Shale gas, with an estimated 214.55 trillion cubic meters of technically recoverable resources globally, plays a vital role in energy structure optimization. Shale gas in the adsorbed state accounts for approximately 20 % to 85 % of the total gas content. The adsorption behavior and underlying mechanisms of shale gas are crucial for the assessment of shale gas reserves [1], [2], [3], [4], [5], [6], [7]. Shale gas reservoir contains abundant water from two primary sources.
