摘要
A method for evaluating thickness and density of adsorbed methane in pores contributed by organic matter, clay and other minerals in a mud shale reservoir, including: crushing a sample and selecting three or more subsamples with different meshes to determine TOC, kerogen, whole rock analysis, low-temperature nitrogen adsorption-desorption and methane isotherm adsorption; calculating contents of organic matter in respective subsamples from TOC and kerogen contents; normalizing contents of organic matter, clay and other minerals; evaluating the volume of pores contributed by organic matter, clay and other minerals per unit mass according to contents thereof and low-temperature nitrogen adsorption-desorption; evaluating content of adsorbed methane in organic matter, clay and other minerals per unit mass according to contents thereof and methane isotherm adsorption; and establishing a model for calculating density and thickness of adsorbed methane.
