The concept of applying the results of digital core research in the practice of reservoir modeling Sergei V.

   Introduction. The study of the core by mathematical modeling of filtration processes at the level of the void space of the rock has a number of significant advantages relative to traditional laboratory studies. However, there is no
common understanding of how the Digital Core technology can be effectively integrated into practical activities to support the development of hydrocarbon deposits.

   Aim. The purpose of the research is to provide the concept of applying the results of digital core analysis in the practice of reservoir modeling based on the existing experience in using this technology and original developments.

   Materials and methods. The rationale for the concept is based on the most signifi cant third-party and proprietary examples of the use of Digital Core technology to create a petrophysical basis and build a hydrodynamic model.

   Results. Using the Digital Core technology, based on the original semi-empirical core model and hydrodynamic modeling of the facies structure, the problem of taking into account the large-scale effect during the transition from one level of rock to another is solved for one of the sections of the Rosneft oilfield, where pilot works are carried out to displace oil with water and polymer solution. Calculations of relative phase permeabilities in the oil-water and oil-polymer solution systems have been performed. It is shown that the use of the results of digital core studies makes it possible to increase the adequacy of hydrodynamic modeling and thereby reduce the uncertainty of predictive modeling.

   Conclusions. Described the place of applying the results of digital core research in the process of modeling the development of hydrocarbon reservoirs and shown, that it makes this process more logical and more meaningful.
