【摘要】 地震沉积学是基于高精度三维地震资料、现代沉积环境、露头和钻井岩心资料建立的沉积环境模式的联合反馈,是用以识别沉积单元的三维几何形态、内部结构和沉积过程的一种新的方法、技术体系.地震岩性学与地震地貌学是地震沉积学的核心组成部分,前者研究的方法、技术主要包括:测井约束反演、90°相位转换等,后者主要包括:基于沉积模型的地震正演模拟、地层切片、属性分析、频域滤波和分频解释等,这些技术已经广泛应用在沉积体分析、沉积过程分析、定量储层表征上,并取得了良好的效果.更多还原

【Abstract】 Seismic sedimentology is a new methodology and technology system,a kind of joint feedback on the depositional environment model set up fundamentally on high-precision seismic data,the modern depositional environment,outcrops and cores to identify 3D geometry,the internal structure and deposition process of the sedimentary units.Seismic lithology and seismic geomorphology are key components of seismic sedimentology.The methodology and technology of the former study mainly includes:logging constrained inversion,the 90°phase shift of seismic data etc,the latter includes:seismic forward modelling based on deposition model,stratal slicing,attribute analysis,and frequency decomposing,all of which have been widely applied to sediment body analysis,threedimensional depositional process analysis and quantitative reservoir characterization,and,good results have been produced.更多还原
