摘要
Based on summaries of previous analyses of evaluation standard of mudstone caprocks, it was analyzed in this paper the conventional physical parameters of mudstone samples from marine carbonate area in South China. It was concluded that the conventional physical parameters could not accurately evaluate the seal capability of mudstone caprocks. A new template to evaluate seal capability combining specific surface area and breakthrough pressure was proposed, providing relatively objective evaluation for seal capability of caprocks.
