摘　　要：大庆油田某大型注水系统由于井口注水量持续增加,导致能耗较高且呈逐年上升趋势;优化系统内各注水站机泵的启停方式对油田的节能降耗具有重要的作用;针对该问题,建立了能耗评价指标及其用能单元的能量平衡分析模型,并对能耗计算结果进行分析与评价,确定了能耗分布规律,找到了用能存在的薄弱环节。运用注水泵启停方案优化算法理论得到注水泵开停调整的方案。现场应用结果表明,注水单耗下降0.23k W·h/m^3,耗电量降低3.5%。Due to the continuous increase of water injection volume at the wellhead in a large water injection system in Daqing oilfield, the energy consumption is high and it is increasing year by year. Optimizing the start-stop mode of the pumps in each water injection station plays an important role in energy conservation and consumption reduction of the oilfield. In this paper, the energy balance evaluation index and the energy balance analysis model of the energy consumption unit were established, and the energy consumption calculation results were analyzed and evaluated. The energy distribution law was determined and the weak links of energy use were found. The scheme of the start-stop adjustment of the water injection pump was obtained by using the theory of the optimization of the injection pump start-stop scheme. The field application results showed that the unit consumption of water injection was reduced by0.23 kW·h/m3, and the power consumption was reduced by 3.5%.
