| 摘 要： | 目的探讨纯西辉长岩-变质岩油藏的形成演化过程。方法在查明纯西辉长岩活动时间及其高温、高压持续时间的基础上,结合纯西地区的构造发育史、周围洼陷的生烃史及油气分布规律,对其周围烃源岩的岩性、岩相及有机地球化学等进行了分析。结果建立了纯西辉长岩-变质岩组合油藏的成藏模式。结论辉长岩不仅大大促进了周围烃源岩的生烃、排烃过程,而且将其改造成为变质岩储层,并最终形成了特殊的辉长岩-变质岩组合油藏。

| Abstract: | Aim To analyzze the lithology,lithofacies and organic geochemistry on the source rocks surroundings Chunxi gabbros.Methods It was found that the gabbros not only made the source rocks hydrocarbon generating and ejecting,and also made it become special oil storing stratum,forming a gabbros-metamorphic rocks combined reservoir.Results On the basis of making sure the gabbros activating,its high temperature and pressure standing time,the structural growth history at Chunxi areas and the hydrocarbon generation history of the around sags as well as oil distributing were combined.Conclusion The combined reservoirs' forming process was discussed.In the end,a mode of the combined reservoir was founded. |
