摘　　要：本文通过对江西省乐平地区煤储层发育展布、煤层埋深、煤岩特征、煤层含气量、变质程度和顶底板岩性特征分析,认为研究区构造有利于煤层气保存,发育多套煤层,平面上煤层展布较稳定,含气量总体较好,埋深适中,盖层较好,总体煤储层条件较好,具有一定煤层气勘探潜力。安源组煤层是研究区煤层气勘探重点层系。Based on the analysis of coal reservoir development,buried depth of coal seam,coal-rock characteristics,gas content,metamorphic degree and top-bottom slate characteristics in Leping Area of Jiangxi province,this paper concludes that the structure of the study area is beneficial to the preservation of CBM with development of multiple coal seams,the spread of coal seams on the plane is more stable with relatively high gas content,the buried depth is moderate with good cover layer,and the overall condition of CBM reservoir is favorable with exploration potential.The coal seams of Anyuan Formation are the key stratum for CBM exploration in the study area.
