摘要

摘要: 基于新采集的高精度三维地震资料,对琼东南盆地南部隆起北缘松南三维台缘礁开展了地震沉积学研究。在识别海平面变化控制下高频礁生长单元构成样式的基础上建立了研究区成礁模型,在此模型指导下利用地震属性技术在体系域内精细刻画台缘礁沉积微相的空间展布特征,并结合速度模型约束下的储层孔隙度反演预测储层物性的分布格局。研究认为,研究区台缘礁的礁体生长具有典型的复杂镶边型特征,体系域约束下层间振幅属性能有效地反映小尺度等时单元内台缘礁生长单元的空间展布特征,孔隙度预测中的地震低速异常区是潜在的有利勘探区。

Abstract: In Songnan 3D area in the northern margin of the southern uplift of the Qiongdongnan Basin,seismic sedimentology has been applied in the studies of platform edge reef based on recent 3D seismic data with high resolution.The style of active generation unit of reef is controlled by the fluctuation of sea level,and based on which a reef generation model has been established.Seismic attribute has been applied to describe the distribution of sedimentary microfacies of platform edge reef.Combined with reservoir porosity inversion restricted by velocity model,the physical property of reservoir can be predicted.Platform edge reef growing in the study area is characterized by complex border.Amplitude features among different layers reveal the spatial distribution of growth unit of platform edge reef in small and equal period.Abnormal low velocity zones in porosity study are potential targets for exploration.This research may provide new ways for reef-hydrocarbon reservoir exploration in the Qiongdongnan Basin.
