Abstract：Routine seismic geometry evaluation method based on stratified medium assumption has limitation in complex structure area,based on seismic wave propagation theory and by integrating the adaptability of the shooting and receiving conditions in reflection seismic exploration to complex subsurface structure dip,a new seismic geometry evaluation method which is based on wave equation directional illumination and is feasible in complex structure areas was proposed in this paper.With the new method the shot-points and receiver-points directional illumination to subsurface structures was synthetically considered,and the seismic geometry can be evaluated for the dip angle and the reflection angle of subsurface structure in the target zone.
