| 摘 要： | 渗流的基本规律达西定律,是100多年前法国水利工程师达西提出的,他是通过液体实验得到的。对于气体渗流来讲,存在着滑脱效应,特别是在低渗、低速和低压时,滑脱效应更为显著。在考虑了气体渗流的特点后,结合分子扩散理论得到了考虑滑脱效应的气体渗流速度方程,为进一步开展低渗透气藏渗流理论研究,油藏工程研究和动态分析建立了基础。

| 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 diffusiontheory. It is a theoretical foundation for further study on per-meable theory, reservoir engineering, and performance analysis in low gas permeability reservoirs. |

| Keywords: | gas flow through porous media slippage low permeability diffusion |
