REGULARITIES OF ACCOMMODATIONS OF MAIN TYPES OF SECONDARY CHANGES OF COLLECTORS IN THE TERRITORY OF THE WEST SIBERIAN PLATE
To date, hydrocarbon raw materials play an important role in the economy of the Russian Federation. Federal state statistics service of Russia Federation data show that for the first seven months of 2018, revenues from hydrocarbon production accounted for about 40 % of all federal budget revenues, and this number will only increase in the near future. However, in the last fifteen to twenty years in the main oil and gas bearing provinces, including the Western Siberia, have seen a stable decrease in production levels. New opportunities to change the current trend is to involve in the process of developing oil and gas deposits in poorly studied areas with a high density of hydrocarbons. Such objects, as a rule, are characterized by an extremely complex geological structure and the presence of different types of secondary changes of rock-collectors. Despite the large number of such objects, at the moment there is not only a clear classification of the main types of secondary changes, but also the patterns of their location and, as a result, the methods of prospecting and exploration of deposits of this type are not sufficiently developed. In this paper there made an attempt for generalize the extensive material on the study of collectors with a modified pore space structure and to determine the main patterns of location of the main types of secondary changes on the territory of the West Siberian Plate.
