Abstract

Abstract: Darcy’s law, the principle law through porous media, put forward one hundred years ago, was derived by experiments with liquid. For gas flow in porous media, a slippage effect ex-ists, especially when pressure is low, or velocity is low or per-meability is low. Gas flow equation in porous media with a slip-page effect was presented, combining with molecular diffusion
theory. It is a theoretical foundation for further study on per-meable theory, reservoir engineering, and performance analysis in low gas permeability reservoirs.

Key words: gas, flow through porous media, slippage, low permeability, diffusion
