摘要
在非达西渗流二项式和两相渗流“相渗透率”(有效渗透率 )概念的基础上 ,提出了两相渗流“相速度系数”(有效速度系数 )的概念 ,建立了气液两相渗流数理模型 (微分式 ) ;针对气水同产井的特点建立了气水同产井流入方程式 ,提出了已知一个相对稳定生产点参数时的求解方法 (一点法 ) ;通过大量计算及无因次数据曲线拟合 ,给出了可用一点法进行动态计算的无因次方程和无因次曲线图版。
On the basis of non-Darcy percolation binomial and effective permeability of two-phase percolation,the concept of effective velocity factor of two-phase percolation is proposed and the mathematical model of gas-liquid percolation is established.Based on the features of gas-water well,the equation of gas-liquid percolation is built and its calculation methods are proposed.Through plentiful calculation and dimensionless data curve fit,dimensionless equation and dimensionless typical curve graph are given.
