摘要: 地震沉积学是应用三维地震信息研究沉积岩及其形成过程的学科,是继地震地层学、层序地层学之后的又一新兴边缘交叉学科。地震沉积学研究强调地震同相轴并不一定是等时的,它以90°相位转换技术、地层切片技术和分频解释技术为主要研究手段,结合其他地球物理技术进行等时地层格架下的沉积微相研究,在油气勘探与开发中展示出了良好的应用前景。在大港油田滩海关家堡地区油藏评价中,利用地震沉积学原理及方法,基于地震属性分析和井资料进行了沉积微相分析,为油田开发奠定了扎实的基础。另外,地震沉积学方法还可用于构造的精细解释。利用90°相位转换和分频解释技术对秘鲁S油田进行了构造解释,建立了精细的构造模型,发现了新的低幅度构造圈闭目标。

Abstract: Seismic sedimentology is the use of seismic information in the study on sedimentary rocks and their formation processes. It is a new marginal intersection subject following the seismic stratigraphy and sequence stratigraphy. It emphasizes that seismic events don't always follow the isochronal depositional surfaces. The key methods for researching the seismic sedimentology include 90°-phasing convertion, stratal slicing and frequency decomposion. The application of the key techniques combined with other geophysical technologies in the microfacies research under the isochronal strata framework showed the favorable prospect in petroleum exploration and development. The evaluation of reservoir in Guanjiapu area of Dagang Oil Field based on the seismic attributes and well log data analyses using the concept of seismic sedimentology settled a strong base for the development of the field. The structure interpretation of S Oil Field in Peru using the seismic sedimentologic methods was helpful to construct an accurate structural model and find the new low-amplitude traps.

Key words: seismic sedimentology, sedimentary microfacies, structure interpretation, 90? phasing convertion technique, stratal slicing, frequency decomposing technology
