GEOPHYSICAL STUDIES OF RING STRUCTURES FOR THE SEARCH FOR OIL AND GAS DEPOSITS

Abstract

The purpose of this work is to show the possibilities of regional geomorphological and geological-geophysical methods for studying the tectonic and geomorphological features of the structure of central-type ring structures on the territory of the Middle Urals (Tatarstan, Udmurtia, Bashkiria, Kirov Region) and adjacent regions of the Komi-Permyat Autonomous Region, allowing to study the oil and gas prospects of these territories. According to the results of geological and geophysical interpretation of the data of magnetic exploration, gravity exploration and heat flow, the deep structure of the root inhomogeneities of the Voy-Vozhsky ring geomorphological structure of the central type, one of the analyzed in the territory of the Middle Urals, is shown. It is assumed that the intersection points of tectonic faults of the Earth's crust (geomorphological liniments) located in the side zones of circular geomorphological structures of the central type on the territory of the Middle Urals and adjacent regions can be promising objects of geological and geophysical research in search of oil deposits. Gas fields can be confined to the central zones ("pipes" of mantle degassing) of circular geomorphological structures of the central type.
