GENERAL GEOLOGICAL BASES OF OIL AND GAS GEOLOGICAL ZONING OF THE RUSSIAN AND FOREIGN RESEARCHERS

The general geological foundations of oil and gas zoning are laid down by Russian and foreign researchers and are carried out according to different principles, which reflects the ambiguity of many researchers ' views on the genetic aspects, the mechanism of formation of oil and gas accumulations, and other issues of oil geology. The development of a sedimentary basin and its transformation into an oil and gas basin is accompanied by complex and long-term intermittent-continuous processes determined by tectonic laws that control the formation of platform, geosynclinal and oceanic structural elements of the earth's crust, within which these basins are located. The zoning scheme is based on a complex of various geological indicators that determine the time and conditions for the generation, migration, accumulation and preservation of hydrocarbon accumulations. When comparing the Russian and international schemes of regional studies, it becomes obvious that the essence of research does not change either in the domestic scheme or in the Western classification.
