注水井地层吸水规律实验研究

注水开发是油田开发的第一选择。本文通过试验着重分析了指示曲线方法在注水开发过程中的失效原因，总结出水嘴总压损失随流量变化规律。同时，考虑真实油藏下任意井网排布，推导了注水层井底压力与流量随时间变化的关系，提出了瞬时指示曲线分析方法指导流量调配，既满足了油田注水的基本要求又把注水成本控制在合理的范围内。现场试验结果表明，该方法准确、简单、可靠，很好地满足了工程实际的需要，减轻了调配人员的工作强度和工作时间。

Experimental Study of Reservoir Water Injection Regulation

Water injection is the most widely used option in oil field exploitation.In this paper,via experiments,the slop analysis used in water injection operation was analyzed to find the reason of slop analysis invalidation.In addition,the regulation of nozzle pressure loss related to water flux was also acquired in experiments.On the basis of these studies,considering arbitrary well network model,the relation between downhole pressure of injection layer and flux was deduced.As a result,a new method called transie...
