Oil field well workover operation machine

Abstract

The invention relates to an oil field operation device, in particular to an oil field workover treatment machine. The machine body is arranged on a hydraulic load-bearing traveling gear and is interlocked with the hydraulic load-bearing traveling gear. Hydraulic tongs connected with a telescopic bracket on the machine body can be extended out and retracted with the telescopic bracket. A clip seat is positioned below the hydraulic tongs and is arranged on a well head. An elevator which is suspended onto the machine body can reciprocate up and down. A faucet is positioned above the machine body and the clip seat; a pipe throwing device is arranged on the faucet and the machine body; and a clip unlocking device and a clip locking device corresponding to the elevator are arranged on the clip seat and the pipe throwing device respectively. A righting mechanism and a valve mechanism are further arranged on the faucet. A control cabinet is arranged on the machine body; and the clip seat, the hydraulic tongs, the elevator and the pipe throwing device are connected with a control system in the control cabinet respectively. The oil field workover treatment machine can be assembled and disassembled conveniently and rapidly, thereby not only facilitating transportation, but also changing the positions to meet the requirements of different work. Simultaneously the machine can be laid freely at a well field according to the practical conditions.

Description

technical field [0001] The invention relates to oil field operation equipment, in particular to an oil field workover operation machine. Background technique [0002] Workover operation is an important part of the oilfield production process. It has been a labor-intensive industry for many years. The working environment is harsh, the labor intensity of the operators is high, and there are often hidden dangers to personal safety during the operation process. Especially minor wellhead repair operations are usually carried out in the field, and there are many contents, such as: loading preparations, well cleaning operations, sucker rod lifting, tubing lifting, tubing (sucker rod) measurement, downwashing sand pipe, Sand washing, sand washing pipe, oil pipe lowering, sucker rod lowering, hanging pumping, well delivery, moving down, etc. At the same time, according to the actual situation of oil and water wells, other operations that need to be coordinated include: ash injection,...

AI Technical Summary

Problems solved by technology

With the development of automatic detection and control technology and the emphasis on safe production in oil fields and all walks of life, this long-term operation mode that has been manually completed by workover personnel needs to be changed urgently.
