3D F-T analysis of seismic profile

摘要

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