Description

Automatic screwing-on and unscrewing device for petroleum well workover

Technical Field

This technical scheme relates to oil machinery technical field, especially a petroleum well workover is with automatic break out device that goes up.

Background

In the field of petroleum machinery, workover is an important means for guaranteeing normal production of an oil well and is an important work content of operators. In the well repairing process, a large amount of oil pipes need to be lifted out of and put into the oil well, wherein the screwing-on and unscrewing action of the oil pipes is one of the most labor-intensive tasks of operators. When the oil pipe is buckled, the oil pipe is always in an inclined state in the process of being lifted by the elevator, so that when the oil pipe is separated from the ground, the oil pipe swings due to the motion inertia of an object, and at the moment, an operator can block the tail of the oil pipe by using the body to reduce the shaking degree of the oil pipe, so that the body burden of the operator is increased; the traditional tubing tong is hung in the air when being idle, when the operation of putting on and taking off the oil well is needed, an operator needs to operate a suspension system and push and pull the tubing tong to the position of the wellhead of the oil well at the same time, then the operation of putting on and taking off the oil well is started, and because the jaw plate frame, the gearwheel and the shell can not automatically align the gap, the oil pipe can not come out smoothly after entering the oil well, and the operator needs to align the gap by experience; when the personnel work for a long time and are tired, the problem that fingers are cut off by biting at the jaw engagement position is easily caused by the stretching of hands in the jaw operation; in an actual working site, a steel wire rope is often tied between the tail of a back tong of the oil pipe tong and a derrick, so that the back tong is prevented from rotating under the reverse torque formed in the process of shackle mounting on a main tong, but after the steel wire rope is used by long-term severe impact force, the steel wire rope is easy to break suddenly and throw off, and workers are injured by the steel wire rope due to untimely lightning avoidance; in the traditional screwing-in and unscrewing work, operators need to frequently and manually move the elevators, each elevator needs to be moved by two workers, and the operation of screwing-in or unscrewing an oil pipe can be finished only by moving the elevator twice; an operator often stands beside a wellhead of an oil well to carry out makeup and breakout work, and the wellhead sometimes has a blowout phenomenon due to unstable factors in the underground environment, so that the operator is dangerous when standing at the wellhead; because the oil pipe is mainly hung by a steel wire rope on the derrick and has larger concentricity error with an oil well, when the oil pipe is butted with a coupling, dislocation is easy to occur and a butting inclination angle is easy to cause by shaking of the oil pipe; in conclusion, the traditional screwing-unscrewing operation for the petroleum well repairing has the problems of low safety factor, high labor intensity, long time consumption and low efficiency.
