摘　　要：在地震沉积学研究中,地层格架的建立是最基础和最重要的工作之一,只有将地层格架精细建立到沉积体系级别的最小地层单元上,进行沉积相研究才有可能得到对实际生产有指导意义的成果。充分运用地震资料和地球物理评价技术对沉积体系内部的岩性及其空间展布进行分析评价,不仅能够指导储层精细研究,而且在隐蔽圈闭勘探中能够发挥决定性的作用。本文提出的地震沉积学应用方法体系在海上某一新区勘探目标评价中进行了应用,其预测结果得到了钻探证实。In the study of seismic sedimentology,establishing a stratigraphic framework is one of the most basic and important procedures,and the sedimentary facies analysis will obtain the results with guiding significance to actual production only if the stratigraphic framework is established to the minimum stratigraphic unit in the level of sedimentary system.The analysis and evaluation of lithology and its spatial distribution within a sedimentary system by comprehensively using seismic data and geophysical evaluation techniques can not only direct the refined reservoir study,but also play a decisive role in the exploration of subtle traps.The application method system of seismic sedimentology proposed in this paper was used in the exploration target evaluation in an offshore new area,and the prediction results have been confirmed by drilling.
