摘要: 自从美国在低煤阶的粉河盆地取得了煤层气勘探突破之后,低煤阶含煤盆地已不再成为煤层气勘探的 “禁区”。据专家估算,我国低阶煤中拥有煤层气资源量约16×1012m3 ,占全国煤层气资源量的47%. 吐哈盆地是我国主要的低煤阶盆地之一,通过对该盆地煤层发育特征、煤层气含量与成分、煤层的等温吸附特征、煤储集层特征等煤层气基本地质特征的研究,指出吐哈盆地具有雄厚的煤层气勘探基础,煤层气资源潜力大,勘探领域广阔,勘探前景看好,将成为吐哈盆地常规油气勘探的一种重要替补类型。

Abstract: Since success of coal-bed gas prospecting in Powder River basin with low coal rank in America, coal-bearing basin with lowcoal rank has been no longer “restricted area” for coal-bed gas exploration. As estimated by experts, China has coal-bed gas resources in low coal rank of about 16x 1012m3,accounting for 47% of the total amount. Turpan-Hami basin is one of major low coal rank basins in China. This paper presents the basinal coal-bed developed feature, coal-bed gas concentration and composition, property of coal-bed isothermal adsorption, as well as coal reservoir characteristics. It is concluded that Turpan-Hami basin is of abundant material bases,wide and bright prospects for coal-bed gas exploration. In the coming future, coal-bed gas is likely to be a major substituted resource for conventional oil and gas prospecting in Turpan-Hami basin.

Key words: Turpan basin, Hami basin, coal, coal-formed gas, resource, exploration
