Digital visual operation system based on oil field workover machinery operation

Abstract

The invention discloses a digital visual operation system based on oil field workover machinery operation, which comprises an operation end and an execution end, and is characterized in that the operation end comprises a control unit, a power supply unit, a man-machine interaction unit and an anti-interference unit. The control unit is connected with the man-machine interaction unit, and the input end of the control unit is provided with the anti-interference unit and a detection unit. The output end of the control unit is provided with a protection subunit and an alarm subunit, the execution end comprises a generator, a motor, a battery pack and a control mechanism, the motor is used for providing power for completion of oil pipe lifting operation, the generator is connected with a brake mechanism of the winch and the battery pack, and the battery pack is connected with the generator and the motor. And the control mechanism controls the battery pack to supply power to the motor. The control unit controls the protection subunit to cut off the power supply, the alarm unit plays corresponding voice to give an alarm to a worker, and compared with the prior art, the service life of the switched reluctance motor can be effectively prolonged.

Description

technical field [0001] The invention relates, in particular, to a digital visualization operating system based on oilfield workover machinery. Background technique [0002] Oilfield minor workover is currently the most commonly used workover operation method in my country's oilfields. It is the most difficult work in oilfields due to its high labor intensity, poor safety, and harsh working environment. Oilfield development has entered the middle and later stages, and the number of workover operations has increased year by year. Sinopec alone has more than 1,600 downhole operation teams, and the annual number of operations is more than 130,000. Minor repair operations in oilfields can be divided into minor repair operations and major repair operations. Minor repairs include major operations such as pump inspection, process change, and sand washing, which is the most common form of operation in oilfields. Simply put, workover operations that can be completed only by lifting o...

Problems solved by technology

The mechanization of sucker rod lifting operation is still a difficult point, mainly because: the domestic minor workover process still has not got rid of the current traditional minor repair process, and the sucker rod lifting operation is difficult to take into account the two actions of elevator suspension lifting and slip support bearing. The operation of the sucker rod adopts the circulation method of two elevators, but it is difficult to realize in the mechanized operation, although some mechanized operation equipment adopts the mechanized equipment that imitates the operator, the effect is not good
