An integrated approach for seismic prestack depth migration in complex media
- and others
In order to solve the imaging problems in complex media, this article presents an integrated approach of seismic prestack depth migration, which is based on the Kirchhoff`s migration theory and combined with regional geological model. The flow of this approach includes three main parts: (1) seismic data preprocessing, (2) velocity-depth model building , and (3) prestack depth migration and imaging. An example over the complicated structural zone of the ZX Paleozoic buried hill in eastern China is given here; and the result of prestack depth migration, NE206 seismic profile, shows the top and inside of the ZX buried hill and overthrusts more clearly comparing with poststack migration data.
