Forecast of hydrocarbons accumulations in the Meso-Cenozoic complex of the Black Sea-Caspian region from modeling results

Abstract

As part of the analysis, it was found that in the Mesozoic, the basins under study were partly part of the Black Sea-South Caspian basin system, and at the later stages of evolution, some of them were involved in tectonic dislocations and, from the point of view of modern tectonic zoning, are partly part of the Alpine folded system. zones. The performed analysis made it possible to establish the main stages of the formation of the sedimentary section, to identify the depocenters of sedimentation on each of them and to reconstruct its evolution. As a result of the studies within the study area, four areas of stable subsidence (basin) were identified during the entire period of formation of the plate cover: Karkinitsky, Indolo-Kubansky, East Kuban and Terek-Caspian. Each of the basins is characterized by a unique evolution, which manifests itself in differences in tectonic mode, sedimentation rates. This determined the features of the geological structure of the basins - differences in the ratio of the thicknesses of the main sedimentary complexe.
