Research on Permeability Upscaling Based on Numerical Rock Core and Geomechanics

Article Preview

Abstract:

Basing on pore structure obtained with CT, Navier-Stokes numerical simulation of fluid flow in the rock core was carried out. The calculated result of the simulation, was further applied in the core permeability determination. To further understand the flow behavior and upscaling mechanism, analysis of pore throat distribution in the core was carried out, and effect of pore structure on upscaling was discussed. Results show that commonly used permeability upscaling method didn’t show good results when pore size varies greatly. Considering this situation, a weighted average method for permeability upscaling is presented which can address this problem.
