a system for measuring a borehole diameter simultaneously with borehole drilling and widening. In addition, the present invention deals with a method for checking the diameter of a perforation during and after drilling and widening.
    Background of the Invention
    Drilling is part of a process for extracting a natural resource, such as groundwater, natural gas, and oil, or for exploring the nature of the underground material. A well or well drilling can be created by using a drill rig to rotate a drill string, which has a drill bit attached at its end, in order to drill into the ground to a desired depth. Drill commands and drill pipe sections add length, weight and support along the drill string as well as deepening the well bore, and different types of cutting drills in all types of rock formations and soil combinations. The drilling fluid or drilling mud pumps through the inside of the column, outside the drill bit by nozzles or jets, and above the annular space for the
    2/30 surface, in order to create the appropriate physical and hydrostatic conditions to safely drill the well. In addition, cuttings are removed from the well in the circulation of the drilling mud flowing to the surface.
    After drilling a section of the well, steel linings, which are slightly smaller in diameter than the diameter of the well drilling are placed in the well. Cement can be injected into the annular space between the outside of the linings and the well. The coating system strengthens the integrity of the new well drilling section to allow for deep drilling and other benefits. A series of smaller drills and smaller drill bits with the respective smaller steel coating systems are used for drilling, such that a finished well includes wells within wells In the state of the art technology, the diameter of the well drilling is reduced as each section of the coating systems is put in place.
    However, the latest developments in well drilling require deeper and deeper wells, even super-deep wells from wells 8 to 9.6 kilometers below the surface. Continued reliance on fossil fuels, in particular oil and gas, has pushed the drilling and exploration industry to explore ultra-deep waters (water depths over 2,000 meters) with super-deep wells drilled at depths over more 7,500 meters. The conditions of temperature, distance and pressure of super-deep wells require a large amount of resources to extract oil and gas. The recent extreme depths cannot be reached with the state of the art technology, because the decrease in the diameter size of the
    3/30 drilling the well sets a limit on the drilling depth.
    The industry's response to forming super-deep wells has been countersinking or widening by movable arms, which widens the diameter of the well by removing the layer of material already stressed and overturned caused by the drill. Countersinking has been known in metallurgy and machining to affect the mechanical properties of a good surface finish. Applied in the field of well wall drilling, a movable arm reamer is a cutting tool activated in the drill column to enlarge the well. The typical movable arm reamer has a composition of extending and retractable parallel helical or straight cutting edges along the length of a cylindrical body and is placed higher than the drill bit along the drill string. The cutting edges are angled and with a slight undercut below the cutting edges to make initial contact with the sides of the well bore.
    The adaptation of movable arm reamers has led to even greater challenges in the oil and gas sector. Controlling the drill bit and the drill column when drilling the well has always required special attention. The measurement systems during drilling (MWD) and profiling during drilling (LWD) collect data in real time, which is the data displayed during drilling, and the data stored in memory, which is the data displayed after drilling. The data helps to ensure the correct direction and conditions of drilling and record forming properties. The MWD system measures and takes record readings, such as natural gamma rays, well drilling pressure, temperature, resistivity, formation density, etc., and data can be transmitted as quickly as possible in real time using
    4/30 of mud pulse telemetry, wired drill pipes or other means. The stabilizers added to the drill string are mechanical solutions to reduce the drill string vibrations, improve the accuracy of the drilling direction of the well and improve drilling efficiency. In the recent extreme distances and depths achieved with reamers, it becomes even more important for accurate monitoring because of the costs and resources invested, and has become even more challenging with the mobile arm reamer positioned on the drill string. The movable arm reamer is a separate cutting tool, so that the drilling diameter of the drill bit and the largest final diameter after the reamer are different. The state of the art does not provide for final confirmation of the diameter of the well's drilling, after the reamer and during drilling.
    For the measurement of the diameter of the well drilling, the typical current system is a mechanical caliper tool with a steel handle, which collects a caliper profile of the guided measurements of the size and shape of a well drilling, after drilling of the well section has been completed and after the drill string and drill bit has been removed from the well. The diameter of the well bore is an extremely vital piece of information for super-deep wells, as the well bore must be of a particular size in order to fit the appropriate coating system. The necessary extreme depths cannot be reached if the wells become too small for the linings. The stacking length of the liners cannot be supported or selected correctly if the dimensions of the well drilling are too small. The mechanical caliper tool with steel cable confirms the diameter of the
    5/30 drilling the well, once it is opened and removed from the bottom of the well, two or more articulated arms push against the walls of the well, making measurements of the diameter of the well. This mechanical caliper tool with steel cable of the state of the art requires a complete stoppage of the drilling operation and removal of all drilling equipment from the well. As such, the mechanical caliper tool (calibrator) with steel cable and the method of using the caliper tool (calibrator) are very significant, with respect to the probe time and efficiency for the well.
    In the past, several patents have been granted in the area of measuring the diameter of the well drilling. For example, US patent 7,168,507, issued to DOWNTON on January 30, 2007, and published as US 20030209365, discloses an invention for recalibrating downhole sensors. A first composition of low-cost and small sensors is located in the drill column adjacent to the drill, and a second, more accurate sensor composition is located in a more protected upper position in the drill column away from the drill bit. As drilling progresses, the second composition collects data to calibrate a departure from the first sensor composition. The invention discloses the placement of sensors away from the drill bits for better accuracy for measuring the gas flow within the well drilling.

The non-rotating stabilizer is adapted

    At the moment, there is no LWD equipment (profiling during drilling) available, dedicated to measurement during drilling and widening, that is, MWD systems (measurement during drilling), to determine the final diameter of the well wall. any section of the well that has been drilled. Many companies claim to be able to provide real-time diameter measurements of the well wall, but in reality, such data is apparently an alleged reading, or a pseudo reading of the caliper, in such a way that accuracy is questionable. The problem seems to be related to a number of factors: the change in the composition of the drilling mud affects the reading, the drilling of the well is irregular and the position of the composition of the bottom of the well and the sensors are not generally equidistant to the wall of the well. well, such that the reading depends on the position of the sensor.
    It is an object of the present invention to provide a system and method for measuring the characteristics and conditions of a well bore.

    Brief Description of the Invention
    The present invention is a system and method for measuring the conditions of a well bore, in particular, for the verification of a final diameter of a section of a well bore. The system of the present invention comprises a drill string, an enlarging means and a tool body with a sensor. The drill string has a downhole composition with a drill bit at one end of it and a circulation medium for the drill mud. The widening means or movable arm widener are connected to the drill string above the drill bit and have a passage for the drilling mud flow. There are cutting edges in the widening medium, in order to increase the diameter of the well drilling after being drilled by the drill bit of the bottom composition. The tool body also connects to the drill string and the sensor detects downhole conditions, such as the hole diameter of the well. The tool body is mounted on the widening means and has a smaller diameter than the widening means. The tool body is rotationally and axially aligned with the drill string, so that the drilling mud flow is within the drill string, through
    11/30 from the inside of the tool body, and then on the outside of an outer shell-shaped body to the tool body and above the surface. The tool body can also have a plurality of stabilizing blades for stabilizing the drill string.
    The sensor means can be constituted by an ultrasound transducer, with the adjustable signal amplitude, in order to measure the diameter of the well drilling. The sensor means has at least one fixed position, the fixed position being located on the outer shell-shaped body or on the stabilizing blades. The tool body has regular components for communicating and storing sensor data and communicates or connects to the sensor means. In addition, there is a means to communicate information from the bottom of the well to a location on the surface. Any known transmission method, such as rock bottom to surface sub telemetry, mud pulse or wireless link to the third part of the wired pulse or tube can be used.
    The system of the present invention can also include a means for calibrating the sensor in the tool body. When the circulation medium for the drilling mud reaches the surface location, there is a duct for resuming the mud flow. The calibration means interact with this sludge return flow line or the sludge through the drill column. The calibration means for the sensor consist of transducers inside the tool body, in fluid connection with the drilling mud circulation system through the drilling column and / or in a surface location in fluid connection with the drilling system. drilling mud circulation. A first ultrasound transducer inside can be in the passage of the mud flow inside or outside the tool body and a
    12/30 second ultrasound transducer on the surface can be in the mud flow line at the surface location. A processor for comparing data from the first and second transducers allows more accurate data sensor readings to be adjusted and therefore improved drilling efficiency. In particular, the first ultrasound transducer is positioned in the flow passage with a spaced position of fixed distance with a known diameter, transmitting a reading through the known diameter during drilling, in order to record the ultrasonic travel time through the known diameter . If the travel time for a known distance through the mud flow changes, then the reading sensor for the well drilling wall must be calibrated accordingly. The second ultrasound transducer can be a surface calibration block with known dimensions in the mud return flow line, transmitting a reading signal through the calibration block, in comparison to the properties of the drilling mud at the surface location and in the tool body. Similar to the first ultrasound transducer, the calibration block has an input with a fixed distance. The travel time for this fixed distance is monitored through the return flow of the mud. If the travel time for the fixed distance through the mud flow changes, then the reading sensor for the well drilling wall should be similarly calibrated according to that change. The second ultrasound transducer can be a backup copy of the calibration means and require adjustment of the time for readings and the time of the mud flow at the bottom of the well and the return flow of the mud at the surface. The transducers for the sensor can be similar to the transducers for the calibrator.
    13/30
    The system of the present invention can also include an auxiliary tool body connected to the drill string. The auxiliary tool body has an auxiliary sensor means for the detection of downhole conditions, which functions analogous to the sensor means in the tool body. The auxiliary tool body is mounted between the widening medium and the bottom composition with the drill bit, such that the auxiliary sensor readings are from a different bottom location of the body sensor means tool. The auxiliary sensor can also be correspondingly adjusted by means of calibration in a similar way.
    The method for verifying a well bore, in particular for measuring a final diameter of a well bore, corresponds to using the system of the present invention. Firstly, a pilot well borehole is drilled using a borehole column having a borehole composition with a borehole drill at a terminal end thereof and a circulation system for the borehole. Then, a drilling of the enlarged well is drilled using a reamer attached to the same drill string above the drill bit. The reamer has cutting edges in order to increase the diameter of the pilot well drilling for the drilling of the enlarged well. Finally, the diameter of the enlarged well bore is measured by the sensor in the tool body of the present invention, above the reamer. The method includes using the sensor on the tool body or on the stabilizing blades on the tool body.
    The real-time communication of information from a bottom location to a surface location is another step in the method of the present invention. The stage uses the
    14/30 well-known technology, such as a rock bottom with surface sub telemetry, mud pulse or wireless link to the third part of the wired pulse or tube. Another possible step in the method of the present invention is to calibrate the sensor, which will measure the drilling of the enlarged well. The calibration step involves adjusting for monitored drilling mud flow properties at the bottom of the well and / or at a surface location. Yet another step in the method of the present invention is the coupling of an auxiliary tool body with an auxiliary sensor to the drill string. The auxiliary tool body and auxiliary sensor detect downhole conditions, such as the diameter of the well, between the reamer and the bottom composition with the drill bit. The auxiliary and calibration sensors allow real-time monitoring with greater accuracy and precision.

    Detailed Description of the Figures
    Figure 1 shows a deep water drilling rig (1), marine riser (duct) (2) and well section (3) for a typical underwater well. These structures are used in super deep drilling. The system (10) for measuring well drilling conditions, such as checking the diameter of the well drilling, of the present invention is shown in the well section (3). Figures 2A and 2B are exploded schematic views of the system (10) for measuring the final diameter of a well bore. The system (10) includes a drill string (12), an enlarging means (14) and a tool body (16). The drill string (12) has a downhole composition (18) with a drill bit (20) at one end of it. The drilling column (12) also includes a circulation means (22) for the drilling mud (24). The widening means (14) connects to the drilling column (12), above the drilling bit (20), so that the parts of the pilot well (26) are differentiated from the drilling of the enlarged well ( 28). The widening means (14) is compatible with the circulation means (22) and maintains a passage (30) for the flow of the drilling mud (24) through the widening means
    16/30 (14). It is important to note that the widening means (14) has activable cutting edges (32), in order to increase the diameter of the pilot well (26) after being drilled by the drill bit (20) of the bottom composition well (18).
    The tool body (16) has a fixing means (34) for the drill string (12), as shown in figure 3, the exploded schematic view of the system (10) of the present invention. This fixation means (34) can be screwed or secured with pins or any other device acceptable for any type of drilling command (29). Figure 3 shows the tool body (16) mounted above the spreading means (14). The diameter of the tool body (16) is smaller than the widening means (14) and the drill bit (20). In this way, the tool body (16) can be a traditional stabilizer for a drill string (12), since it is rotationally and axially aligned with the drill string (12). Alternatively, the tool body (16) can securely attach a drill driver (29) to the drill string (12) as a fixing means (34) to an existing part of the drill string (12). In addition, the tool body (16) can have a plurality of stabilizing blades (38), where a maximum diameter of the stabilizing blades (38) on the tool body (16) is even less than a diameter of the widening means (14) and the drill bit (20). These stabilizing blades (38) are non-cutting protuberances aligned with the drilling column (12), which adds stability to the drilling column (12) and to the bottom composition (18) by reducing vibrations and providing rigidity.
    Figures 6 and 7 show the tool body (16) with sensor means (36) for detecting pit bottom conditions. The tool body (16) can be made of steel, forming a body in
    17/30 outer shell shape (40) and an inner shell (42), where ο inner shell (42) is an inner sleeve lining locked inside the body in the outer shell form (40). The drilling mud (24) can flow into the drilling column (12), through a passage (50) through an interior (51) of the tool body (16) and then along the side shell-shaped outer body (40) of the tool body (16).
    Also in figures 6 and 7, the tool body (16) with sensor means (36) of the system (10) for measuring the well drilling conditions, including the verification of the well drilling, also comprises the contents necessary to collect , store and transmit data. Consequently, the tool body (16) has a programming application interface (27) housed within the inner housing (42). The sensor means (36) can be constituted by an ultrasound transducer (48) with the adjustable signal amplitude, in order to measure the diameter of the drilling of the enlarged well (28). The ultrasound transducer (48) can be made of a piezoelectric material. The sensor means (36) has at least one fixed position, the fixed position being located on the shell-shaped external body (40) or on the stabilizing blades (38). Figure 7 shows the fixed position locations in each sensor medium (36) at the bottom of the well and Figure 4 shows the location of the surface (53). The sensor means (36) at the bottom of the well in Figure 7 connects to the inner shell (42) within the outer shell-shaped body (40) by means of communication signals or hardware connections to transmit sensor data to the system (10). Figure 7 shows the sensor means (36) with a separate unit on a stabilizer blade (38). Any number of individual sensors can be placed on the tool body (16) as the sensor means (36) of the present invention. THE
    18/30 figure 6 shows an end of the tool body (16) with a plurality of sensors (36) with a concentric arrangement (48). The sensor means (36) can be on the shell-shaped outer body (40) or on the stabilizing blade (38). The inner shell (42) connects to the sensor means (36), such that the inner shell (42) contains a power source (25), the circuit (55) and the memory storage components (57) in a pressurized environment. A power source (25), such as a battery, fits inside the inner shell (42), the inner shell (42) being within the shell-shaped outer body (40) of the tool body (16). Figure 6 shows the inner shell (42), with an O-ring seal fitted by friction to the shell-shaped outer body (40), and the inner shell (42) and the shell-shaped outer body (40) are longitudinally aligned, such that the drilling and rotation mud flow (24) through the drilling column (12) are not overloaded.
    Additionally, a means for communicating information (59) from a bottom location to a surface location can be mounted on the inner housing (42) of the tool body (16). The means of communication (59) can be any well bottom known for surface sub telemetry, mud pulse or wireless link to the third part of the wired pulse or tube. Communication allows real-time data to be presented for monitoring. In this way, it will be possible to determine the enlargement efficiency without interrupting the drilling operations and without removing the drilling column (12) for a mechanical cable caliper measurement of the state of the art. The data can be presented as shown in figure 5, where the horizontal axis shows the diameter and the vertical axis shows the depth. The diameter of the planned drill bit (60) and the diameter of the
    19/30 planned reamer (62) are supposed to be defined, but are subject to wear and tear, in such conditions and the reamers are subject to malfunction, so that they cannot fully extend when activated. Figure 5 shows how the system (10) and method of the present invention control the diameter of the enlarged perforation (64) while the enlargement means (14) is worn or retracted. The system (10) also controls the diameter of the drilled pilot well (66). The minimum well size (68) required for successful operation, that is, fitting a casing into the well and cementing it in place is also shown. As an example, if the well drilling must measure a minimum of 13.5 inches to properly allow the casing to be placed correctly, then the present system (10) provides this accurate and safe measurement. The state of the art cannot provide the same accuracy during drilling and depends more on an algorithmic solution for the diameter of the pilot well and the diameter of the drilling of the examined extended well. The system (10) eliminates the risk of drilling wells that are too narrow to allow continuous drilling and other operations that require a certain size of well drilling, which are essential for reaching super-deep resources and establishing super-deep production of Oil and Gas.
    Another feature of the system (10) of the present invention is shown in figures 1, 3, 4 and 7. Because the drilling column (12) includes a circulation medium (22) for the drilling mud (24), there is a line of mud flow (44) at the location of the drilling rig surface (1) and the bottom of the well in figure 1. The system (10) interacts with this mud flow line (44) with a medium (46) for the calibration of the sensor means (36). The calibration means (46) is composed of ultrasound transducers (49) similar to the
    20/30 sensor (36). These ultrasound transducers (49) are placed in different locations from the transducers to the sensor means (36). Figure 7 shows a first ultrasound transducer (49) inside (51) the tool body (16) in fluid connection with the circulation system (22) of the drilling mud (24) through the drilling column (12) . Figure 4 shows a second ultrasound transducer (52) at the location of a fluid connection surface (53) with the drilling mud circulation system (22) (24). The transducers of the sensor means (36) and the calibration means (46) can be similar, but they are placed in different structural locations in relation to each other and the other parts of the present invention (10).
    Figure 7 shows a first ultrasound transducer (49) of the calibrator (46) in the passage (50) for the flow of the drilling mud (24) through the tool body (16). Figure 4 shows a schematic view of a second ultrasound transducer (52) of the calibrator (46) in the mud flow line (44) at the surface location (53). For example, figure 4 also shows the processor (61) in communication with both transducers (49). The data from the first and second transducers (49) and (52) can be processed in order to allow adjustment of the data coming from the sensor (36) of the tool body (16). Calibration is important for greater precision and accuracy of the sensor medium (36) of the present invention. The drilling mud (24) can affect the accuracy of the readings from the sensor medium (36) because the various particles and density variations occur during active drilling, thus MWD systems have a considerable risk of error. The system (10) of the present invention reduces this error with the calibration means (46) for the sensor means (36) of the tool body (16).

    In particular, the first ultrasound transducer (49) is placed in the passage (50) for the flow with a spaced position of fixed distance (63) with a known diameter, transmitting a reading through the known diameter during drilling, in order to record the travel time along the known diameter. The travel time readings along the known diameter and through the drilling mud (24) can be monitored continuously. If the reading for this known diameter through the mud flow changes, then the sensor (36) reading the well drilling wall must be calibrated according to this change. For example, travel time is 60 pseconds for traveling across and back from a distance of 2.0 inches in continuous monitoring mode. If the travel time increases to 65 psec to travel the same distance, then there is no interference from the drilling mud (24). The sensor means (36) must be calibrated so that the travel time for the distance of unknown diameter from the sensor to the well drilling wall is interpreted correctly. If the travel time for the unknown distance is 60 psec, then the unknown distance is less than 2.0 inches because of the calibration adjustment from the first ultrasound transducer (49).
    The second ultrasound transducer (49) can be a surface calibration block (52), as shown in figure 4, with the known dimensions of the mud flow line (44), transmitting a reading through a calibration block. Unlike the transducers (48) of the sensor means (36), but still similar to the first ultrasound transducer (49), the calibration block (52) has an input (65) with a fixed distance. The travel time for this fixed distance is monitored through the mud flow. If the readings from the
    22/30 travel time for the fixed distance through the mud flow changes, then the sensor reading (36) for the well drilling wall must be similarly calibrated according to this change. The second ultrasound transducer (49) as the calibration block (52) is a means of calibrating a backup and requires adjusting the time for readings and the time of the mud flow (30) at the bottom of the well and the flow of mud (44) on the surface. Thus, the system (10) of the present invention can at least provide drilling mud adjustments (24) based on the location of the surface, as a backup for adjustments based on both the surface location and the bottom location, for the sensor means (36) at the bottom of the well.
    Another embodiment of the system (10) of the present invention includes an auxiliary tool body (116) with a fixing means (34) for the drill string (12) and an auxiliary sensor means (136) for the detection of downhole conditions, such as the diameter of the well bore. As shown in figure 3, the auxiliary tool body (116) is mounted between the widening means (14) and the pit-bottom composition (18) with the drill bit (20) and the auxiliary tool body (116) similarly it has a smaller diameter than the widening means (14) and the drill bit (20). The auxiliary tool body (116) can have characteristics similar to those of the tool body (16), such that the auxiliary tool body (116) is virtually identical, except for placement in the drill string (12). Thus, figure 3 shows an auxiliary tool body (116) having an auxiliary sensor means (136) for the detection of downhole conditions, a plurality of auxiliary stabilizing blades (138) and an auxiliary means (159) for communicating information from a
    23/30 bottom location for surface location. The maximum diameter of the stabilizing blades (138) on the auxiliary tool body (116) is even smaller than a diameter of the widening means (14) and the drill bit (20), and the stabilizing blades (138) are protrusions. non-cutting edges aligned with the drill string (12). The auxiliary tool body (116) is another stabilizer positioned below the reamer (14) on the side with the state of the art LWD tools. Figure 2B shows the positioning of the auxiliary tool body (116).
    The auxiliary tool body (116) also includes a corresponding auxiliary sensor means (136), which may consist of an ultrasound transducer (148), with the amplitude of the signal adjustable, in order to measure the diameter of the perforation of the well. The auxiliary sensor means (136) may consist of piezoelectric materials. The auxiliary sensor means (136) can also be fixed in position on the shell-shaped external body (140) of the auxiliary tool body (116) or on the stabilizing blades (138). The means of communication of the corresponding bottom surface, the inner casing, the power source, etc., are also housed in the auxiliary tool body (116). Auxiliary tool body readings (116) provide pilot well drilling readings similar to the state of the art. In combination with the characteristics of the present invention, the system (10) provides even greater precision and early warning of reamer irregularities (14). For example, the operation of the reamer (14) can anticipate a slower or faster rate of drilling based on readings from the auxiliary tool body (116), which detects diameter deviations, possibly due to rock formation or variations of the mud. The auxiliary tool body (116)
    24/30 can also contribute to the readings of the calibration means (46) in monitoring the variations of the drilling mud (24).
    The method for checking a well bore, in particular for measuring a final diameter of a well bore, includes the step of drilling a pilot portion of the well bore (26) using a drill string (12) which has a bottom composition (18) with a drill bit (20) at a terminal end thereof and a circulation system (22) for the drilling mud (24). The circulation system (22) flows drilling mud (24) through the drilling column (12) and back to a surface location. Then, the method includes drilling an enlarged well (28) using a reamer (14) connected to the drill string (12), above the drill bit (20). The reamer (14) has a passage for the flow of the drilling mud (24) and cutting edges (32), in order to widen the diameter of the pilot well drilling for the enlarged well drilling. The method also includes measuring a diameter of the drilling of the enlarged well by a sensor (36) on a tool body (16) connected to the drilling column (12) and mounted on the reamer (14). The communication of information in real time from a bottom location to the surface location is another step in the method of the present invention. The bottom of the well known to the surface sub telemetry, mud pulse or wireless link to third party pulse or wired tubes transmit the sensor readings for use during drilling. The method of the present invention provides a more accurate final drilling check of the well, because the measurement is taken after all well drilling cuts have been completed, unlike the state of the art LWD tools.
    25/30
    The method for checking a well bore can also specifically incorporate measurement from an ultrasound transducer, sometimes piezoelectric, with the signal amplitude adjustable as the sensor (36), where the sensor (36) is fixed in its position. This fixed position can be located on the shell-shaped external body (40) or on said stabilizing blades (38). The sensors at any of these locations can provide the data for the present invention. More than one location can have a sensor, so more data is used to make the most accurate measurements. Each location has particular advantages. For example, the location of sensors on the stabilizer blades (38) increases the accuracy of the reading because of the proximity to the well drilling wall and reduced drilling mud interference with the ultrasound signal that passes through the drilling mud. The transducers (48) of the sensor means (36) must be able to interact with the well drilling wall, when placing the tool body (16), in order to take a measure for verification.
    Another step in the method of the present invention is to calibrate the sensor (36) of the tool body (16) by means of calibration (46) composed of transducers (49), in an interior (51) of the tool body (16 ) in fluid connection to the circulation system (22) of the drilling mud (24) through the drilling column (12) and / or at a surface location (53) in fluid connection with the circulation system (22) of the mud hole (24) in the mud flow line (44) on the surface. Thus, the calibration means (46) can include a first ultrasound transducer (49) in the passage (50) for the flow of the tool body (16) and a second ultrasound transducer (49), which can be a block of calibration (52), in the mud flow line (44) at the surface location. The passage (50) forms a flow path for the mud
    26/30 drilling (24) through the tool body (16). The data processed from the first and second transducers (49) and (52) allows adjustment of the data from the sensor (36) during drilling. The calibration corrects deviations caused by changes in the drilling mud properties (24), so that the final verification of the drilling diameter of the well is more precise and exact. Specifically, the first ultrasound transducer (49) is positioned at the passage to the flow with a known diameter, transmitting a continuous reading through the known diameter, during drilling, in order to record the travel time along the known diameter. Likewise, the second ultrasound transducer (49) is a surface calibration block (52) with known dimensions placed on the mud flow line (44), transmitting a continuous reading through the calibration block. Any change in continuous readings on one or both of the transducers (49) means that the ultrasound readings are being affected by changes in the drilling mud (24), such that the sensor (36) requires an adjustment for a more accurate reading . Or, transducer 49 can be used to adjust the readings of the transducers (48) of the sensor means (36), so that the calibration block (52) can be a backup copy of the bottom calibration means (46) from the well, that is, the first transducer (49) in the passage (50), if there is an interruption in the well bottom communication medium.
    Yet another step in the method for verifying a well bore includes the connection of an auxiliary tool body (116) with an auxiliary sensor (136) to the drilling column (12). The auxiliary sensor (136) detects downhole conditions, such as the diameter of the well bore, as an LWD tool in the downhole composition (18). The auxiliary tool body (116)
    27/30 is mounted between the reamer (14) and the bottom composition (18) with the drill bit (20), in such a way that the auxiliary sensor (136) works analogously to other state-of-the-art LWD tools , measuring the conditions for drilling the pilot well. Similar to the tool body (16), the measurement with the auxiliary tool body (116) includes the auxiliary tool body (116) having a smaller diameter than the reamer (14) and drill bit (20) and a plurality stabilizer blades (138). The auxiliary sensor (136) makes the same adjustments for the fixed location, such as the stabilizer blades (138), which communicates with the location of the surface, and is calibrated as the tool body (16). The auxiliary sensor means (136) can also contribute data from the drilling mud (24) to the calibration medium (46). The additional sensor data provides greater precision and accuracy for real-time data analysis, because pilot well drilling data is based on real-time data, rather than the actual drill bit diameter. While drilling is taking place, real-time signal information about the diameter of the well can be transmitted from the bottom of the well to the surface, using traditional methods, that is, sub telemetry (or mud pulse or connection link) wireless for third-party pulse) or through a wired tube (inteli-tube), in order to provide real-time information on the well diameter during drilling, called DBD (well drilling data). The method of the present invention constantly assesses the impact of wear on drilling tools to avoid calculation errors that can cause inefficiency during the drilling process.
    The system and method for verifying a well bore of the present invention improves the determination of the final diameter of a well bore, which is a well bore after
    28/30 drilling and after enlargement in real time. The present invention has an actual measurement, which is more accurate than the measurements, which currently can use algorithmic calculations. The present invention has real-time capability, in addition to the stored memory, so that adjustments to the drilling program can be made before excessive expenses occur. In addition, the drilling operation does not have to stop in order to run a mechanical steel wire caliper by drilling the well to a log of the well diameter. In addition, the system of the present invention is compatible with existing technology and can be applied to any well expansion operation. It is conceivable that the enlargement technology can advance with the cutting edges and adjustable diameters and the present invention can be integrated into any version of a reamer and downhole composition.
    The system and method for verifying well drilling with calibration means is another important innovation. A surface and well bottom calibration block allows changes in the drilling fluid, which is flowing down through the drill column and into the annular space, to be monitored and the travel time (echo or attenuation signal) when over an unknown distance (pit wall sensor) can be corrected automatically to allow any change in drilling fluid (mud) properties using the downhole calibration sensor and / or the surface calibration block sensor to make corrections to the attenuation changes or the stand-off flight time (distance between the sensor and the well drilling wall), due to changes in the drilling mud. The positioning of the tool body is also a stabilizer for the drill string itself. As a stabilizer, no real drilling and
    29/30 enlargements are carried out, which reduces the risk of damage and interruption to the invention.
    Another unique feature of this application is that, in comparison, the sensor and the auxiliary sensor in the bottom composition provide data from the top and bottom of the widening, thus allowing a comparison between the lower and upper signal readings. The increase in travel time (echo signal), through the mud column in the annular space, with the ultrasound sensor, would indicate that the enlarged well is larger than the pilot well, which was drilled with the smallest drill bit diameter. drilling and will have a faster travel time (echo signal) indicating a shorter distance between the sensor and the well drilling wall.
    Another advantage of the real-time data of the present invention is that the system is dedicated to focus on the final drilling diameter of the well, and will be calibrated for the correct drilling mud properties. Thus, a more accurate reading of the annular space between the sensors and the final (enlarged) wall of the well drilling will be achieved. The sensors will operate and emit a continuous signal, thus recording information about the diameter of the well continuously, that is, while the BHA (bottom composition) is rotating and moving (that is, during drilling) or move up or down (ie while out of the bottom or maneuvering) or stationary (ie, circling).
    The system provides more accuracy and precision before and after enlargement, which monitors how well the enlargement functions. To activate this higher precision, the auxiliary tool body with auxiliary sensor can be executed below the reamer, in the pilot well, which allows a comparison between the ultrasound signal of the pilot well below the reamer and the ultrasound signal of the enlarged well
    30/30 in the well with the largest countersunk diameter. These readings of the ultrasound signal will be guided according to the time and the depth drilled, for comparison and the data that will give indications if the reamer is cutting a size of the correct caliber or if the reamer with movable arm or reamer failed to activate, so that the pilot well and the ultrasound signals from the extended well would be the same, showing that the diameters of the well drilling are the same. The data can also show whether the enlargement medium has temporarily opened and then closed unexpectedly. As illustrated in figure 5, the ultrasound signals from the pilot well (66) and the ultrasound signals from the countersunk well (64) initially began to read different drilling diameters from the well and gradually or suddenly converge, indicating that the well was not being extended properly. If the ultrasound readings from the enlarged well gradually start to converge with the readings from the pilot well, then this would indicate that the reamer would be wearing out and the well would be becoming conical.
    Accordingly, the system and method of the present invention provides an effective and cost-effective alternative to the state of the art technology.
    The foregoing description and description of the invention are illustrative and explanatory. Various changes to the construction details illustrated can be made without departing from the true scope of the invention.
