3D F-T analysis of seismic profile

On the basis of frequency time (F-T) analysis for a single seismic trace, this paper studies the 3D F-T analysis of a seismic profile using the wavelet transform. Once the seismic profile is transformed into a 3D X-T-F data cube, seismic sequence analysis can be done on the 3D cube. Distinguishing the seismic sequence cycle and determining the sequence interface location can be realized in the F-T slice. Tracing continuity characteristics of the sequence interface and picking geological body boundaries and tectonic faults can be implemented in the X-T slice. It becomes the basis for 4D F-T analysis of the 3D seismic data cube and for quantitative interpretation on 4D X-Y-T-F cubes
