使用不完全采样反射数据的数据驱动的内部多次波消除应用

Data-driven internal multiple elimination applications using imperfectly sampled reflection data

Joeri Brackenhoff, Johno van IJsseldijk, Kees Wapenaar

摘要:

我们考虑反射数据,已子采样70%,并使用点扩展函数来重建原始数据。二次采样的原始和重建的反射数据被用来与Marchenko方法成像感兴趣的介质。使用二次采样数据获得的图像显示由内部多次波引起的伪影,当使用原始数据和重建数据时,该伪影被消除。

英文摘要:

We consider reflection data that have been subsampled by 70% and use Point-Spread-Functions to reconstruct the original data. The subsampled, original and reconstructed reflection data are used to image the medium of interest with the Marchenko method. The image obtained using the subsampled data shows artifacts caused by internal multiples, which are eliminated when the original and reconstructed data are used.
