Kneeling machine, namely the trough-typePump jackIt is a traditional pumping equipment widely used in oilfields, usually composed of ordinary ACAsynchronous MotorDirectly drag. The crank is equipped with counterweights.Balancing BlockDriveoil pumping rodDrive down the welloil pumping pumpPerforms a fixed-cycle up-and-down reciprocating motion to transport oil from the well to the surface. Within one stroke, as the pumping rod rises or falls, the motor operates in the electric or generating state. During the ascent, the motor absorbs energy from the grid to operate in an electric mode; during the descent, the motor's load property is potential, coupled with downhole negative pressure, which causes the motor to operate in a generating state, converting mechanical energy into electrical energy and returning it to the grid.
However, the situation of the oil layer in the well is particularly complex, with richoil wellThere is a distinction between oil wells with low oil and those with thick oil, and there are differences between thin oil wells and thick oil wells. The constant speed application problem is obvious. If we ignore these, when it comes to the oil pump itself, problems such as wear-related gaps between the piston and the liner are difficult to solve. Moreover, factors such as sand, wax, water, and gas in the oil from changing formations have a great impact on the amount of oil extracted per stroke. It seems that only by adjusting the speed of the drive can we achieve the best control.
After introducing the speed regulation transmission, it is possible to adjust the stroke frequency of the pumping unit and separately regulate the speed of the up and down strokes based on the underground conditions. This not only improves the pumping unit's filling coefficient but also reduces the leakage of the pump, thereby achieving a larger oil production. In particular, the use of variable frequency speed regulation not only eliminates the start-up shock but also solves the conservative selection and long-distance transmission issues.Power FactorLow performance and other issues, while achieving energy saving and efficiency, can also improve the life of the entire machine. Especially the life of the oil pump, reducing mechanical failures and improving reliability.
