| 摘 要： | 基于质量守恒原理,建立了油水两相地层瞬态渗流的数学模型。通过定义油水两相拟压力函数,将渗流数学模型线性化,在获得数学模型解后,推导出在地层中为油水两相渗流的油水同产井的产能方程,从而建立了油水同产井瞬态流入动态关系曲线的理论,由此,可以作出油水同产井的瞬态流入动态关系曲线,为油水同产井的动态分析提供了理论基础。

| Abstract: | Based on principle of the mass conservation, the mathematical model of oil-water two-phase transient flow was set up,after defined the oil-water two-phase pseudo-pressure function,the mathematical model was linearized. After obtaining solution of mathematical model, we derived the two-phase productivity equation of oil-water well with formation damage. Therefore,the theory of transient inflow performance relationship curve for oil-water well was established. The transient inflow performance relationship curve of oil-water well could be calculated by the productivity equation. The research in this paper provided the theory supports for the performance analysis of oil-water well. |
