摘要：

柔性控制运转技术用于改善游梁式抽油系统的采油工作过程，而采用椭圆速率驱动电动机是实现该技术的方案之一。为了探寻椭圆速率驱动与常规圆速率驱动时抽油泵内阀球运动规律，分析了两种工况下的阀球滞后开启情况，并建立流固耦合仿真模型分析了固定阀的受力规律，得到了两种工况下阀球运动的差异性，最后通过台架实验验证了理论分析的正确性。结果表明，椭圆速率驱动下阀球开启和到达最大升程的速率比常规圆速率驱动慢，但落座更快，可有效防止漏失，从而达到提高采油效率的目的。

Abstract:

The flexible control operation technology is used to improve the oil production process of the beam pumping system, and the use of an elliptical speed drive motor is one of the solutions to realize this technology. In order to explore the law of movement of the valve ball in the pump with elliptical velocity drive and conventional circular velocity drive, the delayed opening of the valve ball under two working conditions was analyzed,and a fluid?solid coupling simulation model was established to analyze the force law of the fixed valve. The difference of the valve ball movement under the two working conditions was obtained. Finally, the correctness of the theoretical analysis was verified by the bench experiment. The results show that the rate of opening and reaching the maximum lift of the valve ball under the elliptical velocity drive is slower than that of the conventional circular velocity drive, but it seats faster, which can effectively prevent leakage and achieve the purpose of improving oil recovery efficiency.

Key words: Oil recovery, Flexible control, Elliptical rate, Fluid?solid coupling, Fixed valve
