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.
