摘　　要：近年来诸多学者对准噶尔盆地乌伦古坳陷展开了大量研究,得出了许多重要的成果,也积累了宝贵的经验,认为乌伦古坳陷具有极大的勘探潜力。但对其主力烃源岩的认识方面,仍然存在很多争议。本文在总结前人研究成果的基础上,进行了大量的基础和实验研究,对乌伦古坳陷侏罗系、三叠系、石炭系烃源岩地球化学特征进行了详细系统的评价,对其生烃潜力进行了预测,认为下石炭统为最优质烃源岩,是主力烃源岩,可以作为后期勘探的主要目的层位,上石炭统巴塔玛依内山组和三叠系白碱滩组次之,侏罗系烃源岩较差认为不具备生烃条件。In recent years, many scholars launched a large number of researches in the Wulungu Depression of the Junggar Basin. Many results and valuable experiences indicate that the Wulungu Depression has great exploration potential. But a lot of controversies still exist in the awareness of the main hydrocarbon source rocks. In this paper,on the basis of summarizing the predecessors ＆ research results,lots of basic and experimental studies are conducted. A detailed evaluation is carried out in the source rock geochemistry characteristics of Jurassic, Triassic and Carboniferous in the Wulungu Depression, and predicted their hydrocarbon generation potential is predicted As the most high-quality hydrocarbon source rocks,the Lower Carboniferous is the main hydrocarbon grnerating member of the depression, and can be explored,as the target layer the Upper Carboniferous and Batamayineishan Formation and the Triassic Baijiantan Formation are followed,and Jurassic source rock is poor and has no raw hydrocarbon conditions.
