Abstract

The invention discloses a well-repairing operation machine. The well-repairing operation machine comprises a base, a well rack and lifting mechanism, a hydraulic system and electrical control system part and a lift sub, wherein the well rack and lifting mechanism is hinged to one end of the base, and the hydraulic system and electrical control system part is installed on the base; the well rack and lifting mechanism comprises a lower lifting support, a guiding standing column, a lifting oil cylinder, movable pulleys, a fixed pulley, a steel wire rope and a guy rope, a lower lifting support ishinged to one end of the base, the guiding standing column is connected with the lower lifting support, the two lifting oil cylinders are arranged on the two sides of the guiding standing column and fixed on the base, the movable pulleys are arranged at the upper portion of the guiding standing column, the fixed pulley is arranged at the lower portion of the guiding standing column, one end of thesteel wire rope is fixed on a connecting block arranged below the movable pulleys, and the other end of the steel wire rope bypasses the fixed pulley and then bypasses the movable pulleys at the upper portion to be connected with the lift sub. According to well-repairing operation machine, low-energy-consumption and high-efficiency well-repairing operation is achieved, and the well-repairing operation machine has the advantages of being high in working efficiency and operation-process controllability, stable in lifting speed and the like.

Description

technical field [0001] The invention relates to a workover operation machine, which belongs to the technical field of petroleum workover equipment. Background technique [0002] In the workover operation, it is necessary to complete various lifting and lowering operations.
