Comprehensive wellhead operation device for workover operations

Abstract

The invention discloses a comprehensive well mouth operating device for workover treatment. The comprehensive well mouth operating device comprises a well mouth pneumatic slip, a hydraulic clamp pneumatic throttle, a valve elevator, a folding type well mouth operating platform, an oil tube bed hydraulic lifting oil tube hydraulic conveying device or oil tube hydraulic lifting device and a magnetic screw protector. The folding type well mouth operating platform is installed on a well mouth blowout preventer with the well mouth facing a workover frame, the hydraulic clamp pneumatic throttle is arranged on the folding type well mouth operating platform, the well mouth pneumatic slip is arranged on the well mouth, the special valve elevator is arranged on an ascending or descending oil tube, the oil tube bed hydraulic lifting oil tube hydraulic conveying device or oil tube hydraulic lifting device is arranged on the front side or the left side of the well mouth, the magnetic screw protector is arranged at the upper end or the lower end of the oil tube of an oil tube hydraulic lifter, and a workover treatment vehicle is arranged on the right side or the left side of the well mouth. The well mouth pneumatic slip and the inlet of the hydraulic clamp pneumatic throttle are connected with an air source of the workover treatment vehicle, and the oil tube hydraulic lifter and the oil tube hydraulic conveying device are connected with a hydraulic source of the workover treatment vehicle.

Description

technical field [0001] The invention relates to a wellhead comprehensive operation device for oilfield workover operation, which changes manual and complex high-strength operation procedures into automatic operation procedures. Background technique [0002] At present, in the process of conventional oilfield workover operations, the wellhead operation often requires the cooperation of two people to complete the operation procedures such as tripping, connecting and unloading the tubing, etc. During the construction, it often encounters such as poor ground environment, improper personnel coordination, dismantling the elevator and loading and unloading. The cumbersome unloading of the protective wires not only increases the labor intensity of the workers but also increases the construction risk, which is not conducive to safe production. The purpose of the research and development of this device is to solve the above problems. A series of operations can be completed by a single...
