电潜泵具有结构简单、效率高、抽油量大、维护保养简单方便、占地面积小、容易实现自动控制等优点,已经成为我国油田稳产、高产和获得更好经济效益的采油设备。大庆油田到1999年底为止,电潜泵采油井数占总数的30.9%,而采油量占总数的47.2%。现在已有了更大的发展,电潜泵是增产 Electric submersible pump has the advantages of simple structure, high efficiency, large pumping volume, simple maintenance, small occupied area and easy automatic control. It has become an oil recovery equipment with stable production, high output and better economic benefits in China. Daqing Oilfield until the end of 1999, the number of ESP wells accounted for 30.9% of the total, while the oil production accounted for 47.2% of the total. Now that there has been even greater development, ESPs have increased production
