An integrated guide type vertical workover catwalk for wellhead positioning and its 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 oil drilling and workover mechanical equipment, in particular to a wellhead positioning integrated guided vertical workover catwalk and a use method.Background technique[0002]The catwalk is widely used in the lifting and lowering operations of petroleum workovers, and most of the lifting and lowering of tubing and sucker rods are completed through the catwalk. Most of the existing catwalks are lift-type. The tubing or sucker rod is lifted to the wellhead, and the elevator is manually connected to the tubing or sucker rod, and then discharged to the top of the wellhead. The elevator equipment is heavy and frequently and boring. , The labor intensity is high. Existing catwalks require more equipment to be replaced for the lifting and lowering operations of oil pipes and sucker rods, and the replacement process is complicated.Summary of the invention[0003]The purpose of the present invention is to provide a wellhead p...

Problems solved by technology

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. , labor-intensive

The existing catwalk needs to replace a lot of equipment for lifting and lowering oil pipes and sucker rods, and the replacement process is cumbersome
