Abstract Shale evaluation is an important part of oil-gas geochemistry research and the basis for understanding potential of oil-gas resources. Taking the shale in the first member of Qingshankou Formation in JYY1 well in Changling Sag as object, the paper evaluates the heterogeneity on the basis of organic characteristics and well logging curves. It is considered that the shale mainly belongs to Types I and II of kerogens, in low mature-mature stage. The characterization model of reservoir heterogeneity and grading evaluation of shale show that the dark shale in the first member of Qingshankou Formation is mainly Level-II resource, partly Level-I and a little Level-III, and the overall resource level of source rocks in the upper member is better than that in the lower member of Qingshankou Formation.

Key words： Changling Sag first member of Qingshankou Formation geochemical characteristics heterogeneity shale
