目前在综合研究岩石的物理机械性质时确定岩石的孔隙度和渗透率是必要的。孔隙度的大小是单位体积岩石中孔隙的数量特征和统计数据,渗透率是确定气流通过孔隙介质的渗滤能力。显然,一般地看来渗透率决定于有效孔隙度的大小和孔隙空间的结构。 现代文献中企图根据岩石的孔隙特征计算岩石的渗透率。从水动力学观点来看水流通过某些导管可以是紊流,层流和絮流(在微毛细管内)。这说明了在分析通过天然孔隙介质——岩石的渗滤作用时这些规律是可以应用的。
At present, it is necessary to determine the porosity and permeability of the rock when comprehensively studying the physical and mechanical properties of the rock. The size of the porosity is the number of pores per unit volume of the rock characteristics and statistics, permeability is to determine the air flow through the porous media percolation ability. Obviously, permeability generally depends on the size of the effective porosity and the structure of the pore space. Modern literature seeks to calculate rock permeability based on the pore characteristics of rocks. Flow through some conduits from a hydrodynamic point of view can be turbulent, laminar and flocculent (within microcapillaries). This shows that these laws are applicable when analyzing the percolation of rock through the natural pore media.
