摘　　要：塔里木盆地发育寒武—奥陶系、石炭—二叠系和三叠—侏罗系三套烃源岩系 ,油气资源丰富 ,其中天然气资源量为 92 870× 10 8m3 。从已有天然气勘探成果看 ,探明地质储量为 5 6 18.2× 10 8m3 ,探明率仅为 6 .0 5 % ,加上近期克拉 2、迪那 2和库 1井等气田或含气构造的发现和探明 ,显示出塔里木盆地天然气勘探的巨大潜力。中石化在塔里木盆地拥有登记区块 36个、勘探面积 14 370 1.4km2 ,根据油气地质条件、勘探程度及风险评价等多种因素综合分析 ,天然气勘探的有利方向及领域为阿克库勒凸起东南翼、雅克拉断凸大尤都斯—亚肯构造带。In Talimu Basin there are three series of source rocks, i. e. Ordovician, Carboniferous - Permian and Triassic - Jurassic, with gas resources of 9 287 × 109m3. According to the natural gas exploration results achieved, it is shown that its proved geological reserves are 561.82 × 109m3, so that the proved ratio is only 6. 05 % and the gas fields or gas-bearing structures as wells Kela - 2, Dina - 2 and Ku - 1, etc., have been found and proved, thus revealing a large gas exploration potential in Talimu Basin. There are 36 registered tracts with an area of 143 701.4 km2 controlled by Sinopec in Talimu Basin. According to a comprehensive analysis of various factors as petroleum geological conditions, the degree of exploration, and risk assessment, it is thought that the favourable gas exploration trends should be concentrated at the southeast limb of Akekule Arch, the Dayoudusi - Yaken Structural Belt of Yakela Fault-Arch, the Manan Fault-Fold Belt of Maigaiti Slope and the Kongquehe Slope.
