摘　　要：注水泵是油田注水系统主要设备之一,在整个注水中起着重要作用。随着油田开发相继进入中高含水期,油田回注采出水增多,而采出水腐蚀性强、机杂含量相对高,造成注水泵液力端封面腐蚀磨损速度快、泵效低,注水单耗达7.82 kWh/m^3,造成能源的极大浪费。针对这一问题,对注水泵液力端进行节能改造,将液力端外圆密封结构改造成外圆加平面密封,同时取消连接液力端函体与泵体的定位销。新型节能注水泵机组效率及容积效率均有大幅度提升,平均注水单耗下降到6.27 kWh/m^3,具有较好的经济效益与推广应用前景。Injection pump is one of the main equipments in oilfield water injection system and it plays an important role. With the oilfield development have entered high water- cut period, the amount of reinjection water increases, and its corrosion resistance is strong, as well as relatively high content of the impurity. Therefore, the corrosion speed of hydraulic end of injection pump is higher, the pump efficiency is lower, and the energy consumption of injection pump is as high as 7.82 kWh/m^3, causing great waste.In order to solve this problem, the hydraulic end is transformed. The cylindrical seal structure of hydraulic end is transformed into cylindrical flat seal. At the same time, the positioning pin which connects the body of hydraulic end with the pump body is cancelled. After being transformated, the pump unit efficiency and volumetric efficiency greatly ascend. The average energy consumption is dropped to 6.27 kWh/m^3 which has good economic benefit and application prospects.
