分析了游梁抽油机的负载特性,介绍了开关磁阻电机(SRM)的工作原理及其应用于抽油机电机的特点和优势,并分析探讨了SRM的控制结构及应用于抽油机系统的控制策略。基于模拟抽油机负荷特性建立的SRM试验平台进行了测试,结果表明SRM应用于抽油机有很高的运行效率和节能效果。SRM本身具有结构简单、可靠性高、控制灵活、调速性能好、运行效率高、温升低等优点,将其应用于抽油机系统有其独特的先天优势,能提高整个抽油机系统的运行效率和实现较好的节能效果。应用于新疆油田采油厂现场的测试结果进一步验证了该结论。

The load characteristics of the beam pumping unit were analyzed. The working principle of the switched reluctance motor (SRM) and its characteristics and advantages for applications in the pumping unit motor were briefly introduced. The control structure and control strategy for the SRM used in the pumping unit system were analyzed. The experimental platform of the SRM based on the simulated pumping unit load characteristics was built and tested. The results showed that the SRM was applied to the pumping unit with high operating efficiency and energy saving effect. The SRM had the advantages of simple structure, high reliability, flexible control, good speed regulation performance, high operating efficiency and low temperature rise. Its application to the pumping unit system had unique inherent advantages and could improve the whole operating efficiency of the pumping unit system and realize better energy saving effects. The field test results at the Xinjiang Oilfield production plant further verified this conclusion.
