摘要

This article presents a multiple-phase numerical simulation model based on a new percolation method called the mutative permeability effect in low-permeability reservoirs and the method to solve those equations is given. Oilfield data are applied to analyze and compare three different percolation patterns. The results of simulating a horizontal well show that the values obtained from the new method are between that of the traditional start-up pressure gradient pattern method and Darcy's method and the data of relative deviation are significant. The new method can provide a more reasonable approach to the seepage characteristics of low-permeability reservoirs.
