Description

Technical Field

[0001] This utility model relates to the field of drilling technology, and in particular to a borehole device. Background Technology

[0002] In current oil drilling logging operations, integrated wellbore cleaning and logging (BD) technology is commonly used to improve operational efficiency and reduce overall costs. This technology integrates wellbore cleaning and logging parameter acquisition into a single drilling run, aiming to simultaneously complete wellbore cleaning and downhole data acquisition, thereby avoiding the efficiency losses caused by repeated tripping in traditional step-by-step operations. The successful implementation of BD technology is highly dependent on the quality of the drill string caliper. According to API SPEC 5DP standards, the drill pipe inner diameter must be checked with a caliper gauge to ensure a caliper ≥95% to eliminate obstructions to logging instruments caused by internal scale, burrs, or local deformation, preventing jamming or signal transmission interruption during the descent of the logging instruments. In severe cases, this can lead to time-consuming and high-risk retrieval operations.

[0003] In related technologies, a gauging gauge is placed inside the drill pipe. During the descent of the gauging gauge, it may fail to detect the gauging gauge due to damage. The gauging gauge failure can only be verified after the entire drill pipe has been pulled out. Utility Model Content

[0004] This invention provides a gauging device for determining whether gauging detection is effective.

[0005] In a first aspect, this utility model provides a tube fitting device, comprising: A gauge, which is used to be inserted into the drill string and moved downward during tripping operations, wherein the drill string includes a connected drill pipe and a drill bit; A transmitting device is disposed on the gauging gauge and is used to transmit a preset signal; A receiving device, electrically connected to the transmitting device, is used to receive the preset signal to determine whether the path detection is effective.

[0006] In some embodiments, the gauge is a cylindrical structure, and multiple guide holes are provided on the side and both ends of the gauge, all of which are connected to the receiving cavity. In some implementations, it also includes: A first fixing pin is disposed radially within the receiving cavity along the bore gauge, and the first fixing pin abuts against the first end of the transmitting device to support the transmitting device. A jacket, the jacket being fitted onto the second end of the transmitting device; and The second fixing pin is connected to the jacket and the gauge.

[0007] In some embodiments, the first end is adjacent to the middle of the gauge, and the second end is adjacent to the end of the gauge; the gauge device further includes: A fixing block, the fixing block abutting against the second end; and A connector that connects the fixing block to the clamp.

[0008] Secondly, this application also provides a path detection method, including the aforementioned path detection device.

The receiving device and the alarm module are both electrically connected to the control module, and the judgment module is electrically connected to the alarm module. The path detection method includes: The control module controls the alarm module to execute the corresponding alarm mode based on whether the preset signal received by the receiving device is a normal signal or an abnormal signal; The judgment module determines whether the path detection is effective based on the alarm method.

[0009] In some implementations, if the preset signal received by the receiving device is a normal signal, the control module controls the alarm module to execute a first alarm mode, and the judgment module determines that the path detection is valid based on the first alarm mode.

[0010] In some implementations, after the determination module determines that the path detection is valid based on the first alarm method, it further includes: The judgment module determines whether the gauge passes the test based on the first preset condition. The judgment module determines that the gauge test failed based on the second preset condition.

[0011] In some implementations, the first preset condition is that the gauge is pulled out of the drill platform and the drill bit is pulled out of the drill platform.

[0012] In some implementations, the second preset condition is that the gauge is raised off the drilling platform and a portion of the drill pipe is inside the well.

[0013] In some implementations, if the preset signal received by the receiving device is an abnormal signal, the control module controls the alarm module to execute a second alarm mode, and the judgment module determines that the path detection is invalid based on the second alarm mode.

[0018] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0019] In this application, the terms "installation," "setup," "equipped with," "connection," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0020] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, components, or parts (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, components, or parts. Unless otherwise stated, "a plurality of" means two or more.

[0021] The technical solution of this application will be further described below with reference to specific embodiments and accompanying drawings.

[0022] Please refer to the following: Figure 1 , Figure 2 and Figure 3 In a first aspect, embodiments of this application provide a gauging device 1, including a gauging gauge 11, a transmitting device 12, and a receiving device 13. The gauging gauge 11 is deployed inside the drill string and descends during tripping operations, wherein the drill string includes a connected drill pipe and a drill bit, and the gauging gauge is provided with a receiving cavity 111. The transmitting device 12 is disposed within the receiving cavity 111 and is used to transmit a preset signal. The receiving device 13 is electrically connected to the transmitting device 12 and is used to receive the preset signal to determine whether the gauging detection is valid.

[0023] During the tripping-out process, the gauge 11 is placed inside the drill string and descends within it. During this descent, the gauge 11 removes scale and burrs from the drill string's inner wall, ensuring the smooth operation of logging instruments for subsequent wellbore cleaning and logging parameter acquisition. This prevents the logging instruments from getting stuck inside the drill string. For example, if the gauge 11 passes from the drill pipe to the drill bit during tripping-out, it indicates that the gauging is complete, ensuring the logging instruments can descend smoothly within the drill string after subsequent tripping. If the gauge 11 gets stuck in the drill pipe, it means the drill pipe failed the gauge 11 test and needs to be replaced. Besides these situations, there is also the possibility that the gauge 11 may break or fail to pass the gauging test. Such failure can only be verified after all the drill pipe has been pulled out.

[0024] To address this issue, in this embodiment, a transmitting device 12 is installed within the receiving cavity 111 of the gauge 11. As the gauge 11 descends within the drill string, the transmitting device 12 continuously sends a preset signal to the receiving device 13. The receiving device 13 can determine the validity of the gauge detection based on this preset signal. Specifically, when the gauge 11 is damaged or fractured, the transmitting device 12 may be exposed outside the receiving cavity 111 or even separate from the gauge 11, causing it to collide directly with the wellbore and become damaged, resulting in an abnormal working state. Consequently, the preset signal received by the receiving device 13 from the transmitting device 12 is an abnormal signal. When the gauge 11 is intact and undamaged, the transmitting device 12 is contained within the receiving cavity 111 and protected by the gauge 11, operating normally. Consequently, the preset signal received by the receiving device 13 from the transmitting device 12 is a normal signal.

[0025] Therefore, in this embodiment of the application, a transmitting device 12 is provided inside the gauge 11, and a receiving device 13 receives the preset signal emitted by the transmitting device 12. The effectiveness of the gauge test can be determined without the need for the entire drill pipe to be pulled out, which can improve the efficiency of the gauge test and save the time and cost of the gauge test.

[0026] Please refer to the following: Figure 1 and Figure 2 In some embodiments, the gauge 11 is a cylindrical structure, and multiple guide holes 112 are provided on the side and both ends of the gauge 11, and the multiple guide holes 112 are all connected to the receiving cavity 111.

[0027] Among them, the gauging gauge 11 has a cylindrical structure. When the gauging gauge 11 falls inside the drill pipe, the outer wall of the gauging gauge 11 can clean the scale or burrs on the inner wall of the drill pipe, thus achieving the effect of cleaning the inner wall of the drill pipe.

[0028] Understandably, if a drill bit gets stuck during tripping, it is necessary to start the pump for circulation. This involves injecting mud into the drill pipe to increase the pressure inside the well and force the drill bit out of the stuck position. Since the gap between the gauge 11 and the inner wall of the drill pipe is very small, if the gauge 11 gets stuck inside the drill pipe and its outer wall lacks a guide hole 112, the gauge 11 will block the mud. To solve this problem, in this embodiment, multiple guide holes 112 connecting to the receiving cavity 111 are provided on the side and both ends of the gauge 11. When the pump is started for circulation, the guide holes 112 can guide the mud downwards, thus completing the pump circulation.

[0029] Among them, the diameter of the gauge 11 is approximately 68 mm, the length is approximately 600 mm, and the diameter of the guide hole 112 is approximately 5 mm.

[0030] Please continue reading. Figure 1 and Figure 2 In some embodiments, the gauging device 1 further includes a first fixing pin 161, a sleeve 162, and a second fixing pin (not shown in the figure). The first fixing pin 161 is disposed radially in the receiving cavity 111 along the gauging gauge 11, and the first fixing pin 161 abuts against the first end of the transmitting device 12 to support the transmitting device 12. The sleeve 162 is sleeved on the second end of the transmitting device 12, and the second fixing pin is connected to the sleeve 162 and the gauging gauge 11.

[0031] In this embodiment of the application, when the gauge 11 is inserted into the drill pipe, the first end of the launching device 12 is located below the second end of the launching device 12. That is, the first fixing pin 161 is located below the second fixing pin. The first fixing pin 161 abuts against the launching device 12 and supports the launching device 12. The sleeve 162 is sleeved on the second end of the launching device 12. The second fixing pin is connected to the sleeve 162 and the gauge 11, which can fix the launching device 12 in the radial direction of the gauge 11.

[0032] Please continue reading. Figure 1 and Figure 2 In some embodiments, the first end is near the middle of the gauge 11, and the second end is near the end of the gauge 11. The gauging device 1 also includes a fixing block 164 and a connector 165. The fixing block 164 abuts against the second end, and the connector 165 connects the fixing block 164 and the clamp 162.

[0033] The fixing block 164 abuts against the second end, and the connecting piece 165 connects the fixing block 164 to the clamp 162, so that the fixing block 164 and the first fixing pin 161 clamp the transmitting device 12, which can fix the transmitting device 12 in the axial direction of the gauge 11 and prevent the transmitting device 12 from popping out from the end of the gauge 11.

[0034] Please see Figure 3 Secondly, embodiments of this application also provide a method for detecting the bore diameter of a bore diameter device 1, wherein the bore diameter device 1 further includes an alarm module 14, a control module 15, and a judgment module 17. The receiving device 13 and the alarm module 14 are both electrically connected to the control module 15, and the judgment module 17 is electrically connected to the alarm module 14.

[0035] Please see Figure 4 The methods for detecting the duct diameter include: S100: The control module 15 controls the alarm module 14 to execute the corresponding alarm mode based on whether the preset signal received by the receiving device 13 is a normal signal or an abnormal signal.

[0036] S200: Judgment module 17 determines whether the path detection is effective based on the alarm method.

[0037] The alarm module 14 may include a buzzer and a strobe light. When an alarm is triggered, the buzzer and strobe light of the alarm module 14 will work. The buzzer transmits an auditory signal through sound waves, and the strobe light transmits a visual signal through light waves. This can improve the warning effect on the staff in noisy drilling sites and help the staff to make a quick response.

[0038] The preset signal received by the receiving device 13 is a normal signal, which can be an electromagnetic signal of a preset frequency emitted by the transmitting device 12 that the receiving device 13 receives within a threshold time. For example, the threshold time is 5 seconds, and the preset signal emitted by the transmitting device 12 can be a dual-frequency electromagnetic signal of 2.4GHz / 433MHz.

[0039] In some implementations, if the preset signal received by the receiving device 13 is a normal signal, the control module 15 controls the alarm module 14 to execute the first alarm mode, and the judgment module 17 determines that the path detection is valid according to the first alarm mode.

[0040] Among them, the alarm module 14 can perform the first alarm mode by having the buzzer emit a periodic sound and the strobe light flash continuously.

[0041] In this embodiment, when the gauge 11 is not damaged or broken, the transmitting device 12 is housed in the receiving cavity 111 and protected by the gauge 11, thus operating normally. The receiving device 13 receives a preset signal emitted by the transmitting device 12, which is a normal signal. The receiving device 13 generates a normal command and transmits it to the control module 15. After receiving the normal command, the control module 15 generates a first alarm command and transmits it to the alarm module 14. The alarm module 14 executes a first alarm mode according to the first alarm command. After executing the first alarm mode according to the first alarm command, the alarm module 14 can generate an executed first alarm signal and transmit it to the judgment module 17. The judgment module 17 determines that the gauge detection is valid based on the executed first alarm signal.

[0042] In some implementations, after the determination module 17 determines that the path detection is valid based on the first alarm method, it further includes: The judgment module 17 determines that the gauge must pass the test based on the first preset condition.

[0043] The judgment module 17 determines that the gauge test has failed based on the second preset condition.

[0044] A valid gauging test indicates that the gauging gauge 11 is not damaged or broken and can perform normal gauging operations. Therefore, based on the determination that the gauging test is valid, the judgment module 17 can further determine whether the gauging gauge 11 has passed the test according to a first preset condition, or determine whether the gauging gauge 11 has failed the test according to a second preset condition. Passing the gauging gauge 11 test means that the gauging gauge 11 falls to the position of the drill bit connected to the bottom of the drill pipe during the gauging operation; failing the gauging gauge 11 test means that the gauging gauge 11 gets stuck at a certain position in the middle of the drill pipe during the gauging operation and fails to reach the position of the drill bit.

[0045] It should be noted that drill pipes are typically formed by connecting multiple rods in series, with the drill bit installed at the bottom of the lowest rod. When the drill bit passes through gauge 11, i.e., when gauge 11 completes the gauging operation, it will fall down to the drill bit; when the drill bit fails to pass through gauge 11, i.e., when gauge 11 has not completed the gauging operation, gauge 11 will usually be stuck inside one of the rods.

[0046] In some implementations, the first preset condition is that the gauge 11 is lifted out of the drilling platform and the drill bit is lifted out of the drilling platform.

[0047] When the gauging gauge 11 completes the gauging operation, it falls to the position of the drill bit connected to the bottom of the drill pipe. Therefore, if the drill bit also comes out of the drill platform just as the gauging gauge 11 is lifted out, it means that the gauging gauge 11 is in the position of the drill bit. This verifies that the gauging gauge 11 has completed the gauging operation, thus confirming that the gauging gauge 11 has passed the inspection.

[0048] Therefore, in this embodiment, based on the validity of the duct gauge detection and combined with the first preset condition, it can be determined not only that the duct gauge detection is valid, but also that the duct gauge 11 has passed the detection.

[0049] In some implementations, the second preset condition is that the gauge 11 is raised off the drilling platform and a portion of the drill pipe is inside the well.

[0050] When a drill pipe fails to pass the gauge 11 test, meaning the gauge 11 has not completed the gauging operation, it is typically stuck inside a member of the drill string. Therefore, if a portion of the drill string is still inside the well when the gauge 11 is pulled out of the drill platform, it indicates that the gauge 11 is stuck inside the member that was just pulled out. This verifies that the gauge 11 has not completed the gauging operation, confirming that the test has failed. In subsequent maintenance, only this member needs to be replaced, instead of the entire drill string, significantly improving drill string maintenance efficiency.

[0051] The aforementioned method for obtaining the gauge 11's position on the drilling surface can be implemented using various means. For example, the receiving device 13 can be positioned on the side of the wellhead, with the distance between the receiving device 13 and the wellhead approximately a preset distance. Simultaneously, the approximate straight-line distance between the transmitting device 12 and the receiving device 13 can be calculated using the time required for the transmitting device 12 to transmit the preset signal and for the receiving device 13 to receive the preset signal. The control module 1515 compares this straight-line distance with the preset distance to determine whether the transmitting device 12 has reached the drilling surface, thereby indirectly determining whether the gauge 11 has reached the drilling surface. Of course, other methods can also be used to determine whether the gauge 11 has reached the drilling surface, which are not limited here.

[0052] In some implementations, if the preset signal received by the receiving device 13 is an abnormal signal, the control alarm module 14 executes a second alarm mode. The judgment module 17 determines that the path detection is invalid based on the second alarm mode.

[0053] Among them, the second alarm mode executed by the alarm module 14 can be that the buzzer emits a continuous sound and the strobe light flashes continuously.

[0054] In this embodiment, when the gauge 11 is damaged or fractured, the transmitting device 12 is exposed in the receiving cavity 111 or separates from the gauge 11. The transmitting device 12 collides with the well wall and is in an abnormal working state. The receiving device 13 receives a preset signal emitted by the transmitting device 12, which is an abnormal signal. The receiving device 13 generates an abnormal command and transmits it to the control module 15. After receiving the abnormal command, the control module 15 generates a second alarm command and transmits it to the alarm module 14. The alarm module 14 executes a second alarm mode according to the second alarm command. After executing the second alarm mode according to the second alarm command, the alarm module 14 can generate an executed second alarm signal and transmit it to the judgment module 17. The judgment module 17 determines that the gauge detection is invalid based on the executed second alarm signal.

[0055] The abnormality of the preset signal received by the receiving device 13 from the transmitting device 12 can include situations where the received signal is continuously lost for a period exceeding a threshold, or the received preset signal is a signal from another frequency band. For example, the preset signal transmitted by the transmitting device 12 can be a dual-frequency electromagnetic signal of 2.4 GHz / 433 MHz. If the electromagnetic signal received by the receiving device 13 is another type of electromagnetic signal, it indicates that the received preset signal is abnormal. Alternatively, the abnormality of the received preset signal can also be due to the time during which the preset signal is not received exceeding a threshold time. In other words, the continuous loss time of the preset signal is greater than or equal to a threshold time. For example, if the threshold time is set to 5 seconds, and the time during which the receiving device 13 does not receive the preset signal is greater than or equal to 5 seconds, it indicates that the received preset signal is abnormal.

[0056] Although the present invention has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of the invention. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
