谈谈渗流

渗流是流体在多孔介质中的流动，渗流现象广泛地存在于自然界、工程材料、动物、植物中。多孔介质种类繁多，包括岩石(含各类矿藏)、土壤、生物材料和人工多孔介质材料等。渗流理论已经成为人类开发地下水、地热、石油、天然气、煤炭与煤层气等诸多地下资源的重要理论基础。本文从渗流的基本概念、渗流的分类、渗流的影响因素、渗流的特征以及渗流的研究意义等方面进行了阐述。

ON FLOW IN POROUS MEDIA

Flow in porous media (or porous flow) is the manner in which fluids behave when flowing through a porous media. There are many types of porous media, such as rocks (including various types of minerals), soils, biological materials, and artificial porous media materials. The porous flow phenomena widely exist in the natural world, engineering materials and inside the body of plant and animals. The porous flow theory is fundamentally important in exploiting underground resources, such as underground water, geothermal resource, petroleum, natural gas and coal. This article explains the basic concepts, classifications, influencing factors and key characteristics associated with porous flow. The research significance of porous flow is also discussed.
