Embodiment Construction
[0029] Langmuir model is a commonly used model to describe the methane adsorption isotherm of coal and shale kerogen, and the Langmuir volume V L and Langmuir pressure P L It is the most important parameter to determine the adsorbed gas content.
[0030] A dynamic calculation method for shale adsorbed gas content based on the Langmuir model, the calculation model is:
[0031] Agas = V LT * P P LT + P = F ( T ) * V L 0 * P P LT + P ...
