Key Technique of Surface Related Multiple Elimination
Multiple is a kind of common coherent noise on marine seismic record. In order to overcome the influence of multiple wave and wavelet in the multiple wave prediction when using raw seismic data,a method that uses reflectivity method to form a synthetic shot,then combine the synthetic shot with the raw data to predict the multiple wave model can be used. This method can overcome the lack of spatial sampling and overreach of prediction to a certain extent Huber norm limited by time window method can give more accurate estimation of multiple and the method can overcome the mismatching of multiple wave and effective signal. This method has achieved good effect in multiple elimination both in model data processing and actual data processing.
