楚雄盆地与四川盆地中西部地质条件对比分析

通过楚雄盆地与四川盆地中西部区域地质条件和油气地质条件的对比研究,探讨了楚雄盆地与四川盆地中西部地区盆地性质、沉积序列、油气地质条件等方面的异同点,从而给楚雄盆地的油气勘探一些启示：它们间的基本地质特征、油气地质特征类似,且上三叠统地层为主要的烃源岩和自生自储组合,侏罗系储层也具有低孔、低渗、高含水饱和度、非均质性强的特征,裂缝对油气的富集、高产起到了重要作用。认为：加强砂体的展布、连通性研究,裂缝、断层性质、形态、沟通性、规模等研究,在有白垩系、第三系覆盖区完全有可能进行油气勘探。

Contrast analysis of geological conditions between central and west Chuxiong basin and Sichuan basin

The similarities and differences of basin properties,sedimentary succession and geological condition of oil and gas between Chuxiong basin and Sichun basin were discussed through contrast study of regional geological conditions and oil-gas geological conditions.The studies revealed that there were similar basic geological characters and oil-gas geological characters;Upper Triassic series could be considered as main hydrocarbon source bed,source bed and oil reservoir assemblage;There were obvious characters ...
