摘要： A method for generating a petrophysical model of a reservoir includes: selecting a depositional environment; modeling a sedimentation process in the depositional environment to produce a pore-scale model of a rock matrix of the reservoir having a lithology and facies of sedimentary rock; validating the pore-scale model using a core sample and/or known geological information to provide a validated pore-scale model; modeling the reservoir with the validated pore-scale model saturated with one or more selected fluids; upscaling one or more physical properties of the validated pore-scale model saturated with the one or more selected fluids to dimensions at which at least one macro-scale property can be measured by a downhole tool to provide an upscaled model having one or more macro-scale properties; and validating the upscaled model using the at least one macro-scale property measured by the downhole tool to provide the petrophysical model of the reservoir.
