The article presents the results of studying the conditions for the formation of hydrocarbon accumulations in uplift-thrust structures of the eastern side of the Pre-Ural fore deep, where intense cover-folded dislocations of the western vergence are manifested. Their formation is associated with the intercontinental collision that occurred when the Ural paleoocean was closed at the very end of the Paleozoic, and in the extreme northern segments of the belt, probably at the very beginning of the Mesozoic. Structural paragenesis of the eastern side includes over-thrusts and thrusts, as well as various scaled structural forms formed under the action of latitudinal compression. For the zone of the Forward folds of the Urals located in the South Ural segment of the eastern side of the belt, numerical basin and geomechanical modeling was performed, a series of paleotectonic reconstructions was constructed. It is shown that the fold-uplift-thrust and subnadge structures of the zone of the advanced folds of the Urals are favorable for the formation of hydrocarbon deposits. This conclusion is obviously true for all similar thrust structures of the entire eastern side of the Pre-New-Land belt of oil and gas accumulation.
