摘要

Time-frequency (TF) analysis is a powerful tool in seismic data processing and interpretation, and it characterizes the frequency response of subsurface rocks and hydrocarbon reservoirs effectively. In this letter, we proposed a new method called the second-order synchrosqueezing wave packet transform (SSWPT2) for seismic TF analysis. The proposed approach introduces two posttransform, i.e., reassignment method (RM) and synchrosqueezing transform (SST), into the wave packet transform. Such a technique achieves a highly concentrated TF representation by using a second-order local estimate of the instantaneous frequency (IF). We validate the proposed approach with a synthetic example and compare the result with the existing methods, and field data examples also illustrate its effectiveness in delineating more distinct channels in the horizon slices.
