Description

Technical Field

[0001] The present invention relates to the technical field of oil and gas exploitation, and in particular to a continuous oil pipe working device and a working method. Background Art

[0002] With the development of society, industries such as mining and quarrying occupy an important position in the national economy. In these industries, coiled tubing technology has been widely used. Coiled tubing is a kind of tubing that is continuously lowered into or pulled out of the well by coiled tubing. It has the characteristics of being bendable and able to be continuously lowered into the well. Coiled tubing plays a key role in oil and gas extraction and downhole operations. It can realize efficient fluid transportation, downhole tool lowering and other operations, greatly improving operation efficiency and safety.

[0003] During the use of coiled tubing, releasing and reeling are two important links. When releasing the tubing, the coiled tubing needs to be released smoothly from the reel to ensure that the tubing is not damaged during underground operations; when reeling the tubing, the used coiled tubing needs to be rewound on the reel for the next use. The smooth progress of these two links is crucial to ensure the service life and operation effect of the coiled tubing.

[0004] However, there are some problems with the existing coiled tubing equipment when in use. On the one hand, it is impossible to ensure that the coiled tubing is evenly wound on the drum. This may cause uneven accumulation of the tubing on the drum, affecting the smoothness of the next release, and may even cause damage to the tubing. On the other hand, when the coiled tubing is recovered, there will be mud or impurities on its outer wall, and these mud and impurities are directly wound on the drum without effective cleaning. This will not only pollute the drum, but also accelerate the wear of the tubing, reduce its service life, and increase the maintenance cost of the equipment. Summary of the invention

[0019] First, the coiled tubing passes through the tube collection component 6 and the cleaning component 7, wherein the tube collection component 6 provides the power for the movement of the coiled tubing, and the cleaning component 7 can clean the impurities on the outer wall of the coiled tubing to prevent the sand or impurities on the outer wall of the tubing from contaminating the drum 2 or accelerating the wear of the tubing and reducing its service life. When the tube collection work is performed, the first driving motor 402 in the driving component 4 drives the drum 2 to rotate. When the drum 2 rotates, it drives the rotating wheel 405 to rotate, and the inner half tooth groove 410 and the outer half tooth groove 411 inside the rotating wheel 405 also rotate accordingly. When the first gear 409 corresponds to the inner half tooth groove 410, the first gear 409 rotates clockwise. When the first gear 40 When the first gear 409 corresponds to the outer half tooth groove 411, the first gear 409 rotates counterclockwise. Since the first gear 409 is fixed on the rotating shaft 301, the rotating shaft 301 will rotate clockwise for a while and then automatically switch to counterclockwise rotation. The rotating shaft 301 is provided with a thread groove 302. The moving block 304 cooperates with the screw hole 306 and the sliding hole 305 so that when the rotating shaft 301 rotates, it will drive the moving block 304 to move along the rotating shaft 301 and the sliding rod 303. Then the continuous oil pipe passes through the first ear plate 307. The movement of the moving block 304 will change the winding position of the continuous oil pipe on the drum 2, and then cooperate with the rotation of the drum 2 itself, so that the continuous oil pipe is evenly wound on the drum 2.

[0020] The left and right ends of the outer wall of the drum 2 are fixedly connected with a support shaft 201. An oil passage 202 is opened inside the drum 2. The oil passage 202 runs through the support shaft 201 on the right side of the drum 2. A first bearing 203 is fixedly installed at the oil inlet end of the oil passage 202. The first bearing 203 is located inside the right support shaft 201.

[0021] When in use, the support shaft 201 is used to support the drum 2 so that it can rotate stably on the first support frame 1, and then the external oil pipe is installed in the inner ring of the first bearing 203, and then the continuous oil pipe is connected to the oil outlet end of the oil channel 202. During use, the continuous oil pipe can be connected to the external oil pipe through the oil channel 202. At the same time, the function of the first bearing 203 is that when the drum 2 rotates, the external oil pipe will not rotate with the drum 2.

[0022] The driving assembly 4 also includes a second bearing 401 and a first driving motor 402. Two second bearings 401 are fixed on the top of the first support frame 1. Two support shafts 201 are fixedly installed in the inner rings of the second bearings 401. The first driving motor 402 is fixedly installed on the top of the first support frame 1, and the left support shaft 201 is fixedly installed on the output end of the first driving motor 402.

[0023] When in use, after the first drive motor 402 is started, its output end drives the left support shaft 201 to rotate, and the support shaft 201 rotates stably on the first support frame 1 through the second bearing 401, thereby driving the drum 2 to rotate, ensuring smooth tube collection and release operations.

[0024] The driving assembly 4 also includes a first outer gear ring 403, a second outer gear ring 406 and a third support frame 404. The first outer gear ring 403 is fixedly connected to the outer wall of the right support shaft 201, the second outer gear ring 406 is fixedly connected to the outer wall of the rotating wheel 405 and meshes with the first outer gear ring 403. The third support frame 404 is located on the right side of the first support frame 1, and the rotating wheel 405 is movably installed on the top of the third support frame 404.

[0025] When the drum 2 rotates, the first outer gear ring 403 on the right support shaft 201 cooperates with the second outer gear ring 406 to drive the rotating wheel 405 to rotate; the third support frame 404 can support the rotating wheel 405 to prevent the rotating wheel 405 from shaking during rotation.

[0026] The tube collecting assembly 6 includes a second ear plate 601, a mounting frame 602, a cam 603, a second drive motor 604 and a second gear 605. The second ear plate 601 has two fixed connections on the top of the second support frame 5. The mounting frame 602 is fixedly connected to the top of the drum 2 and is located between the two second ear plates 601. The cam 603 has multiple symmetrically mounted inside the mounting frame 602. The second drive motor 604 is fixedly mounted on the bottom of the mounting frame 602. The output end of the second drive motor 604 is fixedly mounted on the bottom of the cam 603. The second gear 605 has two fixed connections on the tops of two opposite cams 603. The two second gears 605 are meshed with each other.

[0027] When in use, after the second driving motor 604 is started, it drives the cam 603 to rotate, and then drives the second gear 605 on the top to rotate. Because the two second gears 605 are meshed with each other, it can ensure that the two opposite cams 603 rotate at the same time. While multiple cams 603 clamp the coiled tubing, when the two cams 603 at the front end rotate, the coiled tubing can be driven to move, thereby realizing the tube collection operation.

[0028] The cleaning assembly 7 includes a water pump 701, a water injection pipe 702, an annular scraper 703, a connecting rod 704, an annular water outlet pipe 705, a nozzle 706 and a flange 707. The water pump 701 is fixedly installed inside the water tank 8, the water injection pipe 702 is fixedly installed at the water outlet end of the water pump 701, the flange 707 is fixedly connected to the outer wall of the second ear plate 601 at the front end, the annular scraper 703 is fixedly installed at the front end of the flange 707 by bolts, the connecting rod 704 has multiple fixed connections at the front end of the annular scraper 703, the annular water outlet pipe 705 is fixedly connected to the front end of the connecting rod 704, the nozzle 706 has multiple movably connected to the front end of the annular water outlet pipe 705, and the water outlet end of the water injection pipe 702 is fixedly connected to the annular water outlet pipe 705.

[0029] During the coiled tubing recovery process, the water pump 701 delivers water from the water tank 8 to the annular water outlet pipe 705 through the water injection pipe 702, and then the water is sprayed out by the nozzle 706 to wash the outer wall of the coiled tubing. At the same time, because the coiled tubing is moving, the dirt on the outer wall will be scraped off by the annular scraper 703 when passing through the annular scraper 703, which can effectively clean the sand or impurities on the outer wall of the coiled tubing, extend the service life of the coiled tubing, and keep the equipment clean.

[0030] A collecting box 801 is slidably mounted inside the water tank 8 , a filtering hole 802 is provided at the bottom of the collecting box 801 , and a buckle groove 803 is provided at the front end of the collecting box 801 .

[0031] The dirt and sand scraped and washed off the coiled tubing fall into the collection box 801, and the water is filtered through the filter hole 802 and returns to the water tank 8 for recycling. After use, the collection box 801 is taken out through the buckle groove 803 to clean the dirt and sand inside.

[0032] A working method of a coiled tubing working device, using the coiled tubing working device, comprises the following steps: S1, pass the coiled tubing through the tube receiving assembly 6 and the cleaning assembly 7, then pass through the first ear plate 307 inside the moving block 304 in the correction assembly 3, and finally connect to the drum 2; S2, when collecting the pipe, the pipe collecting component 6 performs the pipe collecting work, and the cleaning component 7 cleans the dirt on the outer wall of the connecting oil pipe while collecting the pipe; S3, turning on the driving assembly 4, and driving the drum 2 to rotate through the first driving motor 402 in the driving assembly 4; S4. When the drum 2 rotates, the rotating wheel 405 is driven to rotate through the drum 2, and the inner half tooth groove 410 and the outer half tooth groove 411 inside the rotating wheel 405 rotate together with the rotating wheel 405. When the first gear 409 of the driving component 4 corresponds to the inner half tooth groove 410, the first gear 409 is driven to rotate clockwise. When the first gear 409 of the driving component 4 corresponds to the outer half tooth groove 411, the first gear 409 is driven to rotate counterclockwise. The clockwise / reverse alternating rotation of the first gear 409 drives the clockwise / reverse alternating rotation of the rotating shaft 301, and under the cooperation of the rotating shaft 301 and the moving block 304, the rotating shaft 301 drives the moving block 304 to reciprocate and translate, so that the coiled tubing can be evenly wound on the drum 2.

[0033] Working principle: First, pass the connecting oil pipe through the two second ear plates 601, then through the first ear plate 307, and finally connect to the drum 2.

[0034] When the tube is collected, the second driving motor 604 is started, driving the cam 603 to rotate, and then driving the second gear 605 on the top to rotate. Because the two second gears 605 are meshed with each other, it can be ensured that the two opposite cams 603 rotate at the same time. While the multiple cams 603 clamp the coiled tubing, the coiled tubing is driven to move toward the drum 2 to achieve the tube collection operation.

[0035] Then, during the recovery process of the coiled tubing, the water pump 701 transports the water in the water tank 8 to the annular water outlet pipe 705 through the water injection pipe 702, and then the water is sprayed out by the nozzle 706 to wash the outer wall of the coiled tubing. At the same time, because the coiled tubing is moving, the dirt on the outer wall will be scraped off by the annular scraper 703 when passing through the annular scraper 703.

[0036] Next, the first drive motor 402 starts to work, and the output end of the first drive motor 402 drives the left support shaft 201 to rotate. The support shaft 201 rotates stably on the first support frame 1 through the second bearing 401, thereby driving the drum 2 to rotate and winding the connecting oil pipe around the drum 2.

[0037] While the drum 2 rotates, the first outer tooth ring 403 on the right support shaft 201 drives the rotating wheel 405 to rotate, and the inner half tooth groove 410 and the outer half tooth groove 411 inside the rotating wheel 405 rotate together with the rotating wheel 405. When the first gear 409 corresponds to the inner half tooth groove 410, the first gear 409 rotates clockwise; when the first gear 409 corresponds to the outer half tooth groove 411, the first gear 409 rotates counterclockwise. Since the first gear 409 is fixed on the rotating shaft 301, the rotating shaft 301 will rotate clockwise for a while and then automatically switch to counterclockwise rotation. The rotation of the rotating shaft 301 drives the moving block 304 to move along the rotating shaft 301 and the sliding rod 303. The movement of the moving block 304 changes the winding position of the continuous oil pipe on the drum 2, and combined with the rotation of the drum 2 itself, the continuous oil pipe can be evenly wound on the drum 2.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein.
