摘　　要：由于长冲程液压抽油机具有采油效率高、运行平稳和经济效益高等优点,在国内外均得到重视。基于此,创新地设计了一种新型长冲程节能液压抽油机,该机采用了双井平衡结构,使得一侧抽油杆下降的重力势能和动能直接为另一侧抽油杆的上升提供动力,从而减小了装机功率,实现了系统的连续性抽油;同时利用比例流量调速控制原理,使压力和流量同时满足负载的要求,并实时做出适应调节,达到较高的控制精度,产生了显著的节能效果。Long-stroke hydraulic pumping units have been valued at home and abroad because of the merits such ashigh efficiency of exploiting oil, steady running, good economic benefits and so on. A new long-stroke energy-savinghydraulic pumping unit was designed innovatively based on this. Adopting balanced structure of Double Wellsmakes the potential energy of the downward sucker rod at one side supply power for rising of the sucker rod at theother side, which decreases the power of installation and realizes continuous pumping oil. At the same time, utilizingthe technology of proportional flow control principle for adjusting speed makes the pressure and flow meet the requirementof load simultaneously and makes real-time adaptive adjustment, which reaches higher precision of controland brings remarkable effect of energy-saving.
