Scaling laws in network models: porous medium property prediction during morphological evolution

摘要

A 3-D network model was used to represent a porous medium and the macroscopic properities of the network (like permeability)were simulated by Monte Carlo method. It was shown that these macroscopic proprties can be relatd to network parameters(throat-size distribution parameters, network size and connectivity) through power law correlations , as can be inferred from percolation theory. In this way, macroscopic proprties evaluation during the morphological evolution of a 3-D network requires less computational effort, which facilitates the incorporation of this model oil flow simulators
