The article provides brief information on the prospects and features of clarifying the geological structure of the deposits of the Tyumen formation in one of the areas of the Frolov oil and gas region of Western Siberia. The essential initial data for the complex analysis are the materials of 3D seismic surveys, core analysis and well logging. A significant development of disjunctive tectonics was noted for the studied territory, especially on the local arches of structures, which is associated with the activation of tectonic processes in the Jurassic and Cretaceous time. Zones of rock destruction associated with local protrusions of the Pre-Jurassic base have been identified on seismic sections. The predominant transverse size of the identified destruction zones is 150-250 m. The areas of core sampling with signs of fracturing coincide with the position of the selected zones of destruction of rocks. On the basis of a comprehensive analysis, an idea of the models of the formation of hydrocarbon deposits in the area is compiled, the main patterns of the placement of oil-producing sites are proposed, directions for further refinement of the geological structure of the territory and its oil-bearing prospects are determined. The prospects of the Pre-Jurassic foundation are traditionally associated with areas of rock decompression characterized by reduced values of amplitudes and acoustic stiffness, the nature of which is tectonic activity at the site. Productive objects of the upper part of the deposits of the Tyumen formation are characterized by high lithological heterogeneity both in section and laterally, have low filtration and capacitance properties. The main prospects are related to the search for traps and deposits of lithological type, confined to the desalinated zones of the meander belt. Productive strata are an extensive network of channels that can be promising for the detection of reservoirs with relatively high filtration and capacitance properties. It is concluded that it is necessary to use a paleogeodynamic approach when interpreting the results of a comprehensive analysis of seismic data, drilling, core studies and well testing.
