摘要
根据琼东南盆地陵水凹陷三维地震、钻井及岩心资料,对中新统梅山组发育的深水扇特征、沉积模式及控制因素进行了研究,结果表明,梅山组中发育着多种典型重力流构造,沉积物为半深海环境下的重力流沉积;通过对高分辨率三维地震资料的综合分析,结合岩矿特征、粒度分析、沉积构造、测井相等分析,可识别出水道、水道间、席状砂等沉积微相;陵水凹陷梅山组深水扇为陆架边缘三角洲—峡谷(下切谷)—深水扇的沉积模式,其形成受三亚组沉积晚期古构造地貌、相对海平面变化、坡折带及三角洲物源供给能力等多种因素的控制。
The 3D seismic data,drilling and core sample data form Lingshui sag in Qiongdongnan basin are used to study the deep-water fan characteristic,sedimentary pattern and controlling factors developed in the Meishan formation of the Miocene.The results showed that several kinds of gravity-flow structures and sediments are developed in this formation and in bathyal environment.By analyses of 3D seismic data integrated with rock and mineral feature,grain size,sedimentary structure and log facies,such sedimentary microfacies as channel,interchannel and sand sheet can be recognized.The Meishan deep-water fans belong to shelf-margin delta-valley-submarine fan sedimentary model which is mainly controlled by the tectonic framework of the Late Sanya formation,relative sea-level changes,slope break evolution and the material supply of the delta.
