在进入高含水期的油田开发中,潜油电泵得到广泛应用.而如何提高其采油系统效率,降低电泵采油井耗电量,成为油田节能减排工作的重点.设计了一种新型智能潜油电泵有载调压变压器,分析了最佳运行电压的确定方法.给出了结构组成及工作流程,进行了室内外的现场实验.结果表明,该装置可以有效地选择最佳电压,节电效果显著.%In the exploiting oil fields in the stage of high water-cut, the submersible pump has been widely applied , whereas how to improve the oil recovery systems efficiency, reduce power consumption of pump wells became the focus of energy conservation field. A new intelligent on-load tap-changer transformer of the electric submersible pump is designed. The optimum operating voltage is analyzed, and the composition and the working processes are provided. Finally, the indoor and outdoor experiments are carried out. Experimental results show that the device can effectively select the best voltage, and the effect of power conservation is remarkable.
