Abstract:Fu11 3-D processing technique was not applied to 3-D seismic data in Jiangsu prospect (Partial processing procedure was finished by using 2-D processing technique),so that the processing effect of 3-D seismic data was not good.To improve the processing effect,we have developed the full 3-D processing technique for 3-D seismic data.The technique includes some parts,namely.preprocessing of 3-D seis mic data,3-D velocity analysis,3-D normal moveout correction,3-D residual static correction,3-D DMO in frequency-wavenumber domain,poststack intertrace interpotation in τ-þ domain,3-D wave equation one-pass migration in frequency-space domain.The processing technique has been applied to the 3-D seismic data from the area where geology structure is very complicated,and it obviously improves the processing accuracy and signal/noise ratio of 3- D seismic section.
