Imaging complexes geologic structure with single-arrival kirchhoff prestack depth migration

摘要

ew compare various forms of single-arrival Kirchhoff prestack depth migration to a full-waveform, finite- difference migration image, using synthetic seismic data generated from the structurally complex 2-D Marmousi velocity model. First-arrival-traveltime Kirchhoff migration produces sever artifacts and image Contamination in regions of the depth model where Significant reflection energy propagates as late or mul- Tiple arrivals in the total reflection wavefield.
