Formation and placement of oil and gas traps within the junction area of Cis-Ural trough and West-Ural outer folding zone
Background. The Cis-Ural trough and its junction area with the West-Ural outer folding zone are known as structures with high oil and gas potential. However, the complexity of the geological structure, due to the wide development of faults of various genesis and morphology, the discrepancy between t...

| description | Background. The Cis-Ural trough and its junction area with the West-Ural outer folding zone are known as structures with high oil and gas potential. However, the complexity of the geological structure, due to the wide development of faults of various genesis and morphology, the discrepancy between the structural plans of parts of the sedimentary section, etc., as well as the low quality of the available seismic material and, as a result, unreliable geological models of the object are a deterrent to the development of the resource base of the area under consideration. Aim. To study the formation conditions and to typify oil and gas traps within the junction area of the Cis-Ural trough and the West-Ural outer folding zone. Materials and methods. A series of seismogeological profiles in the sublatitudinal direction was used for the research: No. 2622001-02 ShP in the interpretation of Drozdov V. V., Krasnovishersk-Severouralsk in the interpretation of Popov A. G., No. 15-RS in the interpretation of Makarevich V. N. The technique of structural-kinematic modeling was used, which allows reconstructing the structural evolution of fold-thrust zones. Results. Based on geological and geophysical data and using modern computer modeling technologies, a substantiated conceptual geological model of the formation and structure of the junction area of the Cis-Ural trough and the West-Ural outer folding zone was created. Oil and gas trapswere predicted and their types were determined. Conclusion. Conditions for the formation, preservation and placement of oil and gas traps within the junction area of the Cis-Ural trough and the West-Ural outer folding zone were studied. The types of the traps were determined, which, in conjunction with the analysis of hydrocarbon systems, creates the basis for a scientifically robust assessment of the prospects for oil and gas potential of the studied area. |
