Wellhead positioned integrated guide vertical well repair catwalk and application method

Abstract

The invention relates to a wellhead positioned integrated guide vertical well repair catwalk and an application method. According to the technical scheme of the wellhead positioned integrated guide vertical well repair catwalk, the two sides of a base are connected with a plurality of hydraulic supporting legs and a plurality of ground anchors and used for supporting the vertical catwalk; a lifting arm cylinder is hinged to a lifting arm; a guide rod is hinged to a guide rod cylinder; a guide rod diagonal brace is hinged to the guide rod; the lifting arm cylinder can drive the lifting arm to be turned over from the horizontal state to the vertical state; the guide rod cylinder can drive the guide rod to be turned over from the horizontal state to the vertical state; the guide rod diagonalbrace can make the guide rod maintain the vertical state; and the guide rod diagonal brace can be taken down in a transportation state for independent storage. The wellhead positioned integrated guidevertical well repair catwalk has the beneficial effects that an oil pipe or a sucker rod is turned over by 90 degrees and conveyed to above a wellhead instead of an original lifting mode; the intermediate link that the oil pipe or the sucker rod in an original lifting catwalk is conveyed to the wellhead and is in an inclined state is omitted; and the oil pipe or the sucker rod is directly conveyed from the horizontal state to the vertical state, and the working efficiency in the catwalk is improved.

Description

technical field [0001] The invention relates to the technical field of petroleum drilling and workover mechanical equipment, in particular to an integrated guide type vertical operation and workover catwalk for wellhead positioning and a use method thereof. Background technique [0002] Catwalks are widely used in lifting and lowering operations of petroleum workovers, and the lifting and lowering of tubing and sucker rods are mostly done through catwalks. Most of the existing catwalks are lifting type. The tubing or sucker rod is lifted to the wellhead, and the elevator is connected to the tubing or sucker rod manually, and then discharged to the top of the wellhead. The weight of the elevator equipment is heavy, and the action is frequent and boring. , The labor intensity is high. For the existing catwalk, for lifting and lowering oil pipes and sucker rods, a lot of equipment needs to be replaced, and the replacement process is cumbersome. Contents of the invention [...
