摘　　要：基于使抽油机井系统效率管理更加精细、节能措施安排更为精准的目的,采用示功图面积计算方法,将系统效率指标细分为地面系统效率和井下系统效率两部分,结合分析主要影响因素试验,以建立多元回归预测模型的方法,绘制出抽油机系统效率动态控制图。而后采用对应的系统效率提升对策,共治理低效井515口,共计实施措施3 385井次,平均系统效率提升7.91个百分点,年共累计节电204.61×10^(4)kWh。结果表明,应用抽油机系统效率动态控制图,能够准确判断出节能潜力,能够提出针对性的提效措施。In order to make the efficiency management of pumping well system more detailed and the arrangement of energy conservation measures more accurate,the method of calculating the area of the schematic diagram is adopted,and the index of system efficiency is divided into two parts including surface system efficiency and downhole system efficiency.Combined with the analysis of the main influencing factors,the of multiple regression prediction model is established,and the dynamic control diagram of pumping unit system efficiency is drawn.Subsequently,the improvement measures of corresponding system efficiency are adopted,with a total of 515 inefficient wells treated,and a total of 3385 measures implemented.The average system efficiency is increased by 7.91 percentage points,and the total cumulative power savings per year are 204.61×10^(4) kWh.The results show that the dynamic control chart of dynamic control chart for pumping system efficiency has been applied,which can accurately judge the energy conservation potential and propose targeted efficiency improvement measures.
