%X 基于松辽盆地西部斜坡区嫩江组8个烃源岩抽提物中芳烃馏分的气相色谱–质谱(GC-MS)分析，结果表明：研究区嫩江组烃源岩中检测到指示陆源高等植物来源的化合物，包括1,2,5-三甲基萘、卡达烯、惹烯、联苯、蒽及苝等，以及表征低等生物来源的？和苯并藿烷等化合物，说明研究区嫩江组烃源岩有机质来源于陆源高等植物和低等生物的双重贡献。三芴系列和苝系列的综合分析表明：研究区嫩江组烃源岩形成于弱氧化的湖相环境。芳烃化合物成熟度参数，如烷基菲系列参数(MPI1)、烷基萘系列参数(DNR、TNR、TMNr、TeMNr)、三芳甾烷系列参数[C<sub>28</sub>-20S/(20S + 20R)-TAS]、苯并藿烷分布特征、二苯并噻吩系列参数(MDR、Rc<sub>4</sub>、Rc<sub>5</sub>)以及脱羟基维生素E系列参数(β-MTTC/γ-MTTC)，指示研究区嫩江组烃源岩主体处于低成熟–成熟阶段。<br />
Based on the GC-MS analysis of the aromatics in the extracts from 8 source rock samples of Nenjiang Formation in the western slope area of the Songliao Basin, the results show that the compounds indicating the source of terrestrial higher plants were detected, including 1,2,5-trimethyl- naphthalene, kardacene, linene, biphenyl, anthracene and perylene, etc. Characterization of the source of lower organisms chrysene and chemical compounds such as benzene and hopane were detected, showing that hydrocarbon source rocks of the Nenjiang Formation in the study area mainly derived from both terrestrial higher plant and lower organisms. The comprehensive analysis of the three fluorene series and perylene series shows that the source rocks of Nenjiang Formation in the study area are formed in a weakly oxidized lacustrine environment. Aromatics maturity parameters, such as alkylphenanthrene (MPI1), alkylnaphthalene (DNR, TNR, TMNr, TeMNr), triarysterane [C<sub>28</sub>-20S/(20S + 20R)-TAS], benzohopane distribution, dibenzothiophene series parameters (MDR, Rc<sub>4</sub>, Rc<sub>5</sub>) and dehydrocopherol vitamin E series parameters (β-mttc/γ-mttc), indicating that the maturity of the main source rocks from the Nenjiang Formation in the study area is in the low-mature-mature stage.
