Abstract:

In order to delineate fracture edge information and its multi-scale characteristic in time-frequency domain, a new multi-frequency edge detection(MFED) method based on generalized S transform (GST) is presented, which draw on the idea of wavelet multi-scale edge detection. The MFED achieves highlighting and localizing different scales edge by filtering of different frequencies based on the local time-frequency spectra of GST. The simulation of synthetic signal model demonstrates that MFED can exactly depict the various singular edges and reflect the multi-scale characteristics of the edge, which is similar to the wavelet multi-scale edge detection. MFED is applied to real seismic data processing. The results show that it can detection the fault, the geometry and distribution of fracture zone in different frequency scales.

Key words: generalized S transform, edge detection, fracture zone, seismic singular information, multi-scale
