An integrated sucker rod automatic slip and operation process

Abstract

The invention relates to the technical field of a sucker rod auxiliary device for well workover operations and an operation process, in particular to an integrated sucker rod automatic slip and an operation process. The technical solution is: including the sucker rod clamping module and the make-up and breakout module, the sucker rod clamping module and the make-up and breakout module are connected by a V-shaped block, the make-up and breakout module is integrated into the sucker rod clamping module, and the upper and lower The shackle pliers can precisely hold the wrench side of the sucker rod; the quick-change slip core and the quick-change locking block are installed inside the sucker rod clamping module, which can clamp the flange surface of the sucker rod of different sizes; the quick-change clamp The tile core and the quick-change locking block form a complete arc surface, which can limit the extraction of the sucker rod and improve the safety of the operation; the clamping and opening state of the sucker rod module is completed by the stepping motor to drive the split screw nut pair, The movement of make-up and breakout is driven by linear guide. Beneficial effects: the working efficiency of well workover can be improved, the labor intensity of workers can be reduced, and the automation of sucker rod clamping and making-up and breaking-out actions can be realized.

Description

technical field [0001] The invention relates to the technical field of a sucker rod auxiliary device for well workover operations and an operation process, in particular to an integrated sucker rod automatic slip and an operation process. Background technique [0002] Workover operations are the most common form in oilfields, which can be divided into minor repair operations and major repair operations. Minor repair operations mainly transport pipe strings through lifting and lowering actions to complete the operation tasks, mainly including pump inspection, process change, sand washing and other operations. At present, the characteristic of the mainstream sucker rod operation process is that it is completed by both machinery and manpower. The lifting of the sucker rod is mainly driven by the hook, and at least two elevators are circulated between the hook and the center of the wellhead. One of the two elevators is used as an elevator, and the other is used as a slip. The t...

AI Technical Summary

Problems solved by technology

In the whole process of lifting and lowering the sucker rod, there are problems such as a large amount of manpower, high labor intensity, poor open-air construction environment in the field, and high safety risks.
