ABSTRACT: Moliqing basin is a continental sedimentary basin in the northeast of China, between Changchun and Jilin. The source rocks characterization was done using the data of three wells to define the generative potential, kerogen type and thermal maturity. Basin Mod software was used for the models. The three Eocene source rock formations in the basin are Shuangyang, Sheling and Yongji. Shuangyang is the most important due to its quantity and maturity levels of kerogen with very good generative potential (TOC between 2% - 4%) towards the southern region of the basin. According to the Tmax values, all three source rocks reached the mature stage, and the levels increased from early mature for the Yongji formation, to late mature for some locations of the Shuangyang formation. The 1D and 2D modeling reconstructed shows that the heat flow developed in the basin laid between 64 and 78.1 mW/m2 and had maximum heat flow location towards the center of the basin.
