Abstract
Based on the detailed analysis of the characteristics of seismic data in the diapir fuzzy region, an effective data processing strategy has been developed in order to solve the problems, such as the multiple wave interference from a rough seafloor, the absorption of high frequency components caused by shallow gas diffraction, and the poor imaging caused by complex fault structures. By using the signal fidelity technology, combined technology for suppressing multiple waves, signal enhancement technology to improve the SNR, high precision seismic velocity modeling and anisotropic prestack depth migration and other key processing technology, the seismic data in the diapir fuzzy region is greatly improved in signal-to-noise ratio and suppression of multiple wave interference, and therefore greatly improved in the imaging quality of seismic profiles.
