[0024] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0025] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0026] See also Figures 1 to 5 The embodiment of the utility model provides a composite unblocking injection device, which comprises: a base frame 1, a mounting frame 11 and a liquid storage tank 2 are provided on the base frame 1, a rotatably connected winding roller 12 is mounted in the mounting frame 11, and an injection pipe 3 is wound around the winding roller 12.

[0027] In the embodiments of the present invention, please refer to Figures 1 to 5 A processing box 4 is provided on the base frame 1, and a cleaning assembly 5 for cleaning the injection pipe 3 is provided inside the processing box 4. The cleaning assembly 5 includes a fixed frame 51, which is arranged at the inner bottom of the processing box 4. A rotating cylinder 52 connected in rotation is provided inside the fixed frame 51, and a plurality of cleaning strips 521 distributed in an annular manner are provided inside the rotating cylinder 52; guide cylinders 53 are provided on both sides of the rotating cylinder 52 at the top of the fixed frame 51, and a rotating motor 54 is provided on one side of the top of the fixed frame 51, and a driving wheel 541 is provided at the output end of the rotating motor 54, and the outer wall of the driving wheel 541 is against the outer wall of the rotating cylinder 52, a partition 41 is provided inside the processing box 4, and cleaning liquid is added to the space inside the processing box 4 opposite to the cleaning assembly 5, a support frame 42 is provided on the top of the partition 41, and a scraper cylinder 43 is provided inside the support frame 42.

[0028] It should be noted that: after the injection of the unblocking agent is completed, when the injection pipe 3 is rolled up, the scraper drum 43 located on the outside will first perform preliminary scraping and cleaning of the sludge on the outer wall of the movable injection pipe 3. When the injection pipe 3 after preliminary cleaning moves to the inside of the rotating drum 52, the working rotating motor 54 drives the driving wheel 541 to rotate. The driving wheel 541 can drive the rotating drum 52 to rotate by abutting against the outer wall of the rotating drum 52, and then drive the cleaning strip 521 inside the rotating drum 52 to rotate synchronously. In this process, as the injection pipe 3 moves, the outside of the injection pipe 3 can be spirally scrubbed and cleaned, so that the outside of the recycled injection pipe 3 can be made cleaner. The outer wall of the rolled-up injection pipe 3 can be made cleaner by a multi-stage automatic cleaning method combined with the scraper drum 43.

[0029] By providing a partition 41 inside the treatment box 4 and the space corresponding to the scraper 43, the sludge scraped off by the scraper 43 can be collected, so that the staff can carry out centralized cleaning later. By adding cleaning liquid in the space relative to the cleaning component 5, the brushing effect of the cleaning strip 521 on the injection pipe 3 can be improved.

[0030] In the embodiments of the present invention, please refer to Figures 1 to 5 A motor for driving the winding roller 12 is provided on one side wall of the mounting frame 11, a reciprocating screw rod 13 is rotatably connected to the top of the mounting frame 11, and the output end of the motor is connected to the reciprocating screw rod 13 through a chain and a sprocket transmission, a threaded moving block 14 is sleeved on the reciprocating screw rod 13, the interior of the moving block 14 is slidably connected to the outer wall of the support rod in the mounting frame 11, and a guide block 15 is provided at the bottom of the moving block 14, the inner wall of the guide block 15 is slidably connected to the outer wall of the injection pipe 3, and the injection pipe 3 is inserted into the scraper cylinder 43, the rotating cylinder 52 and the guide cylinder 53.

[0031] It should be noted that: through the setting of the reciprocating screw 13, during use, when the motor drives the winding roller 12 to rotate, the reciprocating screw 13 can be synchronously driven to rotate through the transmission of the chain and the sprocket. At this time, the rotating reciprocating screw 13 will drive the guide block 15 and the injection tube 3 to move back and forth synchronously through the threaded structure of the moving block 14, so that the later placement or winding of the injection tube 3 can be more uniform, thereby reducing the phenomenon of entanglement and knotting of the injection tube 3.

[0032] In the embodiments of the present invention, please refer to Figures 1 to 5 One end of the injection pipe 3 is connected to the interior of the winding roller 12, and a connected pump body 21 is provided on the top of the liquid storage tank 2. A transfer pipe 22 is provided at the output end of the pump body 21, and the end of the transfer pipe 22 is connected to one end of the winding roller 12 through a rotating joint.

[0033] It should be noted that: by connecting the end of the transfer tube 22 and the end of the winding roller 12 with a rotating structure, when the winding roller 12 rotates, it can be avoided that it drives the transfer tube 22 to rotate synchronously, causing the transfer tube 22 to be entangled, so that the transfer tube 22 can stably introduce the unblocking agent from the pump body 21 into the winding roller 12, and flow it into the injection pipe 3 through the winding roller 12, so that the injection pipe 3 can stably discharge the unblocking agent to unblock the oil well.

[0034] The working principle of the composite plugging removal injection device provided by the utility model is as follows;

[0035] When using the device, the device can be first moved to the desired position, and then the motor can be controlled to drive the winding roller 12 to rotate to pay out the line, so as to extend the injection pipe 3 into the oil well, and then the pump body 21 can be controlled to work to send the unblocking agent in the liquid storage tank 2 into the injection pipe 3 through the transfer pipe 22, and then it can be transported to the blocked position through the injection pipe 3 to perform unblocking operations;

[0036] When the use of the device is completed, the pump body 21 can be stopped first, and then the motor can be controlled to drive the winding roller 12 to rotate in the opposite direction. During the process of the winding roller 12 rotating in the opposite direction to rewind the injection tube 3, the reciprocating screw rod 13 can be driven to rotate by the chain and the sprocket. The rotating reciprocating screw rod 13 will drive the moving block 14 on the outer wall to reciprocate on the support rod in the mounting frame 11. The reciprocating moving block 14 will drive the injection tube 3 to reciprocate synchronously through the guide block 15, so that the winding roller 12 can rewind the injection tube 3 more evenly.

[0037] In the process of winding the injection pipe 3, the external injection pipe 3 can first move inside the scraper 43, and because the inner wall of the scraper 43 abuts against the outer wall of the injection pipe 3, the end of the scraper 43 can scrape the outer wall of the injection pipe 3 while the injection pipe 3 moves, thereby preliminarily cleaning the sludge on the outer wall of the injection pipe 3;

[0038] When the injection pipe 3 that has been cleaned of sludge moves to the rotating drum 52 of the cleaning component 5, the rotating motor 54 working in this process can drive the driving wheel 541 to rotate. The rotating driving wheel 541 will drive the rotating drum 52 to rotate in the fixed frame 51 by abutting against the outer wall of the rotating drum 52, so that the cleaning strip 521 inside the rotating drum 52 can perform secondary scraping and brushing cleaning on the outer wall of the injection pipe 3 in the processing box 4. By adding cleaning liquid in the processing box 4, the injection pipe 3 can be cleaned more thoroughly during the scraping process of the cleaning strip 521. Therefore, the rolled injection pipe 3 can be made cleaner through a multi-stage automatic cleaning method.

[0039] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.

[0040] The above are only embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
