长庆油田注水管道经济流速确定方法

Determination of Economical Flow Rate of Water Injection Pipeline in Changqing Oilfields

注水管道运行参数最优化是油田注水系统高效、节能运行的重要手段。文章考虑油田注水管道自身特点,结合流体力学和经济评价手段,推导了长庆油田注水管道经济管径和经济流速关系式,计算了西北地区油田部分在用注水管道的经济流速范围,可为注水管网的设计计算提供借鉴。

The operation parameters optimization is a prominent approach for high efficiency and energy saving of oilfield water injection system. By pondering upon the feature of water injection pipeline and from fluid mechanics principle and economics evaluation methods,this paper derives the formula of the relation between economical pipe diameter and economical flow rate for Changqing Oilfield,and uses them to calculate economical flow rate range for partial water injection pipelines of Northwest oilfields.The results provide reference for design calculation of water injection pipeline network.
