大庆油田注水用电占全油田总用电量的一半左右。从1978-84年,该油田主要从机械设备及工艺方面进行了一系列更新换代和改造,1984年与1979年相比节电3.8亿千瓦小时,折合人民币3千万元。在工艺上尽量选用大泵,减少注水泵及干线压差,换大泵不换电机,减少管网和配水损失等,预计1985年底可节电4.7亿千瓦小时。 Daqing oilfield water injection electricity accounted for about half of the total electricity consumption. From 1978 to 1984, the field mainly carried out a series of upgrading and transformation from mechanical equipment and technology. In 1984, compared with 1979, it economized 380 million kilowatt-hours, equivalent to 30 million yuan. As far as possible in the process of selection of large pumps, reduce the injection pump and the main line pressure, the pump does not change for the motor to reduce the loss of pipe network and water distribution is expected to be saving by the end of 1985, 470 million kilowatts hours.
