The analysis of influence factors and mechanism of shale gas adsorption is a basic theory about high efficiency development of shale gas.In this paper,based on volumetric methane adsorption isotherm experiments,using selected shale samples,a series of adsorption isotherms under different temperature,pressure,particle size,moisture were obtained on different samples.The characteristics of the adsorption isotherms were analyzed and the adsorption rules were compared to the Langmuir equation.And the phenomenon and mechanism about bending of methane adsorption isotherm for shale were analyzed particularly.The findings indicate that,for low TOC shale,there were differences between the obtained adsorption isotherms and standard type Ⅰ IUPAC adsorption isotherms,and the adsorption was not in accordance with the Langmuir equation absolutely.At different temperature and particle size of shale sample,differences between the isotherms and standard type Ⅰ adsorption isotherms were absolute.The sample moisture has an enormous effect on adsorption capacity of shale to methane.The bending of adsorption isotherms for shale to methane may occur while pressure was at critical pressure of methane or so.The reasons for this may be experimental error,heterogeneity of shale,matrix swelling and the absence of adsorption phase.
Key words: Shale gas; Adsorption; Adsorption isotherm; Langmuir equation; Critical pressure; TOC
