Horizontal moving device for perforating gun for oil-gas-well

Abstract

The invention relates to a horizontal moving device for a perforating gun for an oil-gas-well. The horizontal moving device is characterized by comprising a device base, servo motors, two screw rods, two fixed blocks, a moving support, a clamping rod, springs, travel switches, a clamp and a PLC, wherein crossbeams at the top of the device base are erected above the mouth of the well, the two screw rods are fixed on the crossbeams in parallel, and the plane where the screw rods are located is parallel to the ground plane; the two fixed blocks are arranged at the two ends of each screw rod and are perpendicular to the screw rods, a rectangular frame is formed by the fixed blocks and the crossbeams, and the travel switches are arranged on the fixed blocks; each servo motor is arranged at one end of the corresponding screw rod, the moving support is connected with the screw rods through threads, and the moving support moves back and forth as the screw rods rotate; the springs are fixed on the face, facing one fixed block, of the moving support, and the positions of the springs correspond to those of the travel switches; the upper end of the clamping rod is fixed to the moving support, and the lower end of the clamping rod is connected with the clamp used for clamping the perforating gun.

Description

technical field [0001] The invention relates to the field of on-site production and processing in the petroleum industry, in particular to a horizontal transfer device for perforating guns used in oil and gas wells. Background technique [0002] After the oil production well is drilled, the interconnected seamless steel pipes are lowered into the wellbore to form a casing, and then cement is injected between the well wall and the casing for cementing. When the cementing is completed, the oil and gas layers and the well wall are also sealed off. When the oil production process is in progress, the perforating gun loaded with perforating bullets must be lowered along the casing to the oil-bearing layer, perforate around the casing, break down the casing and cement layer, and shoot into the oil layer. The crude oil can flow into the casing through the injected hole, which is the perforating operation. [0003] Commonly used perforating guns have an outer diameter of Φ102mm and...

AI Technical Summary

Problems solved by technology

At present, after the machining of the perforating gun is completed, the operator usually moves it to the place by hand, which not only increases the labor intensity and reduces the work efficiency, but also easily causes safety accidents
