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-Theory of large2step wavefield depth extrapolation
