Abstract
Many oil fields are full of wind energy. At present, wind power generation technology has catered to oil fields. A larger wind turbine is used to supply power to several pumping units. As a result of the structural characteristics of the pumping unit, the efficiency of the electromotor is very low, which leads to a reduction in the utilization rate of wind energy. At the same time, considering the high cost of large wind turbines, the energy saving effect is not obvious in practical applications. This paper proposes an energy supply model of a pumping unit driven by a small wind turbine and a new wind-motor hybrid structure. Instead of wind power generation technology, wind energy drives the pumping unit directly via a mechanical–hydraulic transmission system. This new mechanical-hydraulic system can optimize the power confluence of wind and electric power. To enhance the efficiency of the motor, a mathematical model and a test station were established. The correctness of the energy conservation method and the mathematical model was verified, and the performance of the wind-motor system was studied.

Summary
Petroleum is the most important traditional energy in the world; it plays an irreplaceable role in modern life and production. Many oil fields in China have tried to use wind power generation instead of grid power to realize energy savings [15] In such situationas, the oil field installs a large wind turbine to drive several pumping units. This paper proposes, for the first time, a late-model wind-motor hybrid pumping unit This mode of wind energy utilization employs a small wind turbine drive beam pumping unit. As power generation equipment is eliminated, the unit cost decreases and wind energy can be utilized more efficiently This method can effectively resolve the existing problems of wind energy utilization in oil fields. The late-model wind-motor hybrid system is characterized by low cost, simple structure, and strong adaptability, making it especially suitable for oil fields in remote areas. By experimentation and numerical simulation, the feasibility of the wind-motor hybrid system is verified
