MODEL PREDICTION OF MULTIPLE ELIMINATIONON IN YINGGEHAI BASIN

The Yinggehai basin is a Cenozoic petroliferous basin in offshore China. Overpressure and overtemperature deposits are widely distributed in the basin. It makes the seismic multiple similar to the primary in both frequency band and velocity, so the multiple is very difficult to be attenuated. In this article we provided two kinds of method for shallow water multiple attenuation in the Yinggehai basin. It is proved that the methods are effective to get high SNR and high resolution.
