摘要: 高速流动的油井,由于在井底附近地带存在湍流的影响。达西定律的平面径向流动已不完全适用。在文献[1]的基础上,经分析采用了一种简单的方法来确定油井二项式产能方程,即不需要地层静压,只通过井底流压与产油量数据,利用线性回归法,既可建立二项式产能方程,还可求得绝对无阻流量。实例对比分析表明,该方法准确、可靠。

Abstract: Since turbulence effect appears near wellbore in oil well with high-speed flow, Darcy's Law for flat radial flow is incompletely applicable. Reference [1] presented the incomplete binomial equation of oil well similar to gas well under the condition of high speed tur bulence effect. Based on that, this paper proposes an easy way to determine binomial equation of well productivity without regard to for-mation static pressure, established by flowing bottomhole pressure and production data as well as linear regression. Using this equation, absolute open-flow capacity can be obtained. Case study shows this method is accurate and reliable for use.
