Seismogeological model of the mesozoic–cainozoic sedimentary cover of the western part of the Vilyui hemisyneclise (by the example of the Srednetyungskoye field)

In the work, a comprehensive interpretation of seismic materials and drilling data was carried out, sets of structural maps and isopach maps of seismogeological complexes were constructed, which served as the basis for structural-tectonic analysis and study of the history of the formation of the Srednetyungsky uplift, which controls gas deposits in the Upper Permian and Lower Triassic deposits. It is concluded that in the relief of the base of the Triassic, the Middle Tyung uplift was formed in the Cretaceous as a result of an increase in tectonic activity in the territory of the entire Vilyui hemisyneclise.
