Abstract
It has been found that the main oil fields in Western Siberia are attributed to Triassic rifts, because the rifts drain the upper mantle, and the deformations of the sedimentary cover are determined by the basement. On average, the thickness of the basement is 14 times greater than that of the sedimentary cover. Taking into account the mean strength (153 ± 10 MPa) of the basement rocks, the basement strength is two orders of magnitude greater than the strength of the sedimentary cover. The sialic blocks, considered as Precambrian, are composed of light granites and metamorphic rocks. They ascend to the level of the upper crust at the time of Triassic rifting and continued to emerge. As a result, antiforms were formed above the sialic blocks in the sedimentary cover; these antiforms were filled with oil.
