在油田地面管网系统中 ,动力消耗的主要设备是泵。其效率和投资是影响经济效益好坏的主要因素 ,也是选择泵时应该重点考虑的因素。文章以等额年费用为目标函数 ,压力约束、流量约束等为约束条件 ,建立了泵优选的数学模型 ,并给出了求解方法。计算实例表明 ,文章介绍的泵优选方法是可行的 In the oil field pipe network system, the main power consumption of the pump. Its efficiency and investment are the main factors that affect the economic benefits, but also the key factors that should be considered when choosing a pump. In this paper, the equivalent annual cost as the objective function, pressure constraints, flow constraints and other constraints as the constraints, the establishment of a mathematical model of pump optimization, and gives the solution. The calculation example shows that the pump optimization method introduced in this paper is feasible
