Quick loading and unloading method of water tap in workover operation and combined manipulator

Abstract

The invention provides a method for fast loading and unloading of a workover faucet and a combined manipulator, and relates to the technical field of well workover operations. The method for quickly loading and unloading a workover faucet provided by the invention includes: disassembly steps: the second pushing manipulator and the hook of a traveling car Drive the lower end of the swivel kelly assembly into place, the elevator is released from the swivel kelly assembly, and the first pushing manipulator drives the upper end of the swivel kelly assembly into place; installation steps: the first pushing manipulator drives The upper end of the swivel kelly assembly is aligned with the elevator, and the upper end of the swivel kelly assembly is connected to the elevator. The second pushing manipulator drives the upper end of the swivel kelly assembly with the cooperation of the traveling block hook. The lower end moves to the wellhead station. The quick loading and unloading method of the swivel in the workover operation provided by the present invention greatly simplifies the disassembly and assembly steps of the swivel kelly assembly, effectively improves the coupling efficiency, reduces the operating intensity of workers, eliminates operational risks, and realizes full coverage of the operation automation process.

Description

technical field [0001] The invention relates to the technical field of well workover operations, in particular to a quick loading and unloading method of a water tap for well workover operations and a combined manipulator. Background technique [0002] The overhaul operation automation equipment realizes the automatic processing of the pipe string during the tripping process of the workover operation. Specifically, it includes functions such as lifting and clamping of the pipe string, automatic placement of the pipe string on the drill floor and the second-floor platform, etc. The tripping operation can be completed in the driller's operating room by only one person. Among them, the suspension of the pipe string is realized by the hydraulic flip elevator. The hydraulic flip elevator is heavy, and the installation and disassembly are relatively complicated. However, during the overhaul operation, the faucet kelly is often used to connect the drilling tool for grinding, drilli...

Problems solved by technology

[0003] When the faucet is unhooked and continuously rotated, the above processes need to be cyclically operated, but the space on the rig floor is small, requiring many personnel, and there are certain safety hazards, and the operation process is frequently switched, the process is cumbersome, time-consuming and laborious, and it is impossible to achieve full coverage of the operation automation process. , The problem of quickly removing and hanging the faucet needs to be solved urgently
