气水两相流井产能分析方法研究

Study of Productivity Analysis Method for Gas-Water Well.

从渗流力学的基本原理出发 ,基于质量守恒原理 ,建立了气水两相地层稳定渗流的数学模型。在获得数学模型解后 ,考虑地层损害和非达西效应的影响 ,推导出气水两相流井的二项式产能分析方程 ,从而建立了气水两相流井稳定流入动态关系曲线的理论。由此 ,可以作出气水两相流井的流入动态关系曲线 。

Based on principle of mass conservation,this paper sets up mathematical model of gas water two phase steady flow.After obtaining solution of mathematical model,we deduced the binomial productivity equation of gas water well with formation damage and non Darcy effect,therefore,theory of steady inflow performance relationship curve for gas water well is build.Steady inflow performance relationship curve of gas water well can be calculated by the binomial productivity equation.The research in this paper supplies the theory basis for productivity performance analysis of gas water well.
