Abstract: Based on the plane model of pore-throat of sandstone and pore diameter, throat width and percentage pore area from image processing of scanning electric microscope(SEM), apparent permeability formula for characterizing sandstone reservoir quali ty was derived.The calculation were correlates well with true permeability.
