Abstract:

This paper expounds first on the advantages of Time-Frequency Analysis(TFA)technique in fine description of graded pattern of sedimentation. Then it specifies the optimization design of T-F filter with frequency recursion based on the practicability of T-F filter principles and performs T-F analysis of seismic responses generated by a theoretical cycle model of tectonic geology built through forward simulation method. It finally offers an evaluation of practical application through interpretation and comparison of the simulated and the real cyclicity.

Key words: sequence cycle, filter, seismic interpretation, time-frequency analysis
