摘要: 本文系统分析了吐哈盆地侏罗纪煤系源岩的芳烃分布特征。结果表明，吐哈盆地煤成油形成于特殊成煤环境，其有机质主要来源于高等植物，但也有藻类等低等水生生物的重要贡献，沉积环境主要为湖泊—沼泽相，淡水—半咸水介质，弱还原—还原环境。Abstract: The distribution characteristics of the aromatic hydrocarbons of Jurassic coal-measures sourrocksfrom the Turpan-Hami basin were been systematically studied in this paper. The results indicated thatoiler enerati ng cowls from the Turpan-Hamibasin had been formed in special sedimentary environmentsof coal-measures. The organic matter of coal-measures source rocks mainly came from higher plants,partly from lower aquatic living things, such as algae. The sedimentary environments of the co al-m ca-cures were mainly lake-marsh fades, freshwater emisalt water, weakty reducing-reducing environ-menu.
