Present-day concept of the structure of the Pre-Jurassic basement of the Western Siberia is presented. The geological model of the Western Siberia as geosynclinals model is generally received. The geodynamic approach to this problem has been developing in the last 50 years. This approach based on the theory of the plate tectonics allows to estimate petroleum potential of the pre-Jurassic complex newly. There is opinion the basement of the Western Siberia plate is a continuation of the Central Asian Foldbelt. The contemporary analogue of the Central Asian folded belt is the south-eastern margin of Asia, represented by the junction area of the Indo-Australian and Pacific tectonic plates. Hydrocarbon accumulations various in size including Vietnam oilfields track this area. At present, the pre-Jurassic basement of the Western Siberia (its structure and composition) is insufficiently studied. Analysis of literary data by composition of Pre-Jurassic rocks and the location of oil and gas areas of the globe, the distribution of gas hydrate accumulations and hydrocarbon manifestations in the World ocean in the concept of the plate-tectonic model showed that the pre-Jurassic complex of the Western Siberia is represented by rocks and geodynamic conditions for their formation favorable for the formation of reservoirs and hydrocarbon accumulations. The detailed researches of basement rocks on the developed oilfields carried out by authors earlier showed the rocks was formed in various geodynamic conditions. However, the complex structure of the pre-Jurassic basement – its block structure, intensive disjunctive tectonics and non-uniform development of secondary processes with different directions in relation to the formation of the void space – make the search for hydrocarbon deposits very difficult in it. Found deposits of oil, gas condensate and gas in the Pre-Jurassic basement indicate its prospects for hydrocarbon raw materials.
