川西坳陷富有机质页岩孔隙特征
Organic rich shale pore characteristics of Western Sichuan Depression
摘要
Abstract
The pOre characteristics Of the Organic rich shale in Western Sichuan DepressiOn were studied by using lOw temper-ature nitrOgen adsOrptiOn methOd and field emissiOn scanning electrOn micrOscOpy. The results shOw that the surface area Of Organic rich shale in Western Sichuan DepressiOn ranges frOm 3. 404 m2/g tO l9. 473 m2/g, which is far mOre than that Of cOnventiOnal reservOir. The surface area Of shale is mainly prOvided by micrOpOre and transitiOn pOre. The shale develOps a series Of cOntinuOus pOrOsity frOm micrOpOre tO mesOpOrOus. The average pOre diameter ranges frOm 3. 06 nm tO 7. 82 nm. The pOre types are mainly parallel-plate pOre and blind pOre, which is clOsed at One end with certain amOunts Of ink-bOttle pOre at the same time. The surface area Of shale and cOntent Of Organic carbOn fOrm pOsitive cOrrelatiOn. The cOntent Of Organic car-bOn and degree Of thermal evOlutiOn are negatively cOrrelated with aperture. Lastly fragile mineral such as quartz is weak pOsi-tively cOrrelated with surface area.关键词
