吐哈盆地是一个聚煤而又富含油气的盆地，己发现了一系列侏罗系煤成烃油气田。中、下侏罗统煤系地层是主要的烃源岩，这套源岩生成的油气具有显著的姥鲛烷优势、重碳同位素以及富含Ｃ２９甾烷等特征。煤岩作为盆地重要的源岩，有两个成烃高峰期。由于早生早排，早期形成的构造对油气聚集十分有利，而喜马拉雅期形成的构造聚集油条件欠佳。
The Turpan-Hami basin is a coal-rich and hydrocarbon-rich basin that has discovered a series of Jurassic coal-to-gas reservoirs. The middle and lower Jurassic coal measures are the major hydrocarbon source rocks. The hydrocarbons generated from these source rocks have the characteristics of pristane, heavy carbon isotope and rich C29 sterane. As an important source rock of the basin, coal rock has two hydrocarbon generation peak periods. Because of the early early Paleozoic, the early tectonic structures are very favorable for hydrocarbon accumulation, while the structural oil accumulation formed in the Himalayan period is not good.
