Description

Technical Field

[0001] The invention relates to the technical field of oil exploitation, in particular to a horizontal oil well scraper tool testing platform. Background Art

[0002] As China's oil and gas exploration and development moves towards low permeability, deep layers, offshore areas, and unconventional areas, the types of oil and gas reservoirs are diversified, the wellbore structure is complicated, and the safety and environmental protection requirements are strict. Well repair operations face new challenges, and the requirements for well repair tools are getting higher and higher. The quality improvement, quality assurance, technological progress, and technological innovation of well repair tools require countless tests, so the oil well repair tool test platform is becoming more and more important. However, there is no manufacturer in China that specializes in producing oil downhole scraper tool test platforms, which means that the tool manufacturers or oil fields that use the tools can only use the drilling platform to test the scraper tools at the drilling site or directly find a test well to test the scraper tools. Not only is the test cost extremely high, but the collected data is also inaccurate, which to a certain extent limits the development of domestic oil casing scraper tools.

[0003] Chinese patent publication number CN108150139B discloses "a downhole oil pipe clearing tool, belonging to the field of oil extraction technology. The downhole oil pipe clearing tool includes a variable buckle joint, a weight rod, a limit cap, a core shaft and a scraper head. The scraper head is provided with a cavity inside. The lower part of the variable buckle joint is connected to the upper part of the weight rod, and the lower part of the weight rod is connected to the upper part of the core shaft. The limit cap is sleeved on the outer wall of the core shaft, and the lower part of the limit cap is connected to the upper part of the scraper head. The core shaft is suitable for inserting into the cavity of the scraper head. The core shaft and the scraper head can rotate and axially displace relative to each other. The tool can be repeatedly lifted and lowered to achieve the effect of shocking and rotating shearing the heavy oil accumulated in the pipe string, so as to achieve the unblocking of the pipe string. The invention has a simple structure, reduces the occurrence rate of failures in the process of unblocking, and when the tool is stuck during the lifting process, the tool can be lifted out of the well by backwashing the well and repeatedly lifting the tool, thereby reducing the risk of the tool falling into the well."

[0004] During the conception process, the applicant searched a large number of patent documents on the patent network. For example, China Patent Publication No. CN108150139B discloses "a downhole oil pipe cleaning tool". The casing scraper is a tool used to remove cement, burrs, paraffin, etc. on the inner wall of the downhole casing. Due to its simple working principle and high test cost, most manufacturers do not conduct factory tests, resulting in the scraper shedding, scraper blade breakage, incomplete scraping or casing damage in the well, which increases the difficulty of subsequent well repair operations. The simulation test of the casing scraper is difficult and requires large push-pull force, high speed and high frequency. The power element, whether it is a servo motor, an actuator or a hydraulic push-pull cylinder, cannot fully meet the requirements. Because the development time of well repair technology in China is short, the use of well repair tools is relatively small. Therefore, the high cost and low return rate of the scraper tool test platform lead to the problem that there is no professional manufacturer of scraper test platform in China. Therefore, a horizontal oil downhole scraper tool test platform is proposed to solve the above-mentioned problems. Summary of the invention

The actuator 2 includes a life actuator and a push-pull actuator. The life actuator is used to test the service life of the scraper under different environments, and its characteristics are fast speed, high frequency, short stroke, and small push-pull force. The push-pull actuator is used to test scrapers of different models and sizes in casings with different thicknesses and different pollution degrees. The required force value is characterized by slow speed, large push-pull force, long stroke and long life. The actuator is fixedly connected to the upper surface of the frame 1, and the push-pull actuator is fixedly connected to the inner surface of the frame 1. The clamp 4 includes a servo motor 41, and the servo motor 41 is fixedly connected to the right surface of the frame 1. The output shaft of the servo motor 41 is fixedly connected with a screw rod 42. The upper surface of the frame 1 is fixedly connected with a guide rail 43, and the upper surface of the guide rail 43 is slidably connected with a clamping head 44. The clamping head 44 is more stable through the mutual cooperation of the guide rail 43 and the clamping head 44. The screw rod 42 penetrates the clamping head 44 and is threadedly connected to the clamping head 44. Through the cooperation of the screw rod 42 and the servo motor 41, the clamping head 44 can be driven to move, and the clamping head can be adjusted according to the length of the sleeve. 44 can be adjusted to ensure that sleeves of different sizes can be clamped. The upper surface of the clamping head 44 is penetrated by a fixing pin 45 and is slidably connected to the fixing pin 45. The upper surface of the frame 1 is provided with fixing holes 46 in a linear array. The fixing pin 45 is slidably connected to the fixing hole 46. Through the arrangement of the fixing pin 45 and the fixing hole 46, after the clamping head 44 reaches the specified position, the fixing pin 45 is inserted into the fixing hole 46 to realize the positioning of the clamping head 44. The inner surface of the clamping head 44 is rotatably connected to a bidirectional screw rod 47. The inner surface of the clamping head 44 is slidably connected to a tooth block 48. The bidirectional screw rod 47 can drive the two groups of tooth blocks 48 to separate or aggregate to both sides. The bidirectional screw rod 47 penetrates the tooth block 48 and is threadedly connected to the tooth block 48. Then, the inner surface of the tooth block 48 is provided with a groove 49, and the inner surface of the groove 49 is rotatably connected with a rotating shaft 410 in a circular array. The multiple sets of rotating shafts 410 are connected by transmission belt 1 411. A small motor 412 is fixedly connected to the right surface of the tooth block 48, and the output shaft of the small motor 412 is connected to the rotating shaft 410 by transmission belt 2. Through the arrangement of the small motor 412, the transmission belt 2 and the transmission belt 1 411, the transmission belt 1 411 can be driven to rotate around the rotating shaft 410. At the same time, the transmission belt 1 411 is in close contact with the outer arc surface of the sleeve, so that the sleeve can be driven to rotate. When the water output in the water tank 5 is small, the sleeve can be rotated to make the inner wall of the sleeve completely immersed in water to ensure the integrity of the test.The upper surface of the tooth block 48 is penetrated by a telescopic movable frame 413 and is slidably connected to the telescopic movable frame 413. A spring is provided on the telescopic movable frame 413 and is fixed to one end of the spring. The other end of the spring is fixedly connected to the tooth block 48. Through this arrangement, the tension of the spring can enable the rotating wheel 1 414 to clamp sleeves of different sizes. The lower surface of the telescopic movable frame 413 is rotatably connected to the rotating wheel 1 414. The upper surface of the clamping head 44 is fixedly connected to a U-shaped plate 415. The U-shaped plate 415 penetrates the tooth block 48 and is slidably connected to the tooth block 48. The upper surface of the U-shaped plate 415 is penetrated by a telescopic movable rod 416. The right surface of the telescopic movable rod 416 is rotatably connected to a rotating wheel 2 417. The lower surface of the telescopic movable rod 416 is provided with a spring and is slidably connected to the tooth block 48. One end of the spring is fixed, and the other end of the spring is fixed to the U-shaped plate 415. Through this arrangement, the elastic force of the spring can make the second runner 417 stably close to the outer arc surface of the sleeve, and cooperate with the first runner 414 to completely clamp the sleeve. Through the cooperation of the first runner 414 and the second runner 417, the upper and lower ends of the sleeve can be clamped to ensure that the sleeve is stably stuck in the tooth block 48. The upper surface of the water tank 5 is fixedly connected with a water receiving pipe 7, and an anti-slip mechanism 8 is provided at one end of the water receiving pipe 7 away from the water tank 5. The anti-slip mechanism 8 includes a water receiving head 81, which is fixedly connected to the end of the water receiving pipe 7 away from the water tank 5. The outer arc surface of the water receiving head 81 is slidably connected with a fixed block 82 in a circular array shape. The water receiving pipe 7 is fixed to the water pump, and water can be poured into the water tank 5 through the water pump and the water receiving pipe 7. The front surface of the fixing block 82 is rotatably connected to a bracket 83, and the left surface of the bracket 83 is fixedly connected to an anti-dropping claw 84. Through the cooperation between the bracket 83 and the anti-dropping claw 84, the anti-dropping claw 84 can be made to fit closely to casings of different sizes. At the same time, four groups of anti-dropping claws 84 are provided, which can clamp the upper, lower, left and right sides of the water pipe 7. An L-shaped rod 85 runs through the upper surface of the fixing block 82 and is slidably connected to the L-shaped rod 85. The L-shaped rod 85 is hinged to one end of the bracket 86, and the bracket 83 is hinged to the other end of the bracket 86. A spring is provided on the L-shaped rod 85 and is fixed to one end of the spring, and the other end of the spring is fixed to the fixing block 82. Through this arrangement, multiple groups of anti-dropping claws 84 can fix the casing, and the water head 8 The outer arc surface of 1 is fixedly connected with a connecting rod 87, which penetrates the fixed block 82 and is slidably connected with the fixed block 82. The upper surface of the connecting rod 87 is provided with a slot 88 in a linear array shape, and the inner surface of the slot 88 is slidably connected with a limit pin 89, which penetrates the fixed block 82 and is slidably connected with the fixed block 82. Through the cooperation between the connecting rod 87 and the fixed block 82, after the sleeve is fixed by the anti-detachment claw 84, it can be moved on the connecting rod 87 through the fixed block 82 to ensure that a shorter sleeve can be caught in the water receiving head 81, and the fixed block 82 is limited by the limit pin 89, which more effectively prevents the sleeve from being separated from the water receiving head 81. Through the arrangement of the actuator 2, the connector 3, the clamp 4, the water tank 5 and the tail support frame 6,The longer casing can be fixed on the clamp 4, and the extended part of the casing can be supported by the tail support frame 6. After the water is pumped into the casing through the water tank 5, the filter plate is set in the frame 1, and the water is filtered by the filter plate in the frame 1 and then flows back to the water tank 5 to complete the circulation, simulating the underground mud circulation, and achieving the effect of cooling and removing debris.

[0022] Working principle: when it is necessary to test the sleeve, one end of the sleeve is put on the connector 3, and the other end of the sleeve is stuck in the water receiving head 81. At the same time, when the sleeve is stuck in the water receiving head 81, the anti-slip claw 84 is tightly attached to the outer arc surface of the sleeve through the elastic force of the spring of the L-shaped rod 85 and the bracket 2 86. After fixing the upper, lower, left and right sides of the sleeve, the limit pin 89 is pulled upward to disengage from the slot 88 of the connecting rod 87, and the fixing block 82 is pulled to move to the right, and the anti-slip claw 84 pulls the sleeve to be stuck in the water receiving head 81. At the same time, the servo motor 41 drives the screw rod 42 to rotate, and the clamping head 44 is controlled to move on the guide rail 43. After the clamping head 44 and the protruding part of the pipe sleeve are on the same horizontal plane, the bidirectional screw rod 47 is manually rotated to make the tooth block 48 converge and separate toward the center or both sides. At the same time, the transmission belt 1 411 will be with the sleeve. The outer arc surface is in contact with each other, and at the same time, the telescopic movable frame 413 and the telescopic movable rod 416 use the elastic force and tension of the spring to limit the upper and lower surfaces of the casing with the rotating wheel 1 414 and the rotating wheel 2 417. When the water flow in the water receiving pipe 7 is small and the inner arc surface of the casing needs to be completely immersed in the simulated water in the well, by starting the small motor 412, the transmission belt 2 drives the rotating shaft 410 to rotate, and the transmission belt 1 411 will drive the casing to rotate, so that the water flow can completely simulate the water in the well and enter the casing, and the water in the water tank 5 is poured into the pipe sleeve to simulate the underground mud circulation, and at the same time achieve the effect of cooling and removing debris. At the same time, after the casing is connected to the connector 3 and the clamp 4 through the casing, the service life of the casing scraper itself and the force required for the test scraper to scrape the casing clean can be tested through the life actuator and the push-pull actuator.
