Research on Domestic Long Stroke Pumping Unit

Long stroke pumping unit has the advantages of high production efficiency, long stroke, low speed, and is suitable for mining deep wells, heavy oil wells, high water-cut wells, multi-gas wells and so on. Since the development of our oilfield has entered the late stage, the design and application of long stroke pumping oil machine will enter into a new stage. Based on the classification of domestic long stroke pumping unit, the research status is summarized in the paper, and the working principle, the existing types of long stroke pumping unit technical advantages and existing problems are also analyzed at the same time. The paper points out that the development of pumping unit will be in the direction of no beam, low power consumption, low stroke, general series, intelligent, and high adaptability.
