Application of Mass Conservation Principle to Porous Media Percolation

Abstract

Abstract: The universal principle of mass conservation is introduced into porous media fuid mechanics followed by obtaining the general form of the mass conservation equation which used for oil-gas or oil-water percolation and media-deformed rocks is verified. The result shows that the general form of mass conservation can be applied to describe the percolation features of the porous media fuids in single phase, multiphase and solid phase in deformation media. Introducing mass density allows the equation to be simple, understandable and applicable. In addition, the definition of flowing velocity are modified and perfected, testifying the relationship between real velocity and flowing velocity.

Key words: percolation, velocity, mass, conservation principle
