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 of oilfield water injection system was analyzed to determine the energy loss in the production process, mainly in the water injection pump station pressure drop and water pipe network outside the station and found that the injection pump speed, pump pressure can be reduced , Which is helpful to optimize the operation of the whole pipe network system.An energy saving calculation formula applying frequency control and hydraulic speed adjustment clutch is given.The energy saving effect of the water injection pump unit is estimated and a large scale water injection system Optimize the operation and control of the program, and with the initial development of the computer software to simulate the water injection system in Xingnan Oilfield.The calculation results show that, through the regulation and control of a speed governing unit, you can optimize the operation of the entire water pipe network, so that The entire water injection system can use the best.If this program for speed control and operation control, Xingnan oilfield water injection system can save 100kW d.
