抽油机是油田主要的机械采油方式,也是油田主要能耗设备。抽油机井的系统效率是抽油机在将井内液体举升至地面所耗的有效功率与系统输入功率的比值。通过对机采井系统效率的理论计算,分析了系统效率的构成及影响因素,最后,指出提高机采井系统效率的措施和方法。
Pumping machine is the main oil field mechanical oil production, but also the main energy equipment in the field. The system efficiency of the pumping well is the ratio of the effective power consumed by the pumping unit in lifting the liquid in the well to the ground to the system input power. Through the theoretical calculation of the efficiency of the mechanical recovery system, the composition and influential factors of the system efficiency are analyzed. Finally, the measures and methods to improve the efficiency of the mechanical recovery system are pointed out.
