The optimization theory and method combined with variable frequency speed regulation technology is applied in this paper to realize efficiency optimization in water injectionpumping stations.
利用最优化原理与方法结合变频调速技术实现注水泵站效率优化控制，以满足油田生产节能降耗的需要。

So the pumping flow can be increased to burden more load with the permission of pumping and injection.
因此在抽水和回灌允许的情况下，可以加大抽水流量，使井承担更大的负荷。

The active systems consist of several pumping systems of varying discharge pressure and flow rates, e. g., high head injection system, low head injection system.
