At the present time, the largest oil fields in Russia are characterized by significant depletion of petroleum reserves and high water content in the extracted products. Therefore, oil fields of complex structure (e.g., fractured-porous collectors contained bottom water) saturated with hard-to-recover non-Newton oil are increasingly involved in the practice of oil production. With the time, the share of them grows constantly and, in this regard, the problems of increasing the oil recovery of such oil reservoirs and the choice of a rational regime of their operation are of particular relevance. 

The solution of actual problems of the commissioning into the operating regime and cyclic exploitation of the unified oil producing complex results in a need to construct a digital twin of the interrelated processes of heat and mass transfer in multiphase flows moving in different areas of this complex, taking into account the work of the controlling devices such as the automatic controller of the surface control station and the regulating drossel.
