【摘要】 在1987—1997年前人对东沙碳酸盐岩台地的综合研究基础上,系统总结前人的研究成果,在取得新的钻井、薄片、地震等资料基础上,运用岩心/薄片鉴定、地震沉积解释等手段,展开沉积相及沉积模式的研究,并将研究成果与前人认识进行比较分析。在建立研究区沉积体系和沉积模式基础上,将笔者的认识与前人成果进行比较,取得如下认识:①碳酸盐岩的岩石学分类方案不同;②沉积相的划分类型和依据略异;③沉积相带发育受层序演化影响明显,不同体系域的沉积模式各不相同。更多还原

【Abstract】 The Miocene Carbonate deposits are widely developed in the Pearl River Basin(East) over an area of about 5 million square kilometers.Reefs were the main targets in the Early stage of exploration.With the progress of geological study,lithological reservoirs have gradually become the major concern of exploration.In mean time,there is still lack of knowledge about the types of carbonate rocks and their distribution.In this paper,upon the basis of new drilling and seismic data,we made a comprehensive study of the previous research products.Our conclusion is slightly different due to the application of different carbonate and sedimentary facies classification systems.Study of sequence evolution indicates that depositional models are different in different system tracts.更多还原
