Abstract：Previous research work was mainly focused on central-eastern Heshituoluogai Basin, and there was almost no exploration work in the western part. Through the field geological survey, sample collection, test and analysis work, the source rocks characteristics and exploration potential of Heshituoluogai Basin were evaluated. The results show that three source rocks were developed in this basin, Devonian, Carboniferous and Jurassic. Jurassic is the main hydrocarbon source rock in the basin, followed by Devonian and Carboniferous source rocks. Comprehensive oil geological condition analysis shows that Heshituoluogai Basin has certain potential, and the Baiyanghe Sag and south slope are favorable exploration areas, which can provide some instructions and basis for next exporation.
