Seismic attenuation qualitative characterizing method based on adaptive optimal-kernel time-frequency representation

摘要

The main issue of seismic attenuation characterizing method based on time-frequency analyzing method is the time-frequency resolution. The adaptive optimal-kernel time-frequency representation, which has high time-frequency resolution comparing with commonly used time-frequency analyzing method, is investigated. The seismic attenuation qualitative characterizing method based on adaptive optimal-kernel time-frequency representation is proposed. The synthetic data example and 3D field-data example reveal that the proposed method can qualitatively characterize seismic attenuation, and the attenuated anomaly of this field-data example coincides with gas reservoir well.
