The universal principle of mass conservation is introduced into porous media fluid 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.

• 摘要将普遍的守恒原理引入了多孔介质流体力学中，得到了质量守恒方程的一般表达式，并用油气、油水两相渗流和变形介质中岩石固相的质量守恒方程进行验证。
