| Abstract: | The seismic data in LSH deepwater area is collected by long arranged streamer,however,as the work area is large,the speed variation is sensitive and anisotropy is obvious in the area,the traditional artificial velocity analysis can not meet the needs of exploration and development in this work area.Through the research of CGGVeritas’s high density spectral analysis technique,it proves that this technique can better solve the problem of NMO correction and improve the speed accuracy and density of the deepwater seismic data with high efficiency and high quality.Therefore,the technique is applied widely to the whole area,and has achieved very good results. |
| Keywords: | deepwater seismic data long spread density bispectrum anisotropy nmo correction |
