Abstract
Regional 2D seismic explorations of enhanced depth were carried out at the beginning of XXI century for the first time. They allowed together with other geological-geophysical data fundamentally change the model of structure of Yenisey-Khatanga regional depression, Taimyr mountain area, Siberian Platform and Western-Siberian plate. New largest (of superorder and I-II orders) structural-tectonic units were defined on the north of Siberia. Hydrocarbon potential of north-east of Western Siberian, north-west of Siberian Platform and western part of Taimyr fold system was evaluated based on the new attitude. The new hydrocarbon potential sedimentary basin in Riphean-Paleozoic deposits (South-Taimyr oil-and-gas province) was defined on the southern part of Taimyr belt of thrust faults. On the north-west of Siberian Platform the Igarsko-Norilsk oil-and-gas province was defined where the main zones of potential oil and gas accumulation may be megabars with accessible for drilling Riphean-Paleozoic complexes.
