The article presents the characteristics of fluid hydrocarbon (HC) accumulations of the Volga-Ural oil and gas basin (OGB) with the identification of types of oils of different ages. The influence of migration processes during the formation of fluid reservoirs in the sedimentary cover of the basin and, in this connection, the possibility of predicting the properties of fluids in non-anticlinal traps of the developed oil and gas bearing complexes (OGC) in the region are emphasized.
Materials and methods
Analytical database of properties of oils from oil and gas complexes of different ages in the Volga-Ural oil and gas field, including data on the content of trace elements in them.
Comparison of the parameters of the oil and gas content of the complex according to geochemical data, a graphical representation of the dependences of the density and physicochemical properties of oils on their tectonic confinement and the age of oil-bearing deposits.
