摘　　要：对油田注水系统的用能进行了分析 ,确定了在生产过程中能量损失主要在注水站内的泵管压差和站外的注水管网 ,发现对注水泵进行调速 ,可以降低泵管压差 ,有助于优化运行整个管网系统 .给出了应用变频调速和加装液力调速离合器的节能计算公式 ,并对注水泵机组的节能效果进行了估算 ,提出了油田大型注水系统的优化运行控制的方案 ,并用初期开发的计算机软件对杏南油田注水系统做了仿真计算 .计算结果表明 ,通过对某调速机组的调节和控制 ,可以优化调度整个注水管网的运行 ,从而使整个注水系统用能最优 .如果按此方案进行调速和运行控制 ,杏南油田注水系统可节能 10 0 0kW d .The energy consumption in a large water\|injection system is analyzed. It is found that the energy lost resulted mainly from the pressure difference between pumps and pipelines in the water\|injection stations and the pipeline networks out of the station. Adjusting the speed of centrifugal pump can reduce the pressure difference between the pumps and the pipelines, which is useful for optimizing the whole pipe networks system. The energy saving formulae under the conditions of installing regulator of variable frequency and hydraulic speed regulator are given. The energy saving results are evaluated. The optimum plan for controlling the Xingnan oilfield water injection system is presented. The simulation calculation of the water\|injection system in Xingnan oilfield is made. The simulating result shows that the water injection system in Xingnan oilfield can save power of 1000 kW/d by using the new technology.
