Complicated Salt Strata Influence on the Seismo-Geological Model of Subsalt Structures in the Kaliningrad Region

The report is devoted to the problem of complex geological objects influence on the seismo-geological model of underlying depositions. Complicated salt layer in the Kaliningrad region was studied as an example. Different methods of time-to-depth conversion under foregoing conditions were compared. It was noted that interpretation of prestack depth migration results in depth domain is the most appropriate under complicated seismo-geological conditions. Considering the situation it should be mentioned that in order to obtain the reliable result of deep migration, special attention should be paid to the creation of correct depth velocity model.
