Annotation:

This article presents the results of the study of reservoir rocks of the botuobinsky horizon of the eastern slope of the Nepa-Botuoba anteclise and their filtration-capacitive properties through the use of lithological, petrophysical and geophysical studies, including the study of the structure, texture, mineral composition, secondary processes of transformation of rocks, as well as their void space. The results obtained made it possible to identify the main lithotypes of rocks and to identify patterns of their distribution by area and by section. The results of the stadial analysis of lithogenesis, lithofacial reconstructions of sediments, and also the results of lineament analysis helped to determine the role of authigenic mineral formation in the question of the influence of lithogenesis factors on the filtration-capacitive properties of reservoir rocks. Due to the possible connection of authigenic mineral formation with oversaturated fluids seeping through fluid-conducting channels, it was possible to predict promising zones of reservoir rocks of the botuobinsky horizon eastern slope of the Nepa-Botuoba anteclise.
