摘要
目前,用于油田抽油机井上的节能控制技术种类较多,应用范围广。现场测试表明,这些控制技术的节电率与电动机负载率有较密切关系。通过分析抽油机电动机负载率与电动机实际运行效率关系,能确定抽油机电动机的负载率对节能控制技术应用效果的影响。试验结果表明:抽油机井上应用节能控制技术时,可根据电动机实际负载率针对性选用节能技术,有功节电率可提高4.24个百分点;根据抽油机载荷的平衡状况,可采取相应的节能平衡改造技术,通过改善抽油机的平衡效果,可进一步降低油井的能耗损失。
At present, there are many kinds and quantities of energy-saving control technologies applied in oil field pumping wells. Field tests show that the power-saving rate of these control technologies is closely related to the load rate of motor. By analyzing the relationship between motor load rate and actual operation efficiency of pumping wells, the influence of motor load rate level on the application effect of energy-saving control technology can be determined. When selecting energy-saving control technology for pumping wells, energysaving technology can be selected according to the actual load rate of the motor. The test results show that the active power-saving rate can be increased by 4.24 percentage points, and the energy consumption loss of the oil wells can be further reduced.
