摘要: 据统计,注水开发油田的注水电耗占原油生产总用电的33%~56%,注水节能成为一个迫切需要解决的问题.基于双泵串联的泵控泵技术,利用前置小功率增压泵来调节系统压力和流量,使高压大功率注水泵高效工作.对大型注水泵站的串接泵叠加特性进行了分析,建立了控制系统的数学模型,介绍了系统节能和自动控制原理.以注水泵站的输出压力和流量为目标函数,实现了高压注水泵站的稳定、高效节能和优化运行.

Abstract: The statistics show that the electric power consumption in water flooding development takes up 33%~56% in the total power consumption of oil production.The energy-saving problem is emergent in water flooding system.The pump-control-pump(PCP) technique based on two pumps connected in series is put forward to regulate the output pressure and flux of water flooding system and to make the high-pressure and high-power water flooding pump working with high efficiency by means of preceding booster.The mathematical models for the control system were established on the basis of the superposition characteristic analysis of pumps used in large-scale water flooding station.The automatic control theory and energy-saving principle are introduced.The output pressure and flux of water flooding station are taken as the objective functions,and high efficiency,energy-saving and optimization operation are realized in high-pressure water flooding station.

Key words: water flooding development, water flooding technology, energy-saving, booster, pump-control-pump, mathematical model
