| 摘 要： | 根据莘县凹陷下第三系生油岩的发育特征和地球化学特征。对凹陷内下第三系生油问题进行了探讨.指出沙三中下段是本区主力生油层,其有机质的丰度和类型.可与好生油凹陷相媲美.但由于生油层埋藏较浅,地温梯度偏低,致使各生油层有机质的成熟度明显比好生油凹陷低,主要生油层目前仍处于低成熟—成熟演化阶段.主要油源区集中在禹城、梁水镇等深洼陷区,它们控制着下第三系油气最有远景地区的分布.

| Abstract: | The conditions of petroleum generation of the lower tertiary source rocks in the Shenxian depression were studied on the basis of their lithological and geochemical characteristics. The lower-middle member of sha 3 is the most important source rock bed in the sag. The abundance and type of organic matter in the main source rock are comparable with the best ones in the Bohai Gulf Basin. But the level of maturity of organic matter in the source rocks is obviously lower, because the lower tertiary source beds are of shallower burial and smaller geothermal gradient. The organic matter in the main source bed is still in the early and middle stages of thermal maturation. Yucheng and Liangshuizhen sub-sags are the two major petroleum source areas, which control the distribution of petroleum prospects. |
