Paleoreconstruction of the Krasnoleninsky Field

The basis of the method of paleoreconstruction of accumulation of sediments is the analysis of thicknesses of layers. This method is used to determine the history of sedimentation on Krasnyansky arch and adjacent areas. a paleo-reconstruction of the accumulation of sedimentary was selected on the regional profile of the 2D volume of 526 km, which passes through the Krasnoleninsky arch, also structural maps and lithological description. As a result of this study, it can be concluded that the accumulation of sedimentary material occurred irregularly in the Krasnoleninsky arch and the adjacent areas. More sediment accumulated on the territory of Frolovskaya depression than in neighboring areas. The lowering had Eastern trend. in early Jurassic precipitation accumulated locally on the territory of the Krasnoleninsky arch. in late Jurassic sedimentation was widespread. in Cretaceous and Paleogene time there was a lowering, and in post-Neogene time there was a regional rise in all territory. The presence of carbonate interlayers in the Vikulovskaya suite is a change in the structural plan of the reservoir and the formation of paleo-VNK. This study provides an opportunity to take a different look at the formation of deposits of the Vikulovskaya suite.
