Геолого-геофизические исследования кольцевых геоморфологических структур на территории юга Русской платформы и перспективы поисков месторождений нефти и газа

Abstract

The use of regional geological and geophysical research methods in the geological and morphological mapping of areas significantly increases the information content and efficiency of predictive exploration of oil and gas research. Aim. To show the possibilities of regional geological and geophysical research methods for studying the morphological concentric features of the tectonic structure and the search for oil and gas deposits within the south regions of the Russian Platform and Caucasus. Methods of research. Various geological and geophysical methods (analysis data of decoding satellite images, of heat flow data) were used. Results of research. The paper revealed the presence of a certain spatial mutual correlational relationship in the location of oil and gas fields in the southern regions of the Russian Platform and Caucasus regions with the location of geomorphological structures of the central type according to the data of decoding satellite images and surveys of heat flow measurements, in the form of ring (sometimes elliptical, spiral) structures. For the first time, the peripheral spatial location (in the side zones) of the main oil, gas, and bitumen deposits relative to the central part of the paleomantle plumes in the southern regions of the Russian Platform, forming geological and morphological structures of the central type, similar to the Pre -Caspian ring morphological structure, where a significant number of oil and gas fields are also concentrated in the southern regions of Russia, is revealed. It is revealed that high values of the heat flow determine the high productivity of oil and gas fields located within the geomorphological structures of the central type. The results of the prognostic assessment in the southern regions of Russia are shown, in order to identify areas that are promising for the search for new oil and gas deposits.
