This paper studies the permeability limits and pore pressure conditions of gas reservoirs with slippageeffect.
为此,研究了具有滑脱效应的储层渗透率界限以及孔隙压力条件。

The obvious slippageeffect for gas flow has been found due to the low gas permeability, and the effect of coal matrix shrinkage on the permeability is also indispensable.
低渗透气藏中的气体渗流具有明显的滑脱效应,同时煤基质收缩效应对煤层渗透率的影响也是不容忽视的。

It is indicated that the main factors affecting low permeability gas reservoir are stress action, start-up pressure gradient, permeability, slippageeffect, and water blocking effect etc.
