Contrast Analysis of Geological Conditions between Central and Western Chuxiong Basin and Sichuan Basin

详细信息   
摘要


    

The similarities and differences of basin properties, sedimentary succession and geological condition of oil and gas between Chuxiong Basin and Sichuan 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 such as low porous, tight penetration, high water saturation and strong anisotropism in oil reservoir of Jurassic system. The fissures were very important for the enrichment and large-capacity in the area.
