Abstract

The invention discloses a mechanization workover treatment system capable of replacing wellhead manual operation. The mechanization workover treatment system comprises a work platform system, an automatic lift sub system, an automatic makeup and breakout system, an oil pipe righting, pushing and pulling system, an oil pipe lifting system, a ground tube bank system and a control system. The lower end of the work platform system is connected with a wellhead casing spool through a flange; the automatic lift sub system and the automatic makeup and breakout system are fixed to the work platform system; the oil pipe righting, pushing and pulling system is connected to a base of the automatic makeup and breakout system through a hinge pin; the oil pipe lifting system is installed on one side of the automatic makeup and breakout system; and the ground tube bank system is arranged on any side of the oil pipe lifting system and is matched with the oil pipe lifting system to achieve transferring of an oil pipe, and the other systems are connected with the control system. According to the mechanization workover treatment system, unmanned wellhead operation is achieved; the labor intensity of a worker is reduced; the work safety is improved; and it is ensured that pipe columns are smoothly run and pulled.

Description

technical field [0001] The invention relates to the mechanized workover operation technology of the petroleum industry, in particular to a mechanized workover operation system which replaces the manual operation of the wellhead. Background technique [0002] Workover operation is an important link in the production process of oilfields. It has been a labor-intensive industry for many years. At present, most oilfields use traditional equipment for operations, and generally require more than 5 workers to work together. One driller operates the well drilling rig or repairs The well rig lifts and unloads the tubing, two workers lift the elevator at the wellhead, unhook the lifting ring, push and pull the hydraulic tongs to unload the tubing buckle, and two workers drag the tubing on the well site, responsible for the transportation of the tubing between the wellhead and the tubing row and the discharge of the tubing . Especially for minor wellhead repair operations, the working...
