The article elaborated the seismic sedimentology's concept and the discipline characteristic, thought the earthquake sedimentology may divide into the seismic geomorphology and the reservoir seismography according to the research criterion, propose research method from the application aspects. The article proposed the smallest isochronal strata unit concept at the first time, namely three-phase (seismic, oil well logging, core) unifies the unification when the research the well and seismic, is smallest geology chart unit with depositional analysis.

文章阐述了地震沉积学的概念和学科特点，认为地震沉积学可以按研究尺度分为地震地貌学和储层地震学，从应用角度提出了地震沉积学的研究思路，并首次提出最小等时研究单元的概念，即三相（地震相，测井相，岩芯相）结合研究时井震统一的尺度，是沉积分析时一个最小的地质成图单元。

Typical methods of the first class consist of predictive deconvolution, normal moveout interconversion stacking, f-k transformation, tau-p transformation, parabola Radon transformation and beamforming. They can be called as seismography method based on the geometry. The second class methods, mainly bases on elasticity undulatory theory, through simulation or reversal development method forecast multiple, and then match it with the original data.

比较典型的方法有预测反褶积、正常时差变换叠加、f-k变换、τ-p变换、抛物线 Radon 变换和聚束滤波等，它们可以简称为基于几何地震学方法或"几何滤波类方法"；第二类主要是基于弹性波动理论的方法，通过模拟或反演方法来预测原始数据中多次波，继而从原始数据中匹配减去所预测的多次波。
