Reservoir Numerical Simulation Study Based on Formation Parameters’ Time-Variability

AbstractA novel simulation function is added into a reservoir simulator to consider the reservoir parameters’ variation by defining the variation pattern of reservoir porosity, permeability and relative permeability in water flooding. It indicates that considering the variation of porosity and permeability causes the increase of reservoir heterogeneity and thus the decrease of predicted oil recovery. In actual reservoir development, the influence of permeability's variation on oilfield development rules is stronger than that of porosity
