Key Laboratory Oil Shale and Coexisting Minerals of Jilin Province Changchun China 3. Key Laboratory for Mineralization Exploration and Exploitation of Oil Shale and Paragenetic Energy Minerals Changchun China Abstract Oil shale layers found in Fuyu -Changchunling area are popularly developed in the Upper Cretaceous Qingshankou Formation of Songliao Basin. Most of them present brown and dark grey color with the development of horizontal bedding and massive bedding which indicates their semi-deep to deep lake sedimentary environment. Systemic test and analysis results show that oil shale layers here have the charactertics of moderate calorific value high ash content and low sulfur content with medium oil yields. The TOC content is 4. 87% to % with the average value of 7. 88% which reflects the high organic matter content in the oil shale. The rock-eval analysis jlu. edu. cn

2 results show that the oil shale layers are mainly dominated by type I organic matter and type II organic matter dominated secondly. The T max value of 437 to 449 indicates the immature to low-mature stage of the organic matter in oil shale. The distribution of thickness and oil yield of oil shale layers indicate that the 2nd and 3rd oil shale layers of the target strata both have the maximum thickness and the best continuity. Besides the oil shale layers in boreholes ZK0809 and ZK3201 both have the relatively higher total thickness while in the borehole SY9 the oil shale layers have the highest oil yield.
