Abstract

Adsorbed gas content is essential to the calculation of shale gas reserves,and adsorbed gas desorption process is directly related to the production of shale.Isothermal adsorption and desorption experiments under different conditions were carried out with Longmaxi shale samples collected from south of Sichuan and Zhaotong area.The results show that the maximum adsorption volume V_Ldecreases with the increase of temperature and the desorption ratio increases with the increase of temperature,which both showed a good linear relationship with the temperature. TOC and clay mineral content will affect the shale gas adsorption capacity.The shale maximum adsorption volume has a positive correlation with TOC in shale with high TOC content,while the maximum adsorption volume and clay mineral content was positively correlated in shale with low TOC content.The presence of water will reduce the shale adsorption capacity and also the desorption ratio.The remaining adsorption volume after desorption increases with the moisture content.

Key words： Shale gas; Adsorption; Temperature; Moisture content; minerals; TOC
