Device and method for de-blending simultaneous shooting data with apex shifted radon transform |
摘要 |
<p>A device, medium and method for de-blending seismic data associated with a subsurface of the earth. The method includes receiving blended seismic data, wherein the blended seismic data includes traces having energies from two or more different shots that partially overlap; applying an apex-shifted radon transform (ASRT) to the blended seismic data to transform it from a first domain to a second domain; applying a mute processing for removing all shots except a first shot in the second domain; applying a reverse ASRT to the given shot to obtain the first shot in the first domain; and generating an image of the subsurface based on the first shot in the first domain. The procedure may be iteratively repeated to separate all shots. U) 6 V LL 00) r r < C) 00Cr _ ~ _ _</p> |
