The potential evaluation of source rocks is important for the oil and gas exploration��especially for the lithologic reservoir exploration��and should be considered many factors�� Limited by the actual conditions of Ta'nan sag��the authors choose five indicators including hydrocarbon source rock thickness��organic carbon content�� kerogen type��pyrolysis index and organic matter maturity��to evaluate the characteristics and hydrocarbon generation potential of source rocks in Early Cretaceous Tongbomiao-��Nantun-and Damoguaihe formations�� The study of indicators show that the source rock characteristics are good in general for the studied area��in which the Nantun Formation is the best for source rocks��followed by the Damoguaihe Formaiton��and Tongbomiao Formation which is the worst�� By the means of " direct multiplication" ��the authors comprehensively queued the nine sub-layers in this area according to the hydrocarbon generation potential of source rocks��the best source rocks developed in the SQ3-3 sub-layer in Nantun Formation and the worst source rocks developed in I oil group in Tongbomiao Formation�� In sequence of the hydrocarbon generation potential of source rocks from best to worst is the SQ3-3��SQ3-2��SQ3-5�� SQ3-1��SQ3-4��SQ4-1��II oil group��SQ4-2 and I oil group��
