Secondary changes in reservoir rocks in the territory of Western Siberia have a regional distribution pattern, and the amount of oil and gas resources, that are in these zones, reaches 30 % of their total number. Part of the objects where the secondary changes are most clearly manifested, has not yet been introduced into the development, what requires a more detailed approach to planning and conducting geological exploration work in perspective areas, where pore space is modified by secondary processes. In this work the main factors that control the distribution of the main types of secondary changes in reservoir rocks were identified: lithofacies, chemical and tectonic.
