普遍守恒原理在多孔介质中的应用
|
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。结果表明,该通用方程能描述多孔介质流体在不同流动条件下的单相流、多相流和变形介质中流动的渗流特征。而且,引入质量密度后,该方程形式简单并易于理解和应用。此外,对渗流速度的定义进行了改正和完善,并证明了多相流中真实速度与渗流速度的关系。
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. The result shows that the general form of mass conservation can be applied to describe the percolation features of the porous media fluids 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.
