Seismic Data Interpretation after PSDM in Depth Domain

The prestack depth migration(PSDM) could have good image in complex area of velocity or geological structure,and has become standard process in seismic data processing.The seismic interpretation to the cube after PSDM could be carried out in depth domain or time domain by depth-time transformation.There are many advantages to interpret seismic cube in depth domain,although some difficulties exist,such as the applicability of convolution model,how to conduct seismic-well ties,and depth correction for map and cube,and so on.On the basis of previous study and work practice,and approach has been approved which is adapt to the current interpretation system,existing workflow,and work ideas.
