The results of analysis of some geological and geophysical profiles in West-Siberian plate, which based on seismic tomography processing of DSS, data are given. It’s shown that in the upper part of the Earth’s crust there are two refracted boundary. The thickness between them in some regions reaches 10 km and in terms of stratum velocities it is like oil gas volcanogenic sedimentary Paleozoic complex within the Siberian platform. Under conditions of West Siberia the CDP method does not provide the necessary information about the Paleozoic structure. In this connection we used seismic interpretation of CR data processed previously in the region. Processing of previous CR data with two-dimensional seismic tomography can make it possible to get additional geological evidence very important in searching for oil and gas pool in Paleozoic deposits, in particular, to reveal carbonate reservoirs favorable for ПС accumulations in them without laborious and expensive field work.......
