针对目前国内外油田低产井开采数量不断增加的现状,为满足采油生产的需要,研制了低冲次抽油机,实现了低冲次采油.给出了低冲次抽油机的结构设计、工作原理、技术参数和低冲次抽油机参数设计计算方法.对现场应用的低冲次抽油机进行了试验和测试,与常规抽油机相比节电效果明显.%Low-yield oil wells at home and abroad increasing number of the status quo, to meet the needs of oil production, development of the low stroke frequency pumping unit to achieve a low stroke frequency oil production. The low stroke pumping unit of structural design, working principle, technical parameters and low stroke pumping parameter design method is discussed. On-site application of low stroke pumping unit is tested and detection. Compared with the conventional pumping unit power saving effect is obvious.
