Abstract: Seismic sedimentology is a new research field proposed during studies of the marine strata abroad in recent years, but its application to continental lake basins is urgently required to explore in technique. This paper analyzes the limitations of such three key techniques of seismic sedimentology as90°?phase conversion, strata slicing and frequency decomposition interpretation, and points out that the90°?phase conversion technique needs comprehensive consideration of the matched geologic body thickness and the frequency components of seismic data; strata slicing technique can be used for interpretation of sedimentary facies, but need to adopt different ways of slicing, according to different types of sedimentary facies;3D visualization sculpture technique of geological body can be applied to seismic sedimentology, solving3D interpretation problem of complex reservoir sediments
