Description

Technical Field

[0001] The invention relates to the technical field of oil exploitation, in particular to an automatic well repairing machine. Background Art

[0002] In today's era of globalization and rapid technological development, a stable supply of energy is the cornerstone of a country's economic prosperity and social progress. As one of the most important energy sources in the world today, the efficiency and safety of oil extraction are directly related to a country's energy strategy, economic stability and environmental sustainability. With the continuous exploitation of oil resources, the difficulty of extraction is gradually increasing, especially under some complex geological conditions. Traditional well repair operations mainly rely on manual operations, which not only means that workers need to endure heavy physical labor, but also leads to low operating efficiency and increased safety risks.

[0003] It can be seen from the above-mentioned workover rig that the following defects still exist:

[0004] 1. When the workover rig pulls out the tubing, the bottom clamp will be sleeved on the outer surface of the tubing to prevent it from shaking. Since the clamp moves upward in a straight line when it is sleeved inside the tubing, the surface where the inner side of the clamp contacts the outer surface of the tubing rises vertically, which will cause the positions on both sides of the outer surface of the tubing to be rubbed and squeezed for a long time, thereby aggravating the wear on both sides, affecting the service life of the tubing and subsequent use effects. In addition, the outer surface of the tubing rubs against the same place on the inner side of the clamp for a long time, making the replacement and maintenance of the clamp more frequent.

[0005] 2. After the workover rig removes the tubing, it places it on one side through the tubing collector. Since the tubing is mixed together, the staff needs to screen and sort the removed tubing, which increases the workload and time cost and reduces the overall operation efficiency. In addition, when the tubing collector slides the tubing from the upper surface, due to the heavy weight of the tubing, the tubing will roll on the guide rail at a high speed, which will cause scratches, dents or even ruptures on the outer surface of the tubing, affecting the internal structure and performance of the tubing.

[0038] The upper surface of the arc plate 213 is fixedly connected to the fixed plate 22, the upper surface of the fixed plate 22 is fixedly connected to the limiting frame 221, the inner side of the limiting frame 221 is slidably connected to the trigger bar 222, one end of the trigger bar 222 close to the inner side of the limiting frame 221 is fixedly connected to the first spring 223, the side of the first spring 223 away from the trigger bar 222 is fixedly connected to the inner side of the limiting frame 221, the outer surfaces of both ends of the trigger bar 222 are slidably connected to the sliding sleeve 224, the upper surface of the sliding sleeve 224 is rotatably connected to the first connecting bar 23, and the first The lower surface of the connecting bar 23 away from the sliding sleeve 224 is rotatably connected to the upper surface of the limit frame 221, the lower surface of the sliding sleeve 224 is rotatably connected to the second connecting bar 231, the upper surface of the second connecting bar 231 away from one end of the sliding sleeve 224 is rotatably connected to the sliding bar 232, the outer surface of the sliding bar 232 is slidably connected to the inside of the limit frame 221, the inner side of the sliding bar 232 away from one end of the limit frame 221 is fixedly connected to the arc bar 233, and the upper surface of the sliding bar 232 close to the arc bar 233 is detachably connected to the detector 234.

[0039] The effects of this embodiment are as follows: In the prior art, when the well repair machine pulls out the oil pipe, the bottom clamp will be sleeved on the outer surface of the oil pipe to prevent the oil pipe from shaking. Since the clamp moves upward in a straight line when it is sleeved inside the oil pipe, the surface where the inner side of the clamp contacts the outer surface of the oil pipe rises vertically, which will cause the positions on both sides of the outer surface of the oil pipe to be subjected to long-term friction and compression, thereby aggravating the wear of these two sides, affecting the service life of the oil pipe and the subsequent use effect. Compared with the prior art, when the pipe remover 13 slides backward, it drives the trigger bar 222 to slide toward the outer surface of the oil pipe, so that the arc The arc strip 233 can be sleeved on the outer surface of the oil pipe, which can ensure that the oil pipe is stably grasped and stabilized during the extraction process, avoiding operational errors caused by shaking or sliding of the oil pipe, and the driving wheel 211 can drive the arc strip 233 to rotate on the outer surface of the oil pipe, avoiding the inner wall of the arc strip 233 from rubbing against the two ends of the outer surface of the oil pipe for a long time, so that the contact point with the inner wall of the arc strip 233 will continue to change during the extraction process of the oil pipe. When the arc strip 233 rotates, it will also drive the detector 234 to rotate at the same time, so that the state of the outer surface of the oil pipe can be detected in real time from all directions and angles.

[0040] refer to Figures 5 to 7As shown, an automated well repair machine is shown, the bottom of the pipe puller 12 is fixedly connected to a fixing frame 31, the upper surface of the fixing frame 31 is provided with a U-shaped groove, the inner side of the bottom of the fixing frame 31 is fixedly connected to a cylinder 311, and the cylinder 311 is controllably electrically connected to the detector 234, the upper surface of the output shaft of the cylinder 311 is slidably connected to the U-shaped groove provided on the upper surface of the fixing frame 31, the upper surface of the fixing frame 31 is slidably connected to a rack 312, the lower surface of the rack 312 is fixedly connected to the upper surface of the output shaft of the cylinder 311, and the upper surface of the fixing frame 31 is far away A limit plate 313 is symmetrically fixedly connected to one side of the rack 312, and a gear 314 is rotatably connected to the upper surface of the limit plate 313. The upper surface of the gear 314 close to the limit plate 313 is clamped with a limit bar 315, and the outer surface of the top of the limit bar 315 is slidably connected to the inside of the limit plate 313. The bottom of the limit bar 315 close to the gear 314 is fixedly connected to the outer surface of the rack 312. The end of the gear 314 close to the limit plate 313 is fixedly connected to a flip plate 316, and the lower surface of the flip plate 316 fits the upper surface of the tube collector 15.

[0041] The upper surface of the auxiliary platform 14 is fixedly connected to a support plate 32, and both ends of the top of the support plate 32 are rotatably connected to a first transmission rod 321, and the inner side of the first transmission rod 321 away from one end of the support plate 32 is rotatably connected to a takeover platform 322, and the outer surface of the takeover platform 322 close to the first transmission rod 321 is rotatably connected to a second transmission rod 323, and the second transmission rod 323 is rotatably connected to the outer surface of the support plate 32 on one side close to the outer surface of the takeover platform 322, and the bottom of the second transmission rod 323 is rotatably connected to a connecting rod 324, and the connecting rod 324 is close to the second transmission rod The outer surface of one side of 323 is fixedly connected with a second spring 325, the bottom of the second spring 325 is fixedly connected to the upper surface of the auxiliary platform 14, the bottom of the connecting rod 324 away from the second transmission rod 323 is rotatably connected to the sliding rod 33, the outer surface of the sliding rod 33 is slidably connected to the upper surface of the auxiliary platform 14, the inner side of the sliding rod 33 away from the end of the connecting rod 324 is rotatably connected with a rotating plate 331, the rotating plate 331 is rotatably connected to the axis of the side away from the sliding rod 33, and the bottom of the wedge-shaped platform 332 is fixedly connected to the upper surface of the auxiliary platform 14.

[0042] The effects of this embodiment are as follows: In the prior art, after the well repair machine removes the oil pipe, it places the oil pipe on one side through the pipe collector 15. Since the oil pipes are mixed together, the staff needs to screen and classify the removed oil pipes, which increases the workload and time cost and reduces the overall operation efficiency. In addition, if the damaged oil pipe is not identified and handled in time, it is easy to be misused, resulting in oil pipe leakage and breakage. Compared with the prior art, the cylinder 311 is extended and contracted to drive the flip plate 316 to flip left and right, so that the good oil pipe can be moved to the left side of the flip plate 316, and the damaged oil pipe can be moved to the right side of the flip plate 316, and the oil pipe can be classified and processed. At this time, the staff can immediately mark or process the damaged oil pipe to avoid the trouble of subsequent re-classification, and can also prevent the oil pipe from being confused and misused. When the flip plate 316 flips the oil pipe left and right, the oil pipe will fall into the receiving platform 322 to buffer the oil pipe from falling.

[0043] The complete working principle and steps of the above embodiment are as follows:

[0044] Anti-sway stability test steps:

[0045] like Figures 1 to 4 As shown, when the workover machine is in the initial state, the pipe puller 12 and the pipe remover 13 are both in the closed state, the first spring 223 is in a naturally relaxed state, the sliding sleeve 224 is slidably connected to the two ends of the outer surface of the trigger bar 222, and the arc bar 233 is in the expanded state;

[0046] When the staff uses the well repair machine, first start the pipe puller 12, so that the pipe puller 12 descends to clamp the oil pipe on the upper surface of the workbench 1 and moves upward. At this time, start the pipe remover 13, and the pipe remover 13 will slide to the side away from the oil pipe. As the pipe remover 13 slides on the upper surface of the workbench 1, it will drive the sliding table 21 fixedly connected to the right side of the pipe remover 13 to slide at the same time, so that the sliding table 21 slides toward the outer surface of the oil pipe. When the sliding table 21 slides, it will drive the driving wheel 211 rotatably connected to the upper surface of the sliding table 21 to slide at the same time. The driving wheel 211 is connected to the outer surface of the arc plate 213 through the synchronous belt 212. As the limit frame 221 slides, it drives the arc plate 213 to slide at the same time, and the arc plate 213 moves toward the outer surface of the oil pipe. When the surface slides, the fixing plate 22 drives the limiting frame 221 fixedly connected to the upper surface of the fixing plate 22 to slide at the same time. As the limiting frame 221 slides, the trigger bar 222 slidably connected to the inside of the limiting frame 221 is driven to slide at the same time. As the trigger bar 222 slides, the side of the trigger bar 222 away from the limiting frame 221 touches the outer surface of the oil pipe. At this time, when the trigger bar 222 then slides toward the side close to the oil pipe, the trigger bar 222 slides toward the side away from the oil pipe on the inner side of the limiting frame 221. When the trigger bar 222 slides, the first spring 223 fixedly connected to the left side of the trigger bar 222 is squeezed into a compressed state. When the trigger bar 222 slides, it also drives the sliding sleeves at both ends of the outer surface of the trigger bar 222. The upper surface of the sliding sleeve 224 is rotatably connected to the upper surface of the limiting frame 221 through the first connecting strip 23. At this time, when the trigger bar 222 moves toward the side close to the first spring 223, the sliding sleeves 224 on the outer surfaces of both ends of the trigger bar 222 will move toward the center of the outer surface of the trigger bar 222. As the sliding sleeve 224 moves toward the center of the trigger bar 222, the second connecting strip 231 connected to the bottom of the sliding sleeve 224 will be rotated to drive the sliding bar 232 to move at the same time, so that the sliding bar 232 slides inside the limiting frame 221 toward the center of the trigger bar 222. The inner side of the sliding bar 232 away from the end of the trigger bar 222 is fixedly connected to the outer surface of the arc strip 233. As the sliding bar 232 moves toward the center of the trigger bar 222, When the center of the spring 222 slides, the arc strip 233 is driven to slide at the same time, so that the inner wall of the arc strip 233 can fit the outer surface of the oil pipe, and the sliding bar 232 slides and also drives the detector 234 on the upper surface of the sliding bar 232 to move at the same time. When the pipe puller 12 drives the oil pipe to be lifted upward, the inner side of the arc strip 233 will be sleeved on the outer surface of the oil pipe to ensure that the oil pipe is stably grasped and fixed during the pulling process, avoiding operational errors caused by shaking or sliding of the oil pipe. Since the shape of the arc strip 233 is arc-shaped, this design can better fit the outer surface of the oil pipe and form a stable grip. This design reduces the risk of sliding and falling off due to shape mismatch, and when the arc strip 233 is sleeved on the outer surface of the oil pipe,At this time, when the pipe puller 12 drives the oil pipe to slide upward, the bottom of the arc strip 233 can scrape the residue on the outer surface of the oil pipe, reducing the residual time of these harmful substances and slowing down the corrosion rate of the oil pipe. When the arc strip 233 scrapes the residue, the detector 234 on the upper surface of the sliding strip 232 can contact the actual surface of the oil pipe more clearly, thereby improving the accuracy of the detection.

[0047] As the arc strip 233 is sleeved on the outer surface of the oil pipe, the driving wheel 211 on the upper surface of the sliding table 21 can be started. As the driving wheel 211 rotates, the synchronous belt 212 on the outer surface of the driving wheel 211 is driven to transmit simultaneously. As the synchronous belt 212 transmits, the arc plate 213 connected to the outer surface of the synchronous belt 212 is driven by friction, so that the arc plate 213 rotates on the upper surface of the sliding table 21. As the arc plate 213 rotates, the sliding strip 232 is driven to rotate inside the limit frame 221 through the fixed plate 22 on the upper surface. When the sliding strip 232 rotates, it drives the arc strip 233 to rotate on the outer surface of the oil pipe, which can ensure that the arc plate 213 can rotate from each side. The oil pipe is scraped at an angle, thereby removing the residue on the oil pipe more thoroughly and making the wear of the arc strip 233 more even. Compared with the fixed arc strip 233, the rotating arc strip 233 will not continuously scrape the same side of the oil pipe during the scraping process, thereby reducing the risk of damage to the clamp due to local excessive wear. When the detector 234 rotates on the outer surface of the oil pipe, it can ensure that there is no blind spot when the detector 234 detects the outer surface of the oil pipe, so that the detector 234 can more accurately detect defects on the outer surface of the oil pipe. At this time, when the pipe puller 12 pulls the oil pipe out from the bottom, the pipe remover 13 will move to the side close to the oil pipe and unscrew the oil pipe.

[0048] Automatic sorting buffer steps:

[0049] like Figures 5 to 7 As shown, when the workover machine is in the initial state, the pipe collector 15 is in the closed state, the cylinder 311 is in the semi-contracted state, the outer surface of the gear 314 has not yet meshed with the upper surfaces of the two ends of the rack 312, the upper surface of the limit bar 315 is clamped on the side of the gear 314 close to the limit plate 313, the second spring 325 is in a naturally relaxed state, and the outer surface of the rotating plate 331 is not in contact with the inside of the pipe connection platform 322;

[0050] As the tube remover 13 unscrews the oil tube, the tube collector 15 is started and gradually moves upward. At this time, the tube puller 12 is loosened to make the oil tube fall into the upper surface of the tube collector 15, and the tube collector 15 drives the oil tube to gradually shrink downward. Since the detector 234 is electrically connected to the cylinder 311, when the appearance of the oil tube identified by the detector 234 is intact, the output shaft of the cylinder 311 will shrink, and the upper surface of the output of the cylinder 311 is fixedly connected to the bottom of the rack 312. As the output shaft of the cylinder 311 shrinks, the rack 312 is driven to slide to the right. As the rack 312 slides to the right on the upper surface of the fixing frame 31, the gear 314 on the left is meshed with the upper surface of the rack 312, causing the gear 314 on the left to rotate counterclockwise inside the limit plate 313, and the rack 312 will drive the limit bar 315 on the left to move closer to the inner side of the limit plate 313 while moving to the right. When the oil pipe 15 is moved upward, the two sides of the turning plate 316 are clamped in the inner part of the limiting plate 313, thereby preventing the oil pipe 15 from falling off due to the turning of the turning plate 316.

[0051] When the oil pipe flips to the left on the upper surface of the flip plate 316, the oil pipe will slide into the inside of the connecting platform 322, and the outer surface of the oil pipe is rotatably connected to the outer surface of the supporting plate 32 through the first transmission rod 321. Due to the weight of the oil pipe, the connecting platform 322 will slide downward. As the connecting platform 322 slides downward, the second transmission rod 323 connected to the two ends of the connecting platform 322 will be driven to swing at the same time, which will cause the second transmission rod 323 to swing upward away from the end of the connecting platform 322. As the second transmission rod 323 swings upward, it will also drive the connecting rod 324 connected to the bottom of the second transmission rod 323 to move upward at the same time. At this time, the second spring 325 on the outer surface of the connecting rod 324 is pulled into a stretched state as the connecting rod 324 moves. As the connecting rod 324 moves upward, it will drive the sliding rod 33 connected to the bottom of the connecting rod 324 to move closer to the second spring The first and second ends of the second spring 325 are connected to the second end of the second spring 325, and the second end of the second spring 325 is connected to the second end of the second spring 325. The second end of the second spring 325 is connected to the second end of the second spring 325, and the second end of the second spring 325 is connected to the second end of the second spring 325. The second end of the second spring 325 is connected to the second end of the second spring 325, and the second end of the second spring 325 is connected to the second end of the second spring 325. The second end of the second spring 325 is connected to the second end of the second spring 325, and the second end of the second spring 325 is connected to the second end of the second spring 325. The second end of the second spring 325 is connected to the second end of the second spring 325, and the second end of the second spring 325 is connected to the second end of the second spring 325. The second end of the second spring 325 is connected to the second end of the second spring 325, and the second end of the second spring 325 is connected to the second end of the second spring 325.
