针对目前油田注水系统缺少地下系统能耗评价指标，且地上系统能耗指标不完善的问题，从不同油藏类型、区块注水效果角度提出了注水地下系统的能耗评价指标。研究了主要的储层参数——渗透率、孔隙度、饱和压力、地层水矿化度等与地面注水系统重要参数标准单耗的关系，综合了地面注水和油藏注水与采收效果评价体系，以注水能耗替代注水量，实现油田开采效益最大化；新增了站效、管网能量利用率为注水地上系统的能耗标杆指标。从而建立了完整的地上地下注水系统的评价指标体系，综合评价了整个注水系统的能耗现状。为衡量注水系统能耗状态提供了具体完整的标杆指标。

In order to solve problems including lack of underground system energy consumption index on oil field water injection system and deficient over ground system energy consumption index, this article puts forward the energy consumption index of underground water injection system according to water injection effectiveness in different reservoir types and blocks. Major Reservoir parameters including permeability, porosity, saturation pressure, formation water salinity were analyzed to find relationships with essential standard unit energy consumption parameters on ground water injection system as well as the pressure and quantity of flow on wellhead. The research synthesizes the effectiveness assessment systems of ground water injection and reservoir water inject and recovery; oil field exploration profit is maximized with water injection energy consumption substituting water injection quantity. By adding station effectiveness and pipe network energy efficiency as energy consumption index on ground water injection system, a completed ground and underground water injection assessment index were established. Such index assists to evaluate the energy consumption of the whole water injection system and provides guidance for evaluating energy consumption condition of water injection system.
