When gas flows in low permeability porous media,the effect of gas slippage cannot be ignored.It takes many times to obtain gas permeability under different pore pressure of low permeability core with conventional method by linear fitting to get intrinsic permeability and slip factor.Based on the relationship between intrinsic permeability and slip factor,a new unsteady gas permeability experiment method was proposed.The principle of the new method is to fit the inlet pressure decay curve tested and calculated that can be obtained by solving unsteady gas flow equation considering slippage effect according to least square curve fitting,then the wanted intrinsic permeability and slip factor can be acquired and verified through conventional experiment.Compared with steady state experiment,this new unsteady method is more correct,and it greatly shortens the time,and simplifies the experiment process.
