济阳坳陷晚古生代岩相古地理
|
摘要
通过对本区30多口井系统性沉积相研究认为,济阳坳陷晚古生代自下而上为海相、海陆过渡相和陆相沉积,划分了5种沉积体系:障壁-泻湖-潮坪体系、碳酸盐岩陆棚体系、三角洲体系、泥炭沼泽体系和河流体系。根据岩石类型、颜色、自生矿物、生物化石等特征,进一步将上古生界沉积体系划分为7种沉积相和12种沉积亚相。利用层序地层学方法分层序研究了济阳坳陷晚古生代地震相、沉积相和古地理特征,为评价晚古生代的生、储、盖条件奠定基础。
According to systematic sedimentary research on more than 30 wells of Jiyang depression, Later Paleozoic sedimentary in this area was made of sea facies, transitional facies and continental facies from up to bottom. Later Paleozoic sedimentary system has 5 sedimentary systems: barrier lagoon - tidal flat system, carbonate continental shelf system, delta system, peat swamp system and river system. The sedimentary systems were divided 7 facies and 12 subfacies according to the characteristics in rock types, color, authigene and biological fossil. Based on sequence stratigraphy principles and methods, the study on later Paleozoic seismic facies, sedimentary facies and paleogeographic characteristics in Jiyang sag settles the foundation for evaluating Later Paleozoic oil source bed, reservoir and caprock.
