通过平均功率法提高抽油机系统效率

Raises the system efficiency of pumping unit through the average power law

探讨了抽油机平衡度与抽油机系统效率的影响关系,同时分析了抽油机平衡调整的本质和终极目标,提出了一种新的抽油机平衡调整方法——通过对电机功率曲线进行付立叶分析而确定平衡块重心位置的方法。在现场对47口抽油机电机功率曲线进行付立叶分析后实施了调整措施;系统效率提高了3.05%,达到了油田增产降耗、延长系统使用寿命、降低操作成本的目的。

This article has discussed the influence relations about pumping unit trim and the system efficiency of pumping unit,simultaneously has analyzed essence and the ultimate objective of the pumping unit trimming,has proposed one new method to trim pumping unit-that is the method to determine the counterbalance center-of- gravity position through setting up the leaf analysis of the electrical machinery power trace pays.It has implemented the adjustment measure after electrical machinery power trace of 47 pumpin...
