摘要
海上油田注水具有耗能多、压力高、流量变化范围大的特点,选择合适的流量控制方法、降低离心式注水泵能耗具有重要意义。影响离心式注水泵流量调节方式选择和注水泵能耗的因素有很多,从注水要求、流量调节范围、设备占地、设备初始投资和能耗的角度,结合"小流量、高扬程"工况,对离心式注水泵流量调节方式的选择进行分析,并从节能方式、节能原理和节能效果的角度提出建议。
The characteristics for water flooding to offshore oil field are of high energy consumption,high hydraulic head and large flow range.It is significant to choose appropriate flow adjustment methods and to decrease energy consumption.Considering "low flow with high hydraulic head" working condition,the flow adjustment methods of the centrifugal water-flooding pump are analyzed from water flooding requirements,flow adjustment range,equipment occupation,initial equipment investment and energy consumption,and the suggestions are given according the methods,principle and effect of energy saving.
