摘要:
目前国内大多数低渗透油田由于单井产量低(3.0~50.0 m3/d)，主要采用游梁式抽油机机械采油方式生产，面临的主要问题是机采系统效率水平低(平均21%~28%)、能耗损失严重；通过游梁式抽油机井系统关键节点运动规律、功率曲线特征分析，总结归纳出提高机采系统效率的3个要点，提出了3个针对性技术对策，以开关磁阻电动机高效驱动、抽油机柔性运行为代表的提效关键技术矿场试验效果显著，为油田机采系统效率提升提供了新的思路和借鉴。
At present, because of the low yield of single well (3.0-50.0 m3/d), the beam pumping oil mechanical system has been used for oil production in the most of domestic low permeability oilfields. The main problem was low efficiency of the mechanical system (21%-28% on average) with serious energy loss. By analyzing the key node movement of rod pumping system and the feature of power curve, 3 key points are summed up to improve the pumping system efficiency, and 3 specific technical measures are put forward, the key technology of field experiment effect of high efficient driving on switched reluctance motor and flexible movement of the pumping unit is obvious, it provides a new idea and reference for improving the efficiency of oil pumping system for oilfields.
