Abstract

The invention relates to a workover device in drill floor type, used in non-manned operation under the oil well, wherein it is formed by driving control room 1, thick support post 2, discharge tube 3, lifter 4, amplitude-variable hydraulic cylinder 5, support post base 6, well-open hydraulic blowout preventer 7, drill floor hydraulic base 8, fixing hydraulic clamp disc 9, back tyre, back driving bridge 10, hydraulic clamper 11 with flexible sliding channel 11, hydraulic gear box 12, high-pressure gear pump 13, hydraulic torque converter 14, front tyre, front driving bridge 15, engine 16, frame and drill floor 17; the front part of frame 17 is arranged with driving control room 1, engine 16, hydraulic torque converter 14, hydraulic gear box 12 and high-pressure gear pump 13, while the back part has fixing hydraulic clamp disc 19, support post base 6, and hydraulic clamper 11; the support post base 6 is mounted with thick support post 2, discharge tube 3 and lifter 4. The invention can automatically set discharge tube and improve the working efficiency.

Description

Technical field: [0001] The invention relates to a mechanical device used for downhole workover operations of oil and water wells in oil fields. Background technique: [0002] The workover machine (referred to as the workover machine) is the main equipment used by the downhole operation team of the oil field to carry out the downhole workover operation of oil and water wells. At present, the various workover rigs or well drilling rigs used on site are similar in overall structure. They all use the engine to drive the drum to rotate through the gearbox and angle transmission box; The movable block is connected with the drum through the wire rope system; the drum rotates, and the traveling block is reciprocated up and down through the steel wire rope, and the oil pipe is lifted or lowered by the elevator installed on the traveling block to achieve the purpose of raising or lowering the oil pipe. The existing workover rig must be operated by someone at the wellhead during the ...
