Darcy law is the principle law of percolation theory,but percolation of low permeability gas reservoir has its specific characteristics because of the simultaneity of kickoff pressure and gas slippage effect,and the study on them seems to be contradicted.
达西定律是渗流的基本规律,但低渗透致密气藏的渗流还有其特殊性,启动压力和气体的“滑脱效应”同时存在,两种现象的研究又似乎相互矛盾。
To figure out the slippage mechanism and flow behavior of gas through porous media,it is necessary to quickly measure the gas slippage factor and absolute permeability of core samples with low-and extra-low-permeability.
为了研究气体在多孔介质中渗流时的滑脱行为机理及其渗流规律,需要快速实验测定气体滑脱因子和低渗、特低渗岩心的绝对渗透率,常规方法须经多次测量方可获得一个滑脱因子和绝对渗透率值。
