摘      要：The frequency converter has been applied in the beam pumping unit, but the field application is still immature, and the energy saving effect is not ideal. This paper briefly analyzes the movement law of the beam pumping unit, and makes a proper simplification of the suspension point load. It derives the work done by the motor in one stroke of the steam head, and combines the oil recovery per unit time of the pumping unit. The operating law of the inverter when the ratio of motor energy consumption to oil production is the smallest. Finally, through simulation analysis, it is verified that the energy consumption of the slow and fast operation mode is lower than that of the constant speed operation mode.
