Abstract: Using the two-phase flow model in multi-pore media, the convective transport model betWeen the fluids of different mineralization intensity and Archie equation, this paper calculates the radial distribution characteristics of resistivity and saturation on the mud filtrate invaded proiile. It is of great importance to the study of resistivity well-logging response.

Key words: Drilling fluid filtrate, Formation damage, Formation water resistivity, Permeability, Filtrate
