Abstract: Seismic sedimentology is the subject that using seismic information to study sedimentary rocks and the formation process，it is a new frontier science, which is a new frontier of seismic stratigraphy and sequence stratigraphy. Seismic sedimentology the subject which is using seismic methods to study sedimentary rocks and the formation process, the research method mainly has 90 degrees of phase transition and formation slicing technology. 90 degree phase transformation makes seismic facies with lithology Stratigraphic Significance；stratigraphic section is the plane distribution of the depositional system of the stratigraphic unit, which is used to study the stratigraphic units in each of the strata. In February 2005, the international conference held in the United States of Houston Seismic Sedimentology，following seismic stratigraphy and sequence stratigraphy, seismic sedimentology as a new subject has attracted more and more attention.
