Double-flap jacking type sucker rod workover operation power slip and operation process

Abstract

The invention relates to the technical field of workover operation sucker rod auxiliary devices and operation processes, in particular to a double-flap jacking type sucker rod workover operation powerslip and an operation process. According to the technical scheme, hydraulic cylinders, connecting rods and sucker rod clamping units are sequentially installed on a power slip box body from bottom totop, the two sets of hydraulic cylinders are located at the front-back symmetrical positions in the slip box body correspondingly, the upper ends of pistons of the hydraulic cylinders are connected to the bottoms of the two sets of sucker rod clamping units through the two sets of connecting rods correspondingly, guide rails are arranged on the outer walls of the sucker rod clamping units, the inner wall of the power slip box body is of a wide-end-up structure, guide rail grooves are formed in the inner wall of the power slip box body, the sucker rod clamping units move up and down along theguide rail grooves in the inner wall of the power slip box body, a cylindrical groove is formed after the sucker rod clamping units are combined, and a sucker rod is clamped when the two sucker rod clamping units move downwards. The device is applied together with an elevator for petroleum workover, the efficiency of workover operation can be improved, and then automation of the workover operationis achieved.

Description

technical field [0001] The invention relates to the technical field of a sucker rod auxiliary device for well workover operation and an operation process, in particular to a double-lobe jacking type sucker rod workover power slip and an operation process. Background technique [0002] The traditional workover operation method is mainly manual. After the sucker rod needs to be manually straightened, the sucker rod slips are clamped, rotated and locked to support the entire operation, and as the sucker rod is lifted by the workover hook, The entire sucker rod operation has been completed, but there are problems such as high labor occupation, high labor intensity, poor open-air construction environment in the field, and high safety risks, especially the sucker rod operation is more prominent. The clamping requirements of the sucker rod are very high, the flange surface of the flange of the clamped sucker rod must become a complete flange surface when tightening, and the two hal...
