| 摘 要： | 地震沉积学是在地震地层学和层序地层学基础上发展起来的、沉积地质学与地球物理学相互交叉的新兴学科,在刻画薄层砂体、表征储集层和预测岩性圈闭等方面发挥了重要作用。在表述地震沉积学发展简史的基础上,介绍了地震沉积学的基本概念、基本原理和主要研究流程;在建立精细层序地层格架基础上,重点阐述了90°相移、分频处理与频谱分解、属性优选、地层切片、地球物理反演、地震岩性解释和RGB(红色、绿色、蓝色)地震属性融合等地震沉积学关键技术以及地震沉积相实例分析。认为中国地震沉积学应该围绕不同类型沉积盆地开展油气勘探阶段地震地貌学(地震沉积相模式)和复杂(多样)地震岩性学综合研究,在油气开发阶段,充分利用RGB地震属性融合等多种地球物理方法技术,开展多种成因类型砂体构型和储集层定量表征研究。综合研究表明,地震沉积学是沉积地质学发展的新航程。

| Abstract: | Seismic sedimentology is an emerging interdisciplinary subject between sedimentary geology and geophysics developed on the basis of seismic stratigraphy and sequence stratigraphy,which exerts a great influence on delineation of thin-bed sand-bodies,reservoir characterization,prediction of lithographic traps. The fundamental concepts,principles and main work-flows of seismic sedimentology have been well introduced based on its brief development history,several critical technologies regarding seismic sedimentology namely as 90°phase shift,frequency division processing,spectrum decomposition,attribute optimization,stratal slicing,geophysical inversion,seismic lithological interpretation,and RGB blending of seismic attributes as well as case study of seismic sedimentary facies have been well clarified within detailed sequence stratigraphic frameworks. Discussion shows that seismic geomorphological(seismic sedimentary facies model)and complicated seismic lithological study during the stage of hydrocarbon exploration should be conducted in sedimentary basins with various type when concerning seismic sedimentology in China,and the architecture of sand-bodies with different genesis and quantitative reservoir characterization are well implemented with RGB blending of seismic attributes and many other geophysical technologies during the stage of hydrocarbon exploitation,which will be the new development trend of sedimentary geology. |
