摘要
本文根据油井系统试井测试结果,对IPR曲线出现拐点的原因进行分析与讨论,提出了湍流渗流附加粘度概念,推导出IPR曲线拐点计算式,并给出出现拐点的判断式。
This paper analyses and discusses the reason of flexpoints on IPR curves using the result of step-rate testing, proposes a concept of turbulent and seepage flow extra viscosity,derivates a computation formulus of flexpoints on IPR curves,and gives a determination formulus of flexpoints.
