气体渗流气体在多孔介质中的流动。气体的组成可能是单一的，也可能是组分恒定的多组分混合物。气体渗流在油气田开发、化学工程、冶金、土工及土壤改良中都有较广泛的应用。由于气体粘度低、密度小、压缩性大，与滴状液体相比，气体渗流具有许多特殊性，其解决方法也更为困难。气体流动的特殊性主要表现在气体压缩性的影响、非达西流动（见达西渗流定律）和非等温流动的影响以及滑脱效应等。由于上述诸因素，气体渗流遵循非线性二阶抛物型偏微分方程。对于等温线性达西流动，一般的非线性微分方程简化为拟线性微分方程。这是当前研究得比较充分的一类问题，已有了一组精确自模拟解和几种近似解。关于一般情况，则以虚拟压力为未知量，把方程化为拟线性方程后，求其数值解。根据这些解可以分析、计算气田开发动态和生产指标等。参考书目R.
