Based on the previous research, combined with exploration practice, it is considered that as a new frontier interdiscipline subject which uses seismic data to study sedimentary rock and its forming process, seismic sedimentology has its unique theoretic basis based on the theories of the modern sedimentology and the geophysics. Its theoretical innovation mainly displays in the following two aspects: ①a depositional body is easier to be resolved with seismic data in horizontal dimension than in vertical; ②primary seismic reflection events do not necessarily follow the geologicaltime surfaces,the seismic frequency content of the data controls the dip and inner reflection configuration of seismic events. These two principles are the basis for using horizontal seismic attributes(seismic geomorphology) to study the sedimentary facies and their evolution,which are the core ideas of the seismic sedimentology.
