Significant oil and gas potential are associated with deep-seated sediments of the Vuktyl autochthone in the area of development of the Vuktyl thrust. The least studied is the Visean terrigenous productive reservoir of the Lower-Middle-Visean oil and gas complex. Conducted a detailed correlation of the studied sediments. From 3 to 6 sandy layers in the thickness of clay rocks are allocated, depending on the location of the wells. Variable sediment thickness is noted. The presence of repetitive sand formations of bar genesis is shown, which can be considered as a result of unstable development of the territory, successive changes of regressions and transgressions against the background of the predominance of transgressive development.
Materials and methods
Materials: the geological map, the data of geological studies, stratigraphy, tectonics and petroleum potential of the Verkhnepechorsky depression.
Methods: construction of geological profile and modeling of steam reservoir of the visean sandstone
Results
Paleostructures were carried out to identify facies features of the section according to GIS and core data in order to clarify the prospects of oil and gas potential of deep-loaded sediments.
Conclusions
As a result of the refinement of the structure, the sandy layers of the Visean reservoir are defined as lithologically limited and tectonically screened from the east by an overthrust trap in which the reservoirs are the Bobrikov and the Lower-tulsky sandstones.
A new level of understanding of the structure of oil and gas complexes can become the basis of a new cycle of exploration and resource base.
