Especially, it is found that there exists three types of relative permeability of water such as concave, convex to the water saturation ax and the reversed "S" pattern. The super-low permeability reservoir is sensitive to pressure, apparent with millipore undersaturation and water blocks. In this study, a new concept of irriducible undersaturation is brought up. And a new mode to describle the process of imbibition dynamics is used to reveal and confirm the mechanism of pinhole enveloping macropore as following: pendular ring of wetting phase gathers→it fills throat→it truncates nonwejting phase . The expression of pressure distribution and the equation of oil production are deduced under conditions of non-darcy linear seepage and non-linear seepage.

当污染物迁移到地下毛细管区后，其向下的运动将整体受到毛细张力的阻碍，污染物要想进入毛细饱和带必须克服油-水界面的进气压力，这时污染物在毛细饱和带顶部聚集以期获取压力，同时将产生以水平方向为主的迁移，最终随着污染物的压力超过其进气压力，导致污染物进入毛细饱和带，在地下水水位上形成一个透镜体。
