摘　　要：采用液力偶合器传动箱动力机组,将调速电动机、偶合器及齿轮减速箱组合为一个动力单元可降低游梁式抽油机的系统能耗。在分析抽油机液力偶合传动原理的基础上,指出液力偶合传动装置采用双速电动机作为动力机,取消了胶带传动,偶合器使电动机的峰值电压降低,可降低冲击载荷30%-40%,同时对抽油机液力偶合传动装置进行了6口井的现场应用。应用结果表明：抽油机液力偶合传动使电动机功率由37 k W降至30 k W,平均日耗电由234 k W·h降至191 k W·h,节电率达18.37%。所得结论对老油田抽油机节能改造具有参考价值。Using the hydraulic coupling gearbox power unit,and integrating the adjustable speed motor,coupling and gearbox to one power unit could reduce the energy consumption of the beam pumping unit. Based on the analysis of pumping unit hydraulic coupling transmission principle,it is known that the hydraulic coupling transmission device replaces the belt drive with two-speed motor as the power machine,thus reducing the motor peak voltage,which could reduces the impact load of 30% to 40%. The hydraulic coupling transmission has been applied in six wells. Application results showed that the motor power has been driven down from 37 k W to 30 k W,with the average power consumption down from 234 k W·h to 191 k W·h and electricity saving rate of 18. 37%. The conclusion could provide reference for the pumping unit energy saving modification in mature oil field.
