Description

Technical Field

[0001] This invention belongs to the field of automated well workover technology in the oil production engineering of the petroleum industry, specifically involving a pressurized automated tubing auxiliary lifting device and lifting method. Background Technology

[0002] Currently, in my country's oil well workover industry, 80% of pressurized well workover operations involve tubing pull-in / pull-out. During this process, due to the weight of the tubing, it may fall into the coupling after uncoupling, causing sticking. Operators must manually straighten the tubing using tools before using a lifting clamp to pull it out. This poses a significant safety hazard. If personnel are present at the wellhead during the pull-in process, any abnormality may occur, making it difficult for operators to react or respond promptly, potentially leading to accidents such as tubing falling and personnel injuries.

[0003] Currently, during automated tubing string pulling operations, no one is at the wellhead; instead, a robotic arm is used to replace manual labor. Due to the limitations of the robotic arm's structure, if sticking occurs, it is difficult to center the tubing string when pulling it out. Forcibly pulling the tubing out can cause it to bounce, posing a risk of the tubing falling off. Summary of the Invention

[0004] To address the aforementioned issues, this invention provides an automated pressurized tubing lifting device and method. In field use, it can straighten the tubing string, resolve the tubing eccentricity problem during lifting, reduce the risk of forced tubing pull-out and bouncing caused by hook-and-loop fastening, significantly reduce the difficulty of the robotic arm in retrieving the tubing, and also reduce the risk of the tubing string falling during lifting.

[0005] This technology is the first of its kind in the industry. Compared with the traditional manual pipe-lifting technology, this method transforms the traditional manual operation into an automated operation, and can monitor the operation status in real time, avoiding pipe drop accidents and greatly improving operation safety and efficiency.
