叠前地震反演道集数据的预处理

The gather data preprocessing of prestack seismic inversion

随着叠前反演技术的推广应用,提高叠前反演质量成为关键,针对叠前反演输入的CRP道集数据开展预处理研究,通过道集水平性和去噪处理,将叠前反演输入地震数据质量明显提升,为后期叠前地震反演提供了的可靠资料基础,起到间接提高反演精度的作用。

With the application of prestack inversion technology,it has become a key to improve the prestack inversion qual-ity.According to the CRP gathers,the preprocessing research was carried out for prestack seismic inversion.By the collection lev-el and denoising preprocessing of the CRP data,the input data quality of prestack inversion was obviously improved,thus provi-ding reliable data basis for the further prestack seismic inversion,and raising the inversion accuracy indirectly.
