VL，Langmuir volume；PL，Langmuir pressure.
Isothermal adsorption experiments were conducted on sampled shales，and adsorbed gas content were calculated based on the initial reservoir pressure（Table 6）.The adsorbed gas content varies between 0.2 and 2.0 m3/t，and is 0.67 m3/t on average.Furthermore，the gas content shows a positive relationship with TOC value（Fig.11），mainly of two reasons:（1）the higher TOC values generally mean higher gas generation potential；and（2）thekerogen is generally of largely developed micropores which means higher adsorption ability to gas；meantime gas hydrocarbons are easily dissolved in the amorphous and unstructured matrix asphalts.Thus，higher TOC value generally means higher gas generation potential and adsorption ability.
