摘要：

A network method is presented for the simulation of mercury intrusion and the calculation of the absolute permeability of porous media. The method is specifically applied to a single sample of outcrop sandstone, but can be used for any porous medium. A network is derived in which the mercury intrusion curve, porosity, connectivity, and pore/throat size correlation all agree with experiment. Combinations of the Darcy and Poiseuille equations of flow are used to generate terms expressing the flow capacity of each pore-throat-pore connection (arc). From the overall capacity of the network, calculated by means of a network analysis algorithm, is derived the absolute gas permeability of the sandstone sample which also agrees closely with experiment. The modelling of a range of properties without the use of property-independent fitting parameters provides the basis for a new tool in the analysis and correlation of the pore-level properties of porous media.
