曲波域逆散射级数层间多次波压制方法
Inverse scattering series method for interbed multiple suppression in curvelet domain
摘要
Abstract
In seismic exploration,multiples pose a significant issue,particularly in marine exploration.This study developed a method for suppressing interbed multiples based on the inverse scattering series method in the curvelet domain.The curvelet transform(CT),as a multi-scale and multi-directional transformation method,can sparsely represent seismic data,facilitating the capture of the main features of seismic data.By combining CT with the inverse scattering series method,the seismic data was first converted to the curvelet domain using CT.Then,the interbed multiples were predicted in the curvelet domain through the inverse scattering series method.This approach did not require building a model of the subsurface medium,offering high applicability and practicality.Furthermore,CT can sparsely represent seismic data,reducing the computational load of the inverse scattering series method.By performing an inverse CT on the predicted multiples,they were recon-structed in the time-space domain and subtracted from the original seismic data,ultimately obtaining the effec-tive signal with suppressed multiples.The numerical experiments demonstrate that this method not only signifi-cantly improves computational efficiency but also reduces memory consumption while ensuring accuracy.This study provides an innovative approach for suppressing multiples in seismic data processing and is expected to play an important role in practical seismic exploration.关键词
