运用煤层气地质学原理和钻孔资料，分析呼鲁斯太矿区煤层气成藏条件。研究发现，矿区煤层发育良好、厚度大且稳定、镜质组含量较高，具有较强生烃能力；煤层埋深适中，以焦煤、肥煤为主，割理较发育，有利于煤层气解吸；矿区内多发育逆断层、断层面密闭，煤层顶底板多为页岩、砂质泥岩、灰岩，水文地质条件简单，水力联系微弱，保存条件较好，具有良好成藏条件。

Geology principles and drilling data of coalbed methane (CBM) were used to analyze CBM accumulation condition in Hulstai coal district. The results show that coal seam is well developed, thick, and stable, with high vitrinite content and hydrocarbon-generation potential. The coal seam mainly consists of coking coal and fat coal at suitable burial depth. The developed cleat is beneficial for CBM desorption. Mining area develops many reverse faults with closed fault surface. Roof and floor of the seams are mainly shale, silty mudstone, and limestone. The simple hydra-geological condition leads to weak hydraulic connection, ideal conservative condition, and better accumulation condition.
