Description

Technical Field

[0001] This invention relates to the field of oil and gas drilling technology, and in particular to a drill pipe identification structure, identification method, and drill pipe management system. Background Technology

[0002] With the continuous advancement of oil and gas drilling technology, the number of deep wells, exploratory wells, and challenging wells is increasing, placing more stringent demands on the performance of drilling tools. This trend has led to an increase in the types and quantities of drill pipes, making drill pipe management more complex.

[0003] Existing drill pipe management mainly falls into two categories: fixed-team management and graded management. Fixed-team management disregards specific well depths, well types, or other specific conditions, consistently using the same set of drill pipe equipment and treating all drill pipes as being of the same quality level, without distinguishing their condition. This method neither optimizes drill pipe resource utilization nor promptly identifies damaged drill pipes, impacting drilling efficiency and safety. Graded management involves periodically inspecting and classifying drill pipe usage, grouping drill pipes of the same grade together. When using drill pipes, different grades are used based on different regions, well depths, and well types. This method can improve drill pipe utilization to some extent, but currently, it is difficult to accurately track and analyze the usage of individual drill pipes. Therefore, how to accurately track and identify drill pipes and monitor their usage is a pressing issue in drill pipe management. Summary of the Invention

[0004] This invention provides a drill pipe identification structure, identification method, and drill pipe management system, which can accurately track and identify drill pipes, monitor their usage, and provide a foundation for information-based management of drill pipes at drilling sites.

[0005] In a first aspect, embodiments of the present invention provide a drill pipe identification structure, comprising:

[0006] A drill pipe, configured to move within an oil and gas well, with a label on its sidewall;

[0007] A position detection device, installed on the inner wall of the oil and gas well, detects the position of the tag and generates a corresponding position detection electrical signal; and

[0008] An identification device is rotatably mounted at the wellhead of the oil and gas well. The identification device receives the position detection electrical signal and rotates to face the tag according to the position detection electrical signal in order to read the information of the tag.

[0009] In one embodiment, the position detection device includes:

[0010] A ring-shaped visual sensor, disposed on the inner wall of the oil and gas well, is used to detect the position of the tag and generate a corresponding position detection electrical signal; and

[0011] A first communication module is disposed on the inner wall of the oil and gas well and electrically connected to the annular vision sensor. The first communication module is used to send the position detection electrical signal to the identification device.

[0012] In one embodiment, the identification device includes:

[0013] A turntable is rotatably mounted at the wellhead of the oil and gas well, and the turntable is provided with a through hole for the drill pipe to pass through;

[0014] A drive assembly is disposed at the wellhead of the oil and gas well, and the drive assembly drives the turntable to rotate;

[0015] A reader, disposed within the turntable, is used to read information from the tag; and

[0016] The second communication module is disposed inside the turntable and electrically connected to the drive component. The second communication module is used to receive the position detection electrical signal and transmit it to the drive component.

[0017] In one embodiment, the first communication module is a Bluetooth transmitting device, and the second communication module is a Bluetooth receiving device.

[0018] In one implementation, the tag is an RFID tag and the reader is an RFID reader.

[0019] In one embodiment, the position detection device further includes a first power supply module disposed on the inner wall of the oil and gas well, the first power supply module being electrically connected to the ring vision sensor and the first communication module respectively.

[0020] In one embodiment, the identification device further includes a second power supply module disposed within the turntable, the second power supply module being electrically connected to the drive component, the reader, and the second communication module, respectively.

[0021] Secondly, embodiments of the present invention provide an identification method applied to the drill pipe identification structure as described above.

[0022] In one implementation, it includes:

[0023] The location of the tag is detected by the location detection device, and the location detection electrical signal is generated.

[0024] Based on the position detection electrical signal, the identification device rotates to the position where the tag is located;

[0025] The identification device reads the information from the tag.

[0026] Thirdly, embodiments of the present invention provide a drill pipe management system, including the drill pipe identification structure as described above.

[0027] Compared with existing technologies, the advantages of this invention are as follows: by setting tags on the drill pipe to record drill pipe information, a position detection device detects the position of the tags when the drill pipe exits the well and generates a position detection electrical signal. The identification device rotates to face the tag according to the position detection electrical signal, thereby successfully reading the tag information. Compared with existing technologies that rely on manual tag location, this invention is time-saving, labor-saving, and highly efficient, avoiding the situation where tags are missed due to the uncertainty of the tag's position during the drill pipe's exit from the well, resulting in missed tag readings. At the same time, since the drill pipe carries a large amount of mud and sand when exiting the well, the automatic reading method of the identification device in this invention also ensures the safety of operators, avoiding safety accidents caused by close contact with the drill pipe being exited from the well. In addition, through the coordinated cooperation of the tags, position detection device, and identification device, the accuracy and efficiency of drill pipe wellhead identification are improved, effectively filling the gap in drill pipe information management at the drilling site, providing a foundation for the full life cycle management of drill pipes, and the fully automated identification process also saves human resources.

[0037] The invention will now be further described with reference to the accompanying drawings.

[0038] With the continuous advancement of oil and gas drilling technology, the number of deep wells, exploratory wells, and challenging wells is increasing, placing more stringent demands on the performance of drilling tools. This trend has led to an increase in the types and quantities of drill pipes, making drill pipe management more complex.

[0039] Existing drill pipe management mainly falls into two categories: fixed-team management and graded management. Fixed-team management disregards specific well depths, well types, or other specific conditions, consistently using the same set of drill pipe equipment and treating all drill pipes as being of the same quality level, without distinguishing their condition. This method neither optimizes drill pipe resource utilization nor promptly identifies damaged drill pipes, impacting drilling efficiency and safety. Graded management involves periodically inspecting and classifying drill pipe usage, grouping drill pipes of the same grade together. When using drill pipes, different grades are used based on different regions, well depths, and well types. This method can improve drill pipe utilization to some extent, but currently, it is difficult to accurately track and analyze the usage of individual drill pipes. Therefore, how to accurately track and identify drill pipes and monitor their usage is a pressing issue in drill pipe management.

[0040] Example 1

[0041] like Figure 1 As shown, in order to solve the above-mentioned technical problems, this embodiment of the invention provides a drill pipe identification structure, including a drill pipe 10, a position detection device 20, and an identification device 30; the drill pipe 10 is configured to move within an oil and gas well 50, and a tag 40 is provided on the side wall of the drill pipe 10; the position detection device 20 is disposed on the inner wall of the oil and gas well 50, and the position detection device 20 detects the position of the tag 40 and generates a corresponding position detection electrical signal; the identification device 30 is rotatably disposed at the wellhead of the oil and gas well 50, and the identification device 30 receives the position detection electrical signal and rotates to face the tag 40 according to the position detection electrical signal to read the information of the tag 40.

[0042] As can be seen from the above, by setting a tag 40 on the drill pipe 10 to record the information of the drill pipe 10, the position detection device 20 detects the position of the tag 40 when the drill pipe 10 exits the well and generates a position detection electrical signal. The identification device 30 rotates to be directly opposite the tag 40 according to the position detection electrical signal, thereby successfully reading the information of the tag 40. Compared with the prior art, which relies on manual searching for the position of the tag 40, the present invention is time-saving, labor-saving and efficient, avoiding the situation where the tag 40 is missed due to the uncertainty of the position of the tag 40 during the process of the drill pipe 10 exiting the well, resulting in the tag 40 being missed. At the same time, since the drill pipe 10 carries a large amount of mud and sand when exiting the well, the automatic reading method of the identification device 30 in the present invention also ensures the safety of the operator's life and avoids safety accidents caused by close contact with the drill pipe 10 that is exiting the well. In addition, the coordinated operation of the tag 40, the position detection device 20 and the identification device 30 improves the accuracy and efficiency of wellhead identification of drill pipe 10, effectively fills the gap in information management of drill pipe 10 at the drilling site, provides a foundation for the full life cycle management of drill pipe 10, and the fully automated identification process also saves human resources.

[0043] It should be noted that the identification device 30 makes a circular motion around the wellhead of the oil and gas well 50, thereby changing the angle between it and the tag 40, and rotating it to be directly opposite the tag 40.

[0044] It should also be noted that the power to rotate the drill rod 10 is provided by the drilling rig. The drilling rig's function is to provide the power for the drill rod 10 to move downwards and upwards through the winch system, while also enabling the drill rod 10 to rotate. It is precisely because the drill rod 10 undergoes rotation, upward movement, and downward movement that the position of the label 40 on the drill rod 10 is uncertain.

[0045] Example 2

[0046] like Figure 1 As shown, the drill pipe identification structure includes a drill pipe 10, a position detection device 20, and an identification device 30. The drill pipe 10 is configured to move within the oil and gas well 50, and a tag 40 is provided on the side wall of the drill pipe 10. The position detection device 20 is located on the inner wall of the oil and gas well 50. The position detection device 20 detects the position of the tag 40 and generates a corresponding position detection electrical signal. The identification device 30 is rotatably located at the wellhead of the oil and gas well 50. The identification device 30 receives the position detection electrical signal and rotates to face the tag 40 according to the position detection electrical signal to read the information of the tag 40.

[0047] As can be seen from the above, by setting a tag 40 on the drill pipe 10 to record the information of the drill pipe 10, the position detection device 20 detects the position of the tag 40 when the drill pipe 10 exits the well and generates a position detection electrical signal. The identification device 30 rotates to be directly opposite the tag 40 according to the position detection electrical signal, thereby successfully reading the information of the tag 40. Compared with the prior art, which relies on manual searching for the position of the tag 40, the present invention is time-saving, labor-saving and efficient, avoiding the situation where the tag 40 is missed due to the uncertainty of the position of the tag 40 during the process of the drill pipe 10 exiting the well, resulting in the tag 40 being missed. At the same time, since the drill pipe 10 carries a large amount of mud and sand when exiting the well, the automatic reading method of the identification device 30 in the present invention also ensures the safety of the operator's life and avoids safety accidents caused by close contact with the drill pipe 10 that is exiting the well. In addition, the coordinated operation of the tag 40, the position detection device 20 and the identification device 30 improves the accuracy and efficiency of wellhead identification of drill pipe 10, effectively fills the gap in information management of drill pipe 10 at the drilling site, provides a foundation for the full life cycle management of drill pipe 10, and the fully automated identification process also saves human resources.

[0048] It should be noted that the identification device 30 makes a circular motion around the wellhead of the oil and gas well 50, thereby changing the angle between it and the tag 40, and rotating it to be directly opposite the tag 40.

[0049] It should also be noted that the power to rotate the drill rod 10 is provided by the drilling rig. The drilling rig's function is to provide the power for the drill rod 10 to move downwards and upwards through the winch system, while also enabling the drill rod 10 to rotate. It is precisely because the drill rod 10 undergoes rotation, upward movement, and downward movement that the position of the label 40 on the drill rod 10 is uncertain.

[0050] In some embodiments, the position detection device 20 includes a ring vision sensor 210 and a first communication module 220; the ring vision sensor 210 is disposed on the inner wall of the oil and gas well 50, and is used to detect the position of the tag 40 and generate a corresponding position detection electrical signal; the first communication module 220 is disposed on the inner wall of the oil and gas well 50 and is electrically connected to the ring vision sensor 210, and is used to send the position detection electrical signal to the identification device 30.

[0051] The ring vision sensor 210 performs a blind-angle inspection of the outer wall of the drill rod 10, which improves the efficiency and accuracy of the inspection, quickly determines the position of the tag 40 and generates a position detection electrical signal; the first communication module 220 is used to realize the signal transmission.

[0052] It should be noted that the ring vision sensor 210 includes multiple sub-sensors, which are arranged circumferentially at equal intervals around the inner wall of the oil and gas well 50; the sub-sensors include, but are not limited to, laser scanners, CCD cameras, and cameras.

[0053] In some embodiments, the identification device 30 includes a turntable 310, a drive assembly, a reader 330, and a second communication module 340. The turntable 310 is rotatably disposed at the wellhead of the oil and gas well 50, and the turntable 310 is provided with a through hole for the drill pipe 10 to pass through. The drive assembly is disposed at the wellhead of the oil and gas well 50, and the drive assembly drives the turntable 310 to rotate. The reader 330 is disposed inside the turntable 310, and the reader 330 is used to read the information of the tag 40. The second communication module 340 is disposed inside the turntable 310 and electrically connected to the drive assembly, and the second communication module 340 is used to receive position detection electrical signals and transmit them to the drive assembly.

[0054] The drive assembly and turntable 310 provide the structural basis for the rotation of the reader 330. The drive assembly determines the rotation angle based on the position detection electrical signal, thereby rotating the reader 330 to face the tag 40, so as to ensure that the information of the tag 40 can be read smoothly.

[0055] It should be noted that the drive assembly includes a motor, and the drive assembly also includes a gear transmission mechanism or belt transmission mechanism connected to the turntable 310. The motor drives the gear transmission mechanism or belt transmission mechanism to rotate, thereby driving the turntable 310 to rotate.

[0056] It should also be noted that the number of readers 330 is at least one. When there are multiple readers 330, the multiple readers 330 are arranged at equal intervals around the turntable. After the drive component receives the position detection electrical signal, it drives the turntable to rotate so that one of the readers 330 is facing the tag 40.

[0057] In some embodiments, the first communication module 220 is a Bluetooth transmitting device, and the second communication module 340 is a Bluetooth receiving device.

[0058] Bluetooth signal transmission is fast and stable, and does not require a network, making it suitable for use on drilling sites.

[0059] In some embodiments, tag 40 is an RFID tag 40, and reader 330 is an RFID reader 330.

[0060] By adopting RFID technology, the usage of drill pipe 10 can be monitored, thereby improving the utilization rate of drill pipe 10 resources.

[0061] It should be noted that RFID (radio-frequency identification) is a non-contact automatic identification technology that reads electronic codes embedded in tags 40 of objects using radio frequency signals. Compared with technologies such as barcodes and QR codes, it has advantages such as fast reading speed, long working distance, and strong adaptability to working environments.

[0062] It should also be noted that users can pre-enter information into label 40 as needed, including but not limited to the model and grade of drill pipe 10.

[0063] In some embodiments, the position detection device 20 further includes a first power supply module 230 disposed on the inner wall of the oil and gas well 50, the first power supply module 230 being electrically connected to the ring vision sensor 210 and the first communication module 220 respectively.

[0064] By setting the first power supply module 230 to supply power to the position detection device 20, the normal operation of the position detection device 20 is ensured.

[0065] In some embodiments, the identification device 30 further includes a second power supply module 350 disposed in the turntable 310, the second power supply module 350 being electrically connected to the drive assembly, the reader 330 and the second communication module 340 respectively.

[0066] By setting a second power supply module 350 to supply power to the identification device 30, the second power supply module 350 rotates together with the turntable 310 to ensure the normal operation of the identification device 30.

[0067] Example 3

[0068] like Figure 2 As shown, this embodiment of the invention provides an identification method applied to the drill pipe identification structure as described in any of the preceding embodiments, thereby achieving all the technical effects brought about by the technical solutions of the above embodiments.

[0069] In some embodiments, the identification method includes:

[0070] S101: The position of the label 40 is detected by the position detection device 20 to obtain the first deflection angle;

[0071] It should be noted that the position of the tag 40 when the drill pipe 10 enters the wellhead of the oil and gas well 50 is recorded as the initial tag position; the first deflection angle is the angle between the position of the tag 40 when the drill pipe 10 exits the wellhead and the initial tag position; if rotating the drill pipe 10 counterclockwise by the first deflection angle can return the tag 40 to the initial tag position, then the first deflection angle is a positive value; if rotating the drill pipe 10 clockwise by the first deflection angle can return the tag 40 to the initial tag position, then the first deflection angle is a negative value; in addition, the absolute value of the first deflection angle is not greater than 180°.

[0072] S102: Based on the first deflection angle, obtain the second deflection angle;

[0073] It should be noted that when the drill pipe 10 enters the wellhead of the oil and gas well 50, the angle between the position of the tag 40 and the reader 330 is the initial deflection angle. When there are multiple readers 330, the reader 330 closest to the tag 40 when the drill pipe 10 enters the wellhead of the oil and gas well 50 is designated as the target reader, and the initial deflection angle is the angle between the position of the tag 40 and the target reader. Furthermore, the absolute value of the initial deflection angle is no greater than 180° / n, where n is the number of readers. For example, when there is only one reader 330, the absolute value of the initial deflection angle is no greater than 180°.

[0074] If rotating the drill rod 10 counterclockwise by the initial deflection angle can bring the tag 40 to the position of the reader 330, then the initial deflection angle is a positive value; if rotating the drill rod 10 clockwise by the initial deflection angle can bring the tag 40 to the position of the reader 330, then the initial deflection angle is a negative value.

[0075] It should also be noted that when the drill pipe 10 enters the wellhead of the oil and gas well 50, the reader 330 that is closest to the tag 40 is designated as the target reader. The second deflection angle is the angle between the position of the tag 40 and the target reader when the drill pipe 10 leaves the wellhead of the oil and gas well 50. The second deflection angle is the sum of the first deflection angle and the initial deflection angle.

[0076] For example, if both the first deflection angle and the initial deflection angle are greater than 0, then the second deflection angle is the sum of the first deflection angle and the initial deflection angle.

[0077] If both the first deflection angle and the initial deflection angle are less than 0, then the second deflection angle is the sum of the first deflection angle and the initial deflection angle.

[0078] If the first deflection angle is greater than 0 and the initial deflection angle is less than 0, and the absolute value of the first deflection angle is greater than that of the initial deflection angle, then the second deflection angle is the sum of the first deflection angle and the initial deflection angle.

[0079] If the first deflection angle is greater than 0 and the initial deflection angle is less than 0, and the first deflection angle is less than the absolute value of the initial deflection angle, then the second deflection angle is the sum of the first deflection angle and the initial deflection angle.

[0080] If the first deflection angle is less than 0 and the initial deflection angle is greater than 0, and the absolute value of the first deflection angle is less than the initial deflection angle, then the second deflection angle is the sum of the first deflection angle and the initial deflection angle.

[0081] If the first deflection angle is less than 0 and the initial deflection angle is greater than 0, and the absolute value of the first deflection angle is greater than the initial deflection angle, then the second deflection angle is the sum of the first deflection angle and the initial deflection angle.

[0082] S103: Rotate the identification device 30 by the second deflection angle so that the identification device 30 is facing the label 40;

[0083] It should be noted that when the second deflection angle is positive, the drill pipe 10 rotates clockwise; when the second deflection angle is negative, the drill pipe 10 rotates counterclockwise.

[0084] S104: Read the information of tag 40 through identification device 30.
