A method and apparatus for determining content of adsorbed gas in a deep shale, and a server, wherein experimental tests are combined with molecular dynamics models. Firstly, tests are performed on a core sample of a target area at various temperatures in a first-class pressure environment with low pressure to obtain shale gas adsorption data of the core sample; next, a first shale molecule dynamics model of the core sample is established, and a fitting adjustment is performed on the first shale molecule dynamics model using the shale gas adsorption data to obtain a second shale molecule dynamics model. Further, the second shale molecular dynamics model is used to obtain, by analogue simulation, shale gas adsorption data of the core sample corresponding to the various temperatures in a second-class pressure environment with high pressure, so as to obtain an accurate and comprehensive adsorption characteristic curve in a full pressure range.
