INDICATORS OF PETROLEUM REGIONS IN THE RUSSIAN PROVINCES WITH VARIOUS STRUCTURES

V. S. Staroseltsev

As the role of tectonic zonation as the major criterion of outlining of petroleum regions has been gradually reducing, the author examined the main petroleum-bearing and promising regions. The Lena-Tunguska petroleum province holds key position in this regard, which extends through the most part of the Siberian Platform, where most petroleum provinces are confined to the largest (superorder, as classified in 1963) plicative structures. The same is true for the Khatanga-Vilyui province outlined previously in the Siberian Platform after the author suggested the updated geological oil and gas zonation in 2012. In other petroleum provinces of Russia the position of petroleum regions is more often controlled by plicative structures of the first, rarer second orders or their aggregates, rarer fragments of superorder structures, e. g. the Cis-Caspian syneclise sidewall parts. Aulacogenic structures of the Timanka-Pechora petroleum province inherited from the Riphean basement structures play a special part in revealing of petroleum regions. The Dnepropetrovsk-Pripyat’ gas-oil-bearing province outlined within the Russkaya Platform (in its Ukrainian part) is an example of direct connection of geological oil and gas zonation with rift structures. The priority of tectonic controls is evident in the lucrative West Siberian petroleum province, where the prevailing factor is the oil and gas geological section structural features.

Key words: petroleum provinces and regions, controls of geological oil and gas zonation, orders of structures, inherited features, geological oil and gas section.
