摘　　要：提出了油田大型注水系统优化运行的２类问题，１类是在注水单耗小于规定值的情况下，确定注水系统各注水站水泵运行台数，使注水系统中各注水站实际注水量和分配注水量误差平方和最小；另１类是在注水系统各配水间配注误差不超过规定值的条件下，使注水系统总的能耗达到最小。应用大系统优化理论解决这２类问题时，为减小子系统之间的耦合，按压力谷将注水系统分解为一系列子系统，然后应用动态规划理论和最优化的充分必要条件严格证明了整个注水系统的优化等价于所有子系统的优化。根据上述理论设计了注水系统优化运行的计算方法，并将这个方法编制成计算机软件。这项技术应用于油田注水系统，可节约大量电能，并有效地减小了配注误差。To present two kinds of operation optimation problems in large scale water injection Systems.To solve these problems,we divide the water injection system into a series of subsystems according to pressure valleys and prove that the system optimation on the whole is equivalent to the optimation of every subsystems based on the theories of dynamic programming and optiamtion.A new operation optimation method has been developed for this system by applying the theory of large scale system and this methord has been programmed into a software package.It has been proved that this new methord has the advantages of rapid iterative rate and high calcualtion accuracy.
