通过多年实践,大庆油田在节约注水用电方面摸索出了一整套成功的经验。据统计,1984年注水用电比1979年节约3.8亿kW·h,折合人民币3千多万元。目前,大庆油田平均注水泵效居全国各油田之首,如果各油田注水泵效能达到或接近大庆油田的水平,将会取得十分可观的经济效益。笔者有鉴于此,特将近几年来大庆油田在注水设备方面所做的工作概述如下。 Through years of practice, Daqing Oilfield explored a set of successful experiences in saving electricity for water injection. According to statistics, in 1984, water-injection electricity saved 380 million kW · h from 1979, equivalent to more than 30 million yuan. At present, the average water injection pump Daqing oil field in the country’s first oil field, if the performance of water injection pumps in various fields at or near the level of Daqing Oilfield, will achieve very substantial economic benefits. In view of this, I hereby give an overview of the work done by Daqing Oilfield in waterflooding equipment in the recent years.
