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。
This paper considers the influence of displacement conditions on the two-phase seepage process. A two-phase seepage equation considering the change of quasi-π (= K / σ-gradp) is established, and the solution method is given. The mechanism of the two-phase seepage flow under this formulation is studied and the Buckley-Leverett theory is generalized.
