Abstract

The invention relates to a double-control tubing device for petroleum workover operation and a using method thereof. The device comprises a shell, a lifting block assembly and a tubing clamp assembly, wherein lifting block assembly opening mounting grooves are respectively formed in two ends of the shell; a tubing clamp assembly mounting groove is formed between the lifting block assembly opening mounting grooves; the lifting block assembly comprises a lifting clamping block, a lifting clamping block driving device and a lifting clamping block baffle which are correspondingly mounted in the lifting block assembly opening mounting grooves; the tubing clamp assembly comprises a manipulator main body, a manipulator tubing clamp and a manipulator tubing clamp limiting piece which are mounted in the tubing clamp assembly; the manipulator tubing clamp is rotationally arranged on the manipulator main body by virtue of a pin shaft; a through slot used for mounting the manipulator tubing clamp limiting piece is formed in the shell; the manipulator tubing clamp limiting piece comprises a tubing spring guide rail, a tubing spring push plate and a spring. The double-control tubing device has the advantages of simple structure, reasonable design, convenience in use and simplicity in repair and maintenance, the equipment cost is reduced, the labor intensity of manual labor is alleviated, and the field operating efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of oil production and workover downhole operations, in particular to a device for lifting and lowering oil pipes controlled by two people in oil well workover operations and a method of use thereof, mainly used for straightening oil pipes and lifting rings when lifting and lowering oil pipes. Background technique [0002] At present, the downhole operation process of oil production and workover is complicated, the labor intensity of the operators is high, the working environment is poor, and the safety factor is low. Domestic workover operations for lifting and lowering the tubing can be roughly divided into two types: the first type, the wellhead is operated by two to three people to complete a series of actions, which requires the tacit cooperation of the staff, otherwise it will easily lead to knocking, bumping, injury, and disability. The second type is to import high-precision workover equipment, but th...
