Seismic sedimentology is a subject using seismic method to make researches on sedimentary rocks and their formation processes.It is a new marginal intersection subject following the seismic stratigraphy and sequence stratigraphy.Using the technologies of frequency division,phase shift and stratal slicing,this paper studies seismic sedimentology of the organic reef from the Changxing Formation of Sichuan basin.The results show that using the frequency division technology can create fine isochronous stratigraphic framework; phase shift seismic data are similar to wave impedance data and prone to interpretative; the combination of stratal slicing and seismic attributes analysis is more effective than the conventional amplitude slices on capturing the tiny lateral changes and displaying the various depositional characteristics.Examples showed that seismic sedimentology has unique advantages in the analysis of sedimentary facies and the forecast of organic reef.
