摘　　要：采用地球化学和盆地模拟技术相结合的方法 ,研究了松辽盆地北部葡深 1井深层烃源岩的地球化学特征 ,内容包括有机质的丰度、类型以及有机质热演化特征。利用盆地模拟技术模拟烃源岩各地质时期的热演化阶段。结果表明 ,葡深 1井下白垩统的登娄库组、营城组、沙河子组均发育有暗色泥岩 ,有机质丰度为中—差 ,有机质类型较差 ,有机质成熟度较高 (多处于高—过成熟状态 )。综合认为生油潜力较差 ,以生气为主。This paper combines geochemistry and basin simulation technique to study the geochemical characteristic of the deep hydrocarbon source rock of Well Pushen 1 in the north part of Songliao Basin. It uses basin simulation technique to simulate the heat evolution stages of various geologic period of hydrocarbon source rock. The result shows that Denglouku, Yingcheng and Shahezi members in Lower Cretaceous in Well Pushen 1 develop with dark mudstone, organic matter richness is middle poor, organic matter type is poor and organic matter maturity is high. The oil generation potential is poor, mainly generating gas.
