增压泵恒压注水自动控制系统的开发与应用

Development and application of constant injection pressure automatic control system

根据油田恒压注水工艺要求 ,开发出一种增压泵恒压注水自动控制系统。该系统为闭环自动控制系统 ,利用变频调速技术、压力检测技术 ,自动跟踪调节电动机转速 ,改变增压泵的排量 ,使注水压力保持在设定的压力范围以内 。

The automatic constant injection pressure control system is developed to meet the requirement of constant injection pressure in the injecting operation. This system is closed loop, it can change the volume of pump by the variable frequency technique and the pressure detecting technique. Meanwhile, the injection pressure can be maintained in the range required.
