A circular composite material continuous sucker rod operating machine

Abstract

The invention relates to a round composite continuous sucker rod operation machine and method. A power roller and a prying platform are fixed to a transport vehicle, piston rods of front-back telescopic oil cylinders are connected with a movable frame, the movable frame is provided with a left-right moving oil cylinder, and the movable frame can move back and forth and leftward and rightward inside the prying platform; a cylinder body of a spiraling oil cylinder is connected to the movable frame in a hinged mode, a piston rod of the spiraling oil cylinder is connected with the upper end of a well head device assembly in a hinged mode, and the bottom end of the well head device assembly is connected with the movable frame in a hinged mode; the well head device assembly, a guide rod rack assembly and a gantry crane move back and forth and leftward and rightward along with the movable frame, so that alignment with a well head is achieved. The round composite continuous sucker rod operation machine and method have the advantages that the machine and method are suitable for ascending and descending operation of a round carbon fiber continuous sucker rod string, and the problems that a composite continuous sucker rod is great in brittleness and can be broken or cracked due to clamping easily, and holding force is hard to control are solved; the functions of well head alignment, descending of a round composite continuous sucker rod and ascending of the round composite continuous sucker rod are also achieved.

Description

technical field [0001] The invention relates to a lifting operation device for a continuous sucker rod in an oil field, in particular to a circular composite material continuous sucker rod operation machine. Background technique [0002] At present, the sucker rods used in oil fields are mainly steel sucker rods, and the steel sucker rods are mainly fixed-length sucker rods each less than 10 meters in length; there are very few continuous steel sucker rods. Fixed-length steel sucker rods are lifted and lowered by conventional operating equipment, which is slow, labor-intensive, has many safety hazards, and high operating costs; steel fixed-length sucker rods are heavy, not resistant to corrosion, and consume high energy consumption during work. The steel continuous sucker rod is lifted and lowered by special equipment, the operation speed is fast, the labor intensity of the workers is low, and there are few safety hazards, but the steel continuous sucker rod is heavy and not...
