GEOLOGICAL STRUCTURE AND OIL AND GAS POTENTIAL OF THE PRE-JURASSIC DEPOSITS OF THECENTRAL PART OF THE WEST SIBERIAN PLATE
In the presented work the features of the geological structure and oil and gas potential of the pre-Jurassic basement rocks are discussed. In the sediments of the oil and gas bearing horizon of zone of contact five types of reservoir rocks are distinguished. The greatest prospects for oil and gas potential are associated with the carbonate depositions of the Middle Paleozoic and effusive of the medium-acidic composition of the Permian-Triassic and Triassic age. From these deposits in the territory of the district the maximum oil inflows were received. 15 promising zones of oil and gas accumulation in the deposits of the oil and gas bearing horizon of zone of contact were distinguished, three of which are poorly studied by drilling and one zone (Predeniseyskaya) is in the Paleozoic oil and gas complex.
