Abstract
In this paper, the authors refine the geological-facial model of sandy-silty-clayey rocks of the AV1 1-2 horizon with “ryabchik” texture. The work is based on new coring data in intervals of weakly permeable strongly clayey reservoirs. The conducted studies updated current understanding of lithofacies features of the reservoir. Based on results of the presented analysis, an own petrophysical reservoir model is based, which makes it possible to increase detail of identification productive intervals and establish petrophysical dependencies.
