Oil and gas presence perspectives of weathering layer reservoir of Nurol'ka mega-basin according to data of geothermics

There were examined the issues of studying the features of the lithological and petrographic composition and the formation of oil deposits within the fields of the Surgut dome fold and the Frolov megadepression. It was noted that the formation of deposits of the sedimentary cover is associated with the peculiarities of the geological structure and the oil-bearing capacity of the basement rocks. In the considered territory, a high level of oil-bearing sedimentary cover is observed within the central part of the Surgut dome fold, and the deposits of the Pre-Jurassic part of the section can be additional sources of intensification of hydrocarbons in the Lower-Middle Jurassic deposits. The presence of zones of deep snaps is a search criterion for the detection of secondary reservoirs in them both — in destruction zones, basement, and in the Lower-Middle Jurassic deposits, therefore, deposits can be formed due to the vertically ascending migration of deep fluids through faults that cross the basement and horizons of the sedimentary cover.There were examined the issues of the prospects for the oil and gas content of the Lower-Middle Jurassic deposits, which must be associated with both granitoid massifs and the details of identifying the conditions of sedimentation and the establishment of contact zones of the sedimentary cover with the underlying formations.
