摘　　要：结合不同次级向斜13个煤样的等温吸附解吸实验以及比德—三塘盆地多煤层区两口煤层气试井资料,分析了不同含气系统内煤储层吸附解吸特征,研究了含气系统类型与多煤层区煤层吸附解吸特征的相关性。研究表明:在多煤层条件下,影响煤吸附解吸特征的主控因素并非不同的含气系统类型,而仍然为储层条件及煤质。In combination with isothermal adsorption and desorption experiments with different secondary syncline 13 coal samples and the logging information of two coal bed methane wells in the multi seam region of Bide Santang Basin, the paper analyzed the adsorption and desorption features of the coal seam in different gas beating system and studied the correlation of the adsorption and desorption features for the seams in gas beating system type and the multi seam region. The study showed that, under the multi seam conditions, the main control factors affected to the coal adsorption and desorption features would not be different gas beating system type and still would be the seam conditions and coal ctuality.
