| 摘 要： | 从吐哈盆地与美国波德河盆地煤层气成藏对比分析入手，分析了波德河盆地低煤阶煤层气勘探成功的原因:高渗煤层中实际含气量大于测试含气量。结合吐哈盆地的优势,提出吐哈盆地的煤层气勘探应当游离气、吸附气兼顾并重;同时对3个重点区块进行了评价,优选出跃1井区块。

| Abstract: | The correlation of coal-bed gas accumulations between Tuha basin and Powder River basin is made. The reason for successful exploration of coal-bed gas with low coal rank in Powder River basin is that the real gas concentration in the high-permeable coal bed is much higher than measured gas concentration. According to superior conditions in Tuha basin, both free gas and adsorbed gas should be highlighted during its coal-bed prospecting. Meanwhile, the evaluation of three major blocks is made, and Y-1 Wellblock is ascertained to be the most favorable target among them. |

| Keywords: | Tuha basin low coal rank coal-bed gas exploration prospect |
