Description: Theory of large2step wavefield depth extrapolation
Wavefield extrapolation is the foundation of seismic migration imaging. Finding a way of quick and
object oriented wavefield extrapolation is significant not only for deep seismic exploration but also for imaging
with super2tremendous seismic data acquired non2combination receivers , both highly needed to develop in
petroleum prospecting. To image target zones , as far as all present wavefield extrapolation methods are
concerned , including travel2time based Dix2formula methods , ray tracing , small2step depth recursion
