【摘要】 本文在大量岩石、地层、构造及古生物资料的基础上,以活动论为依据,将准噶尔盆地石炭、二叠系沉积相划分为3个相区、11个相带、13个相,根据大地构造背景,又将它们归纳为6个相系。根据沉积相分布规律及大地构造背景等建立了石炭纪、早二叠世及晚二叠世的沉积体系模式,并阐述了主要生油气层、储油气层及盖层有利相带的分布规律。更多还原

【Abstract】 Based on a lot of petrological ,stratigraphic. tectonic and palaeotological data and using the theory of mobilism asa conceptual guide, this paper has categorized and delineated the carboniferous and permian sedimentary facies inJunggar Basin into three (3) facial areal divisions eleven (11) facial zones and thirteen (13) facies types. Further-more, based on their tectonic backgrounds made them further reducted into six (6) facial series . Sedimentationregime’s patterns had been developed for carboniferous, early and late permian,according to their tectonic backgroundand distributing regularity of sedimentary facies . The destributing regularities of favorable facial zones of principalhydrocarbon generating beds ,hydrocarbon reservoir beds as well as caprock beds also becn stated.更多还原
