摘　　要：大型注水管网系统结构复杂 ,涉及的井点、管网节点多 ,且压力、流量互相耦合 ,注水站排量合理分配难度大。以流体力学基本理论为基础 ,利用“压力谷”的性质 ,根据注水管网特性 ,建立了注水管网的基本模型 ,并在满足注水量和管路阻力损失最小的前提下 ,给出了一种确定大型注水系统注水站设计排量和运行排量的方法。实例计算表明 ,利用该方法调节大型注水系统注水站排量 ,可以使注水站和管网同时达到最优运行状态 ,并且能够科学地计算注水站的设计排量。A complex pipe pattern concerns a great amount of wells and nodes. The coupled pressure and flow rate make it difficult to allocate the running rate and to decide the design rate of a water-injection station in a large-scale system. On the basis of the hydromechanics theory, a basic model for determining the pattern of water-injection pipe was established considering the property of “pressure valley' and characteristics of the water-injection pipe pattern. A method for determining the design rate and running rate of a water-injection station in a large-scale water-injection system under the condition of minimizing the allocated water-injection volume and pipe friction loss was proposed. The calculated results show that this method can be used to control the water-injection station and determine the design rate. The optimum operation of water-injection station and pipe pattern can be achieved simultaneously. This study gives a theorical support for a large-scale water-injection system.
