A mathematical model of landfill gas migration was established under presumption of the effect of gasslippage.
考虑气体滑脱效应条件下，建立了垃圾填埋场气体渗流的数学模型。

The obvious slippage effect 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 has advantage on paraffin removal and broken down and decreasing liquid slippage losses as well as saving high pressure injecting-gas.
