Abstract：We propose in this paper a new interpretation method for thin beds with the maximum modulus based on the generalized S transform (GST).Based on the spectral decomposition theory and the GST characteristics,we conduct a research on influence mechanism of thin bed response phase spectrum and GST window function phase spectrum on GST time-frequency spectrum.And we put forward an interpretation method aiming at thin bed characterization.A case study shows that the thin beds interpreted on seismic data with the proposed method match very well with that interpreted on logging data.The achieved thin bed characterization proves the reliability and usability of the proposed method.
