Abstract:In reservoir, the macro-parameters are the macro-reflection of micro-parameters. Network model is established according to the matching of micro-parameters including porosity, permeability and relative permeability. Based on network modeling, the influences of microscopic parameters such as pore-throat radius, homogeneity coefficient of throat radius, pore-throat radius aspect ratio, wettability, pore-throat shape and coordination number on macro-parameters such as porosity, absolute permeability and relative permeability are discussed. On the basis of the sensitivity analysis, the significant influential micro-parameters are determined.
Keywords:network simulation  reservoir parameter  macroscopic parameter  microscopic parameter  influential factor
