At present, in the process of depth-domain imaging, the inverse time depth migration of seismic wave is a frequently-used and high-precision method, in contrast to the simulation problem of seismic-wave forward number. The technology about inverse-time migration of seismic waves takes advantage of the exact boundary and discrete calculation to solve the two-way. During the progress of caculation. it’s no need to give up-and down-going wave decomposition. At the same time, it could perfectly handle the problem of multi-valued traveltime. This article maily focused on the basic principles of the inverse time migration of seismic waves and discuss the creation method and fixed way of the primative- velocity model in depth domain. And we used an empirical model to furtherly analysis it.
