摘　　要：有机岩石学镜下鉴定和扫描电子显微镜资料表明，准噶尔盆地西北缘具有多层位生油的特征。上二叠统风城组泥岩显微组分中无定形体丰富，具极强的生油能力；上二叠统乌尔禾组及下石炭统烃源岩有机组分以混合偏腐泥型有机质为主；下二叠统佳木河组泥岩为偏腐泥型生油岩。Data from organic petrographic micrcopic identification and SEM indicated that multiple source rocks exist innorthwestern margin of Junggar basin. Amorphous masses are enriched in maceral of Later Permian Fengcheng For-mation shales, with high oil-generating potential. The organic components of Upper Permian Wuerhe Formation andLower Carbohiferous hydrocarbon souree rocks are dOminated by II-towards-sapropel type organic matters, whereasLower Permian Jiamuhe Formation shales are sapropel-prone source rock.
