Abstract/Summary The adsorption isotherms of Bide-Santang Basin's main coal seams is studied based on analyzing two coalbed methane (CBM) wells in Huale exploration region and testing the coal samples. A conclusion has been made that the adsorption capacity of Bide-Santang Basin's main coal seams is high. The Langmuir volume (VL) of dry ash-free basis range from 17.69 m3/t to 21.38 m3/t, and the average is 19.46 m3/t. The methane saturation of the coal reservoir is lower than 100%, ranging from 75.04% to 105.55% commonly, and the average is 84.51%. It indicates that coal reservoir in the research area is undersaturation. The critical desorption pressures are between 1.22MPa and 9.1MPa, and the average is 3.25MPa. The coalbed methane theory recovery rates are between 19.96% and 46.15% with average of 34.51%.
