The role and significance of the tectonic-stratigraphic factor in the formation of the structural features of hydrocarbon deposits of the Volga-Ural oil and gas province

The article establishes the role and importance of the tectonic-stratigraphic factor in the formation of the structural features of hydrocarbon deposits in the Volga-Ural oil and gas province. It has been established that the type of reservoir, tectonic and stratigraphic confinement of the objects of study determine the geological and physical features of the deposits by more than two thirds and are the basis for the identification of objects at a qualitative level. An algorithm is proposed for selecting analogous objects at a qualitative level for deposits emerging from exploration in the absence of representative data on the geological, physical and physico-chemical properties of formations and fluids based on its belonging to a stratigraphic system, tier, horizon, tectonic element.
