[0002] During the production process of injection and production wells in oil fields, the repair and replacement of Christmas tree valves is a frequent maintenance task. These operations usually require a lot of manpower and time, especially when removing and installing valves. The labor intensity is high, the production downtime is long, and the operation is time-consuming. These problems are particularly prominent when replacing the production valves and main valves of the Christmas tree. Due to the misalignment, tilt, and close distance between the connecting process pipelines and the Christmas tree, the removal and installation are further difficult.

[0026] like Figure 1 As shown, the utility model provides a multifunctional injection and production equipment maintenance auxiliary device, comprising: a ratchet wrench 1 and a main body connecting pipe 2;

[0027] The main connecting tube 2 is a hollow cylindrical structure, the inner wall of the main connecting tube 2 is provided with a thread, and a ratchet wrench 1 is sleeved at the center of the main connecting tube 2. The ratchet wrench 1 limits the axial position of the main connecting tube 2 through two symmetrical limit caps 3. The center of the main connecting tube 2 is provided with gear teeth matching the ratchet wrench 1. The ratchet wrench 1 is rotatably connected to the main connecting tube 2. By rotating the ratchet wrench 1, the main connecting tube 2 can be rotated. The ratchet wrench 1 is the core component of the entire device and is responsible for realizing the rotation function. By rotating the ratchet wrench 1, the main connecting tube 2 can be driven to rotate;

[0028] The lower end of the ratchet wrench 1 is provided with an anti-slip handle 8. The anti-slip handle 8 is a hollow cylindrical structure. The anti-slip handle 8 is sleeved on the lower end of the ratchet wrench 1. The anti-slip handle 8 is made of rubber material. The anti-slip handle 8 provides a good grip and prevents slipping during operation.

[0029] The two spiral adjustment columns 5 are provided at both ends of the main connecting tube 2. The spiral adjustment columns 5 are embedded in the main connecting tube 2. The two spiral adjustment columns 5 are symmetrically distributed. The outer wall of the spiral adjustment column 5 is provided with a thread matching the inner wall of the main connecting tube 2 to ensure that the two can be rotatably connected. By rotating the spiral adjustment column 5, the overall length of the device can be adjusted to meet the needs of different working scenarios.

[0030] The spiral adjustment column 5 is provided with a fixing device, which includes: a fixed snap ring 4, a rotating snap ring 6 and a fixing bolt 7. The fixed snap ring 4 and the rotating snap ring 6 are both semi-circular ring structures and can be combined into a complete circular ring. The fixed snap ring 4 is provided with a through hole matching the fixing bolt 7 for locking connection. The fixed snap ring 4 and the spiral adjustment column 5 are made as one body and are connected to the rotating snap ring 6 through a rotating shaft so that the two can rotate relative to each other. The fixing bolt 7 is used to lock the fixed snap ring 4 and the rotating snap ring 6 tightly together to ensure stability during use.

[0031] The following is a detailed introduction to the actual working scenario of a multifunctional injection and production equipment maintenance auxiliary device.

[0032] In actual work, the multifunctional injection and production equipment maintenance auxiliary device is used to assist in replacing valves in oil production wells and water injection wells. The working process includes the following steps:

[0033] Step S1: Adjust the length of the device. According to the actual situation of the injection and production well, the device is adjusted to a suitable length by rotating the spiral adjustment column 5 and the main connecting pipe 2. This ensures that the device can flexibly adapt to different working scenarios and equipment specifications.

[0034] Step S2: Prepare the fixing device. Open the fixing bolts 7 on the fixing devices at both ends to prepare for the subsequent fixing operation. Turn the ratchet wrench 1 to the appropriate position, and place the fixing rings 4 on both sides tightly against the connecting process pipeline. Turn the rotating ring 6 so that the fixing device is completely covered on the connecting process pipeline. Lock the two fixing devices with the fixing bolts 7 to ensure the stability of the device during use.

[0035] Step S3: Loosen the valve clamp. After the fixture is locked, the technician can begin to loosen the valve clamp. After loosening the valve clamp, the technician continues to turn the ratchet wrench 1 to move the two spiral adjustment columns 5 outward. This action will open the connecting process pipeline, allowing the valve to be easily removed for replacement or maintenance.

[0036] Step S4: Replace or repair the valve. After the connecting process pipeline is stretched, the technician can easily remove the old valve and perform replacement or repair operations. After the new valve is replaced and installed, the technician rotates the ratchet wrench 1 in the opposite direction to gradually restore the connecting process pipeline to its original position and dock it with the new valve. After ensuring that the valve is tightly connected to the connecting process pipeline, the valve clamp is installed.

[0037] Step S5: Remove the device. After installation is completed, loosen the fixing bolt 7 to release the locking state of the fixing device, remove the multifunctional injection and production equipment maintenance auxiliary device, and complete the entire replacement or maintenance process.

[0038] It can be understood that the above-mentioned embodiments mentioned in the present invention can be combined with each other to form combined embodiments without violating the principle logic. Due to space limitations, the present invention will not elaborate on them.

[0039] Those skilled in the art will understand that in the above-mentioned method of the specific implementation method, the writing order of each step does not mean a strict execution order and does not constitute any limitation on the implementation process. The specific execution order of each step should be determined by its function and possible internal logic.
