| 摘 要： | 根据煤层气含量，鄂尔多斯盆地东缘可划分为北部低含气量区，中部高含气量区和南部中含气量区。影响煤层气含 的主要地质因素为煤层埋藏深度，煤的变质程度、地质构造、煤层厚度，顶底板岩性及岩浆活动等。中部高含气量区是最有利的煤层气勘探目标区。

| Abstract: | Based on the content of coalbed methane,the paper divided the eastern margin of Ordos basin into three regions: the northern region with low gas content,the middle region with high gas content and the southern region with middle gas content.Then,the major geological factors affecting the content of coalbed methane were discussed, including burial depth of coal seams,metamorphic degree, geological structures, coal thickness, roof and floor lithologies, and magma activity. Lastly, it is pointed out that the middle region with high gas content is the most favourable target for exploration of coalbed methane. |
