摘要: 本文介绍了在低界面张力条件下,胶结岩心和非胶结岩心的吸吮过程相对渗透率曲线的特性。实验结果发现,非湿相在非胶结岩心中的吸吮过程渗透率大于驱替过程者;而湿相的吸吮过程渗透率则小于驱替过程者。对胶结岩心来说,情况正好相反。这与NAAR在高界面张力条件下所进行的类似实验的结果是一致的。

Abstract:

Characteristics are presented of two phase flow imbibition relative pemeability curves with low interfacial tension. It is found experimentally that at a given saturation nonwetting permeabilities for an unconsolidated porous medium (sand pack) are higher than the drainage permeabilities. The contrary happens for consolidated porous media—imbibition nonwetting permeabilbities are smaller than drainage ones. The ezperimental results obtained in this stud are consistent with those obtained by NAAR with high interfacial tension systems.
