通过伊犁盆地伊宁凹陷侏罗系煤系地层有机质丰度、类型研究与对比，揭示出伊宁凹陷侏罗系煤系地层生烃特征：八道湾组煤系地层是伊宁凹陷侏罗系主要生烃层系，西山窑及三工河组对生烃的贡献甚微。伊宁凹陷侏罗系煤岩和泥岩有机质主要以高等植物输入为主，属较典型成煤沉积环境产物。通过热演化程度的分析与对比，反映出伊宁凹陷侏罗系热演化程度（Ｒｏ分布在０．４％～０．７％之间）较周围侏罗系盆地低，未达到生烃高峰期，有机质向烃类转化量有限。显微组分及活化能分析与对比结果表明，伊宁凹陷侏罗系烃源岩缺乏早期生烃组分，早生早排的生烃量有限
Through the study and comparison of organic matter abundances and types in the Jurassic coal measures strata in the Yining Sag, Yili Sag, the hydrocarbon generation characteristics of the Jurassic coal measures in the Yining Sag are revealed. The coal measure strata of the Badaowan Formation are mainly Jurassic in the Yining Sag The hydrocarbon generation strata, Xishanyao and Sangonghe formation contribute little to hydrocarbon generation. The organic matter of Jurassic coal and mudstone in Yining Depression is mainly dominated by higher plants, which is a typical product of coal-forming sedimentary environment. Through the analysis and comparison of the degree of thermal evolution, it shows that the Jurassic thermal evolution degree (Ro between 0.4% and 0.7%) in the Yining Depression is lower than that in the surrounding Jurassic basin and does not reach the peak of hydrocarbon generation , The conversion of organic matter to hydrocarbons is limited. Analysis and comparison of the microstructure and activation energy shows that the Jurassic source rocks in the Yining sag lacks early hydrocarbon generation,
