高压大功率注水电机是油田耗电大户，如何通过技术改造降低其电耗是各有关单位所普遍关心和重视的问题。以孤东采油厂为例，对高压大功率注水电机实施变频改造的必要性、可行性及经济效益进行了全面分析。认为随着高压变频技术的日臻成熟和价格的逐步下降，可以推广应用。
High-pressure high-power water injection motor is a large oil field power consumption, how to reduce its power consumption through technological innovation is concerned by all concerned units and the importance of the issue. Taking Gudong Oil Production Plant as an example, a comprehensive analysis on the necessity, feasibility and economic benefits of high-pressure high-power water-injection motor is given. It is believed that with the high-voltage frequency conversion technology becoming more mature and the price gradually declining, it can be popularized and applied.
