准噶尔盆地侏罗系烃源岩包括煤沼泽和淡水湖相沉积。煤沼泽沉积物中的生烃显微组分以高等植物源的基质镜质体和壳质体为主。在湖相，显微组分由细菌蚀变的无定形体、藻无定形体、藻质体、壳质体和镜质体组成。盆地南缘齐古油田下侏罗统八道湾组煤和煤质泥岩是油气的主要来源。盆地中部的彩南油田为湖相生油岩。
Jurassic source rocks in the Junggar Basin (NW China) include coal swamp and freshwater lacustrine deposits. Hydrocarbon‐generating macerals in the coal swamp deposits are dominated by desmocollinite and exinite of higher‐plant origin. In lacustrine facies, macerals consists of bacterially‐altered amorphinite, algal‐ amorphinite, alginite, exinite and vitrinite. Coals and coaly mudstones in the Lower Jurassic Badaowan Formation generate oil at the Qigu oilfield on the southern margin of the basin. Lacustrine source rocks generate oil at the Cainan oilfield in the centre of the basin.
