摘要: 本文考虑驱替条件对二相渗流过程的影响。建立了考虑到准数π(=K/σ-gradp)变化的二相渗流方程,给出了求解方法。并对这一提法下的二相渗流机理进行了研究,推广了Buckley-Leverett理论。

Abstract: The effect of displacement conditions on the two-phase flow in porous media is reviewed, Taking into account the variation of dimensionaless parameter π(=k/σ-gradp), a set of equations for two-phase flow is established. A method to solve this problem is proposed and the mechanism of two-phase flow in this case is studied, in amplification of the wellknown Buckley-Leverett theory.
