中国地震沉积学研究现状和发展思考*

地震沉积学是地震地层学和层序地层学的延续发展。最近10多年来,地震沉积学研究受到人们的高度重视,在地震沉积学理论、陆相碎屑沉积砂体、海相沉积砂体、碳酸盐岩和混积岩刻画、地震成岩相预测、砂体精细表征和开发地质应用、地球物理新方法新技术、RGB(Red-Green-Blue)地震属性融合、储集层预测技术以及三维可视化技术雕刻地质体等10个方面取得了长足进展。未来地震沉积学应该关注地震地貌学理论模型、地震岩性学新方法、勘探地震沉积学、开发地震沉积学、地球物理反演新方法和人工智能技术等方面的研究,不断完善地震沉积学理论方法,拓展地震沉积学在油气勘探开发等领域的应用,助力油气勘探开发提高经济效益。

Research status and thoughts on the development of seismic sedimentology in China

The seismic sedimentology is a continuous development of seismic stratigraphy and sequence stratigraphy,and has been paid much attention in recent ten years,especially in its principle,continental and marine classic sedimentary sandbodies,carbonate and mixed deposits,prediction of seismic diagenetic facies,fine characterization of sandbodies,new geophysical methods and techniques,RGB fusion of seismic attributes,and 3D visualization carving geobodies,etc. The future development of seismic sedimentology should concentrate on seismic geomorphological model,new method of seismic lithology,seismic sedimentology for exploration and exploitation, geophysical inversion methods,and artificial intelligent technology,etc. The gradually improvement of theory and methods in seismic sedimentology as well as the extended application of seismic sedimentology in hydrocarbon exploration and exploitation will increase its economic efficiency.
