摘　　要：松辽盆地东岭区块烃源岩抽提物具有饱和烃质量分数大、非烃+沥青质质量分数小、碳同位素较轻的特征。利用GC/MS技术对烃源岩抽提物分析,结果为:饱和烃馏分中C29甾烷立体异构体比值、三降藿烷Ts/Tm比值、C31藿烷22S/(22S+22R)表明东岭区块烃源岩达到热演化平衡值。芳烃馏分的色谱分布特征、甲基菲指数、4-/1-MDBT和2,4-/1,4-DMDBT比值等参数都表明泉头组烃源岩处于中等成熟度,营城组和上侏罗统火石岭组烃源岩处于较高成熟度。Extracts of source rocks are of characteristics of high content of saturated hydrocarbons, low content of non-hydrocarbon and asphahene, and light carbon isotope in Dangling Area of Songliao Basin. The maturity parameters of saturated hydrocarbon coming from the GC-MS analysis results, such as the isomer ratio of C29 sterane, the ratio of trisnorhopane Ts/ Tm and C31 22S/（22S＋22R）, show that the source rocks reached thermal maturity stage, in Dongling Area. The distribution characteristics of aromatic chromatography, MPI, the ratios of 4-/1-MDBT and 2,4-/1,4-DMDBT, all of those maturity parameters suggest that the Quantou Group should lie in middle maturity stage, whereas the Yingcheng Group and the Huoshiling Group of Upper Jurassic reached high maturity stage.
