Description

Technical Field

[0001] This invention relates to the field of drilling rig testing technology. More specifically, this invention relates to a drill pipe anti-spinning system for rotary table drag testing of oil drilling rigs and its testing method. Background Technology

[0002] Before leaving the factory, oil drilling rigs typically undergo top drive and rotary table drag tests to measure the stress, strain, and displacement data of the derrick and verify its structural strength. During single-drill-pipe tests, the drill-pipe swing is minimal, allowing the test to proceed smoothly. However, during tests with two or three drill pipes, at higher torques and drilling speeds exceeding 40 rpm, the drill-pipe swing becomes significant, posing a risk of the drill pipe being ejected from the rotary table. To conduct top drive and rotary table drag tests under high torque and high speed conditions, it is necessary to control the drill-pipe swing during two or three-drill-pipe tests, further achieving the goal of verifying the derrick strength under high drilling speed and high torque conditions before the oil drilling rig leaves the factory. Summary of the Invention

[0003] One object of the present invention is to solve at least the above-mentioned problems and to provide at least the advantages that will be described later.

[0004] Another objective of this invention is to provide a drill pipe anti-swing system and its testing method for oil drilling rig rotary table dragging test, in order to solve the technical problem that the lack of protective measures to control drill pipe swing in existing drill pipe tests results in a limited range of performance tests.

[0005] To achieve these objectives and other advantages according to the present invention, in one aspect, the present invention provides a drill pipe anti-swing system for a rotary table dragging test of an oil drilling rig, comprising an anti-swing robotic arm mounted on a derrick, forming a test space between the inner side of the derrick and the lower platform plane, a top drive mounted on the top of the test space, a rotary table mounted on the platform plane corresponding to the plane position of the top drive, and a drill pipe mounted between the top drive and the rotary table. The anti-swing robotic arm includes a fixed end and a control end. The fixed end is detachably and fixedly connected to a crossbeam at a corresponding height on the derrick, and the control end has an arc-shaped groove facing the drill pipe side. The axial direction of the arc-shaped groove is parallel to the axial direction of the drill pipe, and the inner diameter of the arc-shaped groove is larger than the outer diameter of the drill pipe. Arc-shaped rings are detachably and fixedly connected to both ends of the arc-shaped groove, forming a vertically penetrating anti-swing cavity between the arc-shaped rings and the arc-shaped groove. The drill pipe passes downward through the anti-swing cavity so that the arc-shaped groove and the arc-shaped rings protect the drill pipe from swing when the drill pipe rotates at high speed.

[0006] Preferably, the two ends of the arc-shaped groove are respectively provided with two pairs of upper and lower slots, and the upper slot and the lower slot are spaced apart to form a slot. Each slot has a vertical through hole. The two ends of the arc-shaped ring are respectively provided with alignment holes through the axial direction. The two ends of the arc-shaped ring are used to insert into the slot, and after the alignment hole is aligned with the corresponding side insertion hole, a test pin is inserted and fixed together.

[0007] Preferably, the fixed end is configured as a C-shaped groove structure, the inner dimension of the C-shaped groove is configured to match the crossbeam of the derrick, and multiple pairs of screw holes are symmetrically opened on both sides of the C-shaped groove. Among them, a pair of screw holes are fitted on the outer side of the crossbeam. The anti-swing robotic arm is fixed to the crossbeam by screwing bolts into each pair of screw holes.

[0008] Preferably, multiple anti-swing robotic arms are arranged vertically, with at least one anti-swing robotic arm provided for each drill rod.

[0009] Preferably, the anti-swing robotic arm has a telescopic structure in the middle for adjusting the lateral distance relative to the drill rod.

[0010] On the other hand, the present invention also provides a test method for a drill pipe anti-spinning system for a rotary table drag test of an oil drilling rig, comprising the following steps: S1. Adjust the height of the top drive and install a drill rod, with the lower end of the drill rod aligned with the inside of the connecting turntable; S2. Install the anti-swing robotic arm using a crane, align the arc-shaped groove with the drill pipe, then connect the fixed end to the derrick, and finally install the arc-shaped ring on the opposite side of the arc-shaped groove. S3. Operate the speed button in the driller's cabin to increase the speed of the drill pipe driven by the top drive, and maintain the speed for 5 seconds to test the data; S4. Data testing completed. The anti-swing robotic arm was disassembled by a crane, and the test was completed.

[0011] Preferably, before step S3, a monitoring step A1 is also included: A1. A remote control terminal is installed in the driller's cabin. The remote control terminal is equipped with a calculation module, a prediction module, and an alarm module. Monitoring points are set at intervals along the vertical alignment parallel to the length of the drill pipe on the derrick. The uppermost monitoring point corresponds to the top center of the uppermost drill pipe. Each monitoring point is equipped with an amplitude detection sensor to detect the amplitude S of the drill pipe at its current height in real time. A height detection sensor is set at each amplitude detection sensor to detect the height distance L relative to the platform plane. The amplitude detection sensor and the height detection sensor are respectively connected to the remote control terminal for communication. While step S3 is being performed, the following steps are also included: A2. The calculation module calculates the angle of deviation from the vertical axis during the rotation of the drill rod based on the swing amplitude S and the height distance L relative to the platform plane of multiple detection points, eliminates defective data, and correlates time, rotation speed and / or torque to generate a change curve. A3. Each test generates a curve showing the change of swing amplitude over time at different speeds and / or torques. The prediction module predicts the maximum value of the swing amplitude at the next higher speed and / or torque. The swing amplitude threshold is set in the calculation module via a remote control terminal. If the swing amplitude threshold is exceeded, an alarm is issued through the alarm module.

[0012] Preferably, for test objects with multiple drill pipe extensions, a boom is connected between the fixed end and the control end of the anti-swing robotic arm. A lateral telescopic cylinder is connected between the boom and the arc-shaped groove to adjust the lateral position of the anti-swing chamber. A vertical telescopic cylinder is connected between the fixed end and the boom to adjust the vertical position of the anti-swing chamber. The lateral and vertical telescopic cylinders are respectively communicatively connected to the remote control terminal. The calculation module calculates the vertical distribution position of the anti-swing chambers corresponding to each drill pipe for anti-swing. Let the number of anti-swing robotic arms be n, the number of drill pipes be c, and the length of each drill pipe be l, then the setting height H of each anti-swing chamber is... n for Drive the horizontal telescopic cylinder and the vertical telescopic cylinder to adjust the anti-swing chamber to H. n It is located at its top drive center.

[0013] The present invention includes at least the following beneficial effects: The drill pipe anti-swing system and its testing method for the oil drilling rig rotary table drag test of the present invention sets an anti-swing mechanical arm on the outside of the drill pipe to be tested. After the drill pipe is installed between the top drive and the rotary table, the anti-swing mechanical arm is hoisted and fixed to the derrick beam. The arc-shaped groove is aligned with the drill pipe and the arc-shaped ring for temporary fixed connection, and the inner side together form an anti-swing cavity. Then the drill pipe is driven to rotate for testing, ensuring stable limit in the horizontal direction. By designing and setting the anti-swing mechanical arm, the swing of the drill pipe can be controlled, avoiding the drill pipe from leaving the drill table during high torque and high drilling speed tests, and the resulting safety risks. It realizes the inspection of complex working conditions of the drilling rig derrick, meets the requirements of multiple working conditions, and provides a more comprehensive assessment of the strength of the drilling rig derrick.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0018] It should be noted that, unless otherwise specified, the experimental methods described in the following embodiments are all conventional methods, and the reagents and materials described are all commercially available unless otherwise specified. In the description of this invention, the terms "lateral", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0019] like Figure 1-7As shown, this invention provides a drill pipe anti-swing system for rotary table dragging test of oil drilling rig, including an anti-swing robotic arm 1. The anti-swing robotic arm 1 is installed on the derrick, and a test space is formed between the inner side of the derrick and the lower platform plane 8. A top drive 6 is installed on the top of the test space. A rotary table 7 is installed on the platform plane 8 corresponding to the plane position of the top drive 6. A drill pipe 2 is installed between the top drive 6 and the rotary table 7. The anti-swing robotic arm 1 includes a fixed end 10 and a control end 11. The fixed end 10 is detachably fixedly connected to the crossbeam 3 at the corresponding height of the derrick. The control end 11 has an arc-shaped groove on the side facing the drill pipe 2. The axial direction of the arc-shaped groove is parallel to the axial direction of the drill pipe 2, and the inner diameter of the arc-shaped groove is larger than the outer diameter of the drill pipe 2. Arc-shaped rings 4 are detachably fixedly connected to both ends of the arc-shaped groove. A vertically penetrating anti-swing cavity is formed between the arc-shaped rings 4 and the arc-shaped groove. The drill pipe 2 passes downward through the anti-swing cavity so that when the drill pipe 2 rotates at high speed, the arc-shaped groove and the arc-shaped rings 4 protect the drill pipe 2 from swinging.

[0020] After the drill pipe 2 is installed between the top drive 6 and the rotary table 7, the anti-swing robotic arm 1 is hoisted, the arc-shaped groove is aligned with the drill pipe 2, and then it is connected to the derrick through the fixed end 10. Then, an arc-shaped ring 4 is fastened to the outside of the drill pipe 2 at one end of the arc-shaped groove, and temporarily fixed to the arc-shaped groove. Together, they form an anti-swing cavity. Then, the drill pipe 2 is driven to rotate for testing to ensure stable horizontal positioning. The inner diameter of the anti-swing cavity is larger than the outer diameter of the drill pipe 2 and the rotation. By setting the anti-swing robotic arm 1 of this application, a high drilling speed and high torque top drive 6 and rotary table 7 drag test can be carried out to meet the test conditions.

[0021] Without the tension of the underground drill rod 2 during the test, the swing amplitude of the drill rod 2 would be too large. The present invention can control the swing of the drill rod 2 by setting an anti-swing robotic arm 1, so as to avoid the drill rod 2 from detaching from the drill table during the test under high torque and high drilling speed conditions, and avoid the safety risks caused. It can realize the inspection of complex working conditions of the test drilling rig derrick and make the strength assessment of the drilling rig derrick more comprehensive.

[0022] In another technical solution, such as Figure 6-8 As shown, the two ends of the arc-shaped groove are respectively provided with two pairs of upper and lower slots. The upper slot and the lower slot are spaced apart to form a slot 12. Each slot has a vertically penetrating insertion hole 14. The two ends of the arc-shaped ring 4 are respectively provided with alignment holes 13 penetrating along the axial direction. The two ends of the arc-shaped ring 4 are used to insert into the slot 12. After the alignment hole 13 is aligned with the corresponding insertion hole 14, the test pin 5 is inserted and fixed together.

[0023] The slot 12 supports the arc ring 4, and the two test pins 5 on both sides of the arc groove are inserted into the corresponding slot 12 and the insertion hole 14 to form a radial limiting fixation, providing an anti-swing function on the outside of the drill rod 2.

[0024] In another technical solution, such as Figure 5As shown, the fixed end 10 is configured as a C-shaped groove structure. The inner dimensions of the C-shaped groove are matched with the crossbeam 3 of the derrick. Multiple pairs of screw holes 15 are symmetrically opened on both sides of the C-shaped groove. Among them, a pair of screw holes 15 are fitted on the outer side of the crossbeam 3. The anti-swing robotic arm 1 is fixed to the crossbeam 3 by screwing bolts into each pair of screw holes 15.

[0025] The C-shaped groove abuts against the inner side of the crossbeam 3. After the bolts near the side of the crossbeam 3 are screwed in, they abut against the outer side of the crossbeam 3 for limiting. Bolts are screwed into the other screw holes 15 of the C-shaped groove facing the top and bottom surfaces of the crossbeam 3 for locking, so as to temporarily fasten the fixed end 10 to the crossbeam 3 for easy disassembly and assembly.

[0026] In another technical solution, such as Figure 1-2 As shown, multiple anti-swing robotic arms 1 are arranged vertically, with at least one anti-swing robotic arm 1 corresponding to each drill rod 2. For tests involving multiple drill rods 2 or when the rotational speed is high, multiple anti-swing robotic arms 1 are set up, with corresponding design settings for height, spacing, etc., to meet the test safety requirements under complex working conditions of multiple drill rods 2.

[0027] In another technical solution, such as Figure 1-2 As shown, the anti-swing robotic arm 1 is provided with a telescopic structure in the middle, which is used to adjust the lateral distance relative to the drill rod 2. The telescopic length can be adapted to different drilling rig models and different heights of the derrick, thereby improving the flexibility of the anti-swing robotic arm 1 in installation and use.

[0028] This invention also provides a test method for a drill pipe anti-spinning system used in oil drilling rig rotary table dragging tests, combined with Figure 1-8 As shown, it includes the following steps: S1. Adjust the height of the top drive 6 and install a drill rod 2, with the lower end of the drill rod 2 aligned with the inside of the connecting turntable 7; S2. Install the anti-swing robotic arm 1 using a crane, align the arc groove with the drill pipe 2, then connect the fixed end 10 to the derrick, and then install the arc ring 4 on the opposite side of the arc groove. S3. Operate the speed button in the driller's cabin to increase the speed of the top drive 6 driving the drill pipe 2, and maintain the speed for 5 seconds to test the data; S4. Data testing completed. The anti-slip robotic arm 1 was disassembled by a crane, and the test was completed.

[0029] The test method for the anti-swing system of drill rod 2 used in the drag test of oil drilling rig rotary table 7 is to connect drill rod 2 to rotary table 7 through top drive 6, drive drill rod 2 to rotate at high speed to carry out multi-condition test. The multi-condition test includes test variables under different speed and different torque. An anti-swing robotic arm 1 is set up to avoid the risk of drill rod 2 being thrown off rotary table 7 during the test.

[0030] In another technical solution, such as Figure 1-2As shown, before step S3, a monitoring step A1 is also included: A1. A remote control terminal is installed in the driller's cabin. The remote control terminal is equipped with a calculation module, a prediction module, and an alarm module. Monitoring points are set at intervals on the derrick along the vertical alignment parallel to the length of the drill pipe 2. The uppermost monitoring point corresponds to the top center of the uppermost drill pipe 2. Each monitoring point is equipped with an amplitude detection sensor to detect the amplitude S of the drill pipe 2 at its current height in real time. A height detection sensor is set at each amplitude detection sensor to detect the height distance L relative to the platform plane 8. The amplitude detection sensor and the height detection sensor are respectively connected to the remote control terminal for communication. While step S3 is being performed, the following steps are also included: A2. The calculation module calculates the angle of deviation from the vertical axis during the rotation of drill rod 2 based on the swing amplitude S of multiple detection points and the height distance L relative to the platform plane 8, eliminates defect data, and correlates time, rotation speed and / or torque to generate a change curve. A3. Each test generates a curve showing the change of swing amplitude over time at different speeds and / or torques. The prediction module predicts the maximum value of the swing amplitude at the next higher speed and / or torque. The swing amplitude threshold is set in the calculation module via a remote control terminal. If the swing amplitude threshold is exceeded, an alarm is issued through the alarm module.

[0031] A detection and prediction system is set up to monitor and assess the potential risk of detachment during drill pipe 2 testing. If the swing amplitude continues to increase or even exceeds the threshold, an alarm is triggered directly. Alternatively, by monitoring the swing amplitude data in advance and predicting whether there is a risk of exceeding the threshold after increasing the rotation speed, the structure and connection status of drill pipe 2, top drive 6, rotary table 7, etc. are adjusted in a timely manner before the next test. This allows for more scientific drill pipe 2 drag tests under multiple and complex working conditions, thus improving the anti-detachment safety system.

[0032] In another technical solution, such as Figure 1-2 As shown in Figure 5, for a test object with multiple drill rods 2 extended, a boom 9 is connected between the fixed end 10 and the control end 11 of the anti-swing robotic arm 1. A horizontal telescopic cylinder is connected between the boom 9 and the arc-shaped groove to adjust the horizontal position of the anti-swing cavity. A vertical telescopic cylinder is connected between the fixed end 10 and the boom 9 to adjust the vertical position of the anti-swing cavity. The horizontal telescopic cylinder and the vertical telescopic cylinder are respectively connected to the remote control terminal. The calculation module calculates the vertical distribution position of the anti-swing cavity corresponding to each drill rod 2 for anti-swing. Let the number of anti-swing robotic arms 1 be n, the number of drill rods 2 be c, and the length of each drill rod 2 be l, then the setting height H of each anti-swing cavity is... n for Drive the horizontal telescopic cylinder and the vertical telescopic cylinder to adjust the anti-swing chamber to H. nThe center of the top drive is located at point 6.

[0033] Especially for drag tests involving multiple drill rods 2, multiple anti-swing robotic arms 1 are required to prevent detachment. The top drill rod 2 is close to the drive source, while the bottom has a larger swing amplitude. Therefore, by monitoring the swing amplitude of drill rods 2 at different positions, the state of each drill rod 2 can be scientifically evaluated. Furthermore, based on the test situation where the swing amplitude is larger at the bottom, the height of the anti-swing cavity of the anti-swing robotic arm 1 relative to the drill rod 2 can be adjusted, rather than being set at a single interval or fixed position. This allows for targeted protection under different working conditions, better addressing the kinetic energy resistance requirements at the corresponding height position of the drill rod 2, and achieving faster and better anti-detachment and mitigation of excessive swing.

[0034] Although embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for the present invention. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, the present invention is not limited to the specific details and illustrations shown and described herein.
