Abstract

Abstract: Smectite-rich sandstone is characterized by water swelling and high-temperature dehydration and contraction. Its porosity and permeability measured by core sampling, wash oil and dry sample tend to being higher than the real values. For this reason, this paper proposes a correction method for acquiring real porosity and permeability of smectite-rich sandstone. The corrected values can get rid of these situations above mentioned.

Key words: smectite, porosity, permeability, correction coefficient
