摘要： 松辽盆地南部长岭地区主要分布有上白垩统嫩江组和青山口组、下白垩统登娄库组和沙河子组-营城组烃源岩。介绍了长岭地区主要烃源岩的分布特征、有机质丰度、类型及热演化程度,描述了烃源岩中有机质族组成特征、饱和烃气相色谱特征、甾烷、三萜烷系列化合物分布特征及稳定碳同位素组成特征等,并根据这些地球化学特征分析了不同层位烃源岩的母质类型、生烃环境及有机质演化规律。

Abstract: There mainly distributes four series of source rocks, including Nenjiang, Qingshankou, Denglouku and Shahezi-Yingcheng formations of Cretaceous in Changling area, Songliao basin. This paper presents the distribution feature of dark mudstone, organic matter content, types and maturity of organic matter in these source rocks mentioned above. The geochemical characteristics of extract from the source rocks, such as organic matter composition of saturation hydrocarbon (based on gas chromatogram), composition and configuration characteristics of steroid and triterpane (based on GC/MS),and carbon isotopes composition of chloroform bitumen A and group composition have been presented too. According to the geochemical characteristics of organic matter in source rocks, the parent matter type, geochemistry environment and maturity of organic matter were analyzed.

Key words: Songliao basin, Changling, source bed, geochemistry, characteristics
