Elevator transfer method for mechanized workover operation

Abstract

The invention discloses a mechanical workover treatment elevator transportation method. An elevator transportation mechanism is located on one side of a well mouth axis, two transportation hands are symmetrical about the well mouth axis, and the transportation hands are used for hooking suspension rings of an intelligent elevator to drive the intelligent elevator to rotate along with a transportation frame, so that elevator transportation is achieved. In the transportation process, the transportation hands can hook the elevator all the time, and therefore elevator falling accidents are completely eradicated. The mechanical workover treatment elevator transportation mechanism is composed of a hydraulic motor, a rotary mandrel, the transportation frame, hinge shafts and transportation hand bodies, wherein the hinge shafts and the transportation hand bodies form the transportation hands used for transporting the intelligent elevator. According to the mechanical workover treatment elevator transportation method, mechanical elevator transportation during workover treatment can be achieved, the space of the well mouth axis is not occupied in the transportation process, the mechanical degree of the workover treatment is improved, the worker labor intensity is lowered, and meanwhile workover treatment efficiency is not affected.

Description

technical field [0001] The invention relates to oil industry workover operation technology, in particular to a mechanized workover operation elevator transfer method. Background technique [0002] In traditional workover operations, elevator transfer is the link that consumes the most physical strength of workers. When elevators are switched, they rely on workers to carry them, which is labor-intensive and the working environment is harsh. [0003] Patent ZL201320137833.3 Mechanized Workover Operation Elevator Transfer Device In the process of transferring elevators, the left and right arms alternately take over the elevators. Although the mechanized operation is realized, the process of alternately switching the elevators between the left and right arms has always occupied the axis of the wellhead. , the process is complicated, and at the same time, the hook is in a waiting state when transferring the elevator, which reduces the workover efficiency. [0004] In view of the...
