Annotation:

The development of methods for constructing complex hydrodynamic models of the movement of a heterophase multicomponent fluid, taking into account nonequilibrium processes [1–3, 5–7] occurring both in a porous medium and in volume is an urgent task in the development of oil and gas deposits. Solving this problem allows us to improve the scientific foundations of the technology for influencing the inter-well and near-well space of deposits and control the in-flux of formation fluids to wells in order to increase component recovery and intensify the production of liquid and gaseous hydrocarbons. At the same time, taking into account the results of complex modeling of mass transfer and filtration can have a significant impact on the calculated values of gas-condensate characteristics of reservoir gas-condensate systems and the performance of the gas and condensate production process. The article presents options for constructing hydrodynamic models of the flow of a heterophase multicomponent fluid, taking into account nonequilibrium processes of filtration and diffusion. The proposed hydrodynamic models can also be used to improve the «digital core» technology through the development of software for complex core modeling of mass transfer and filtration processes of formation fluids with a complex composition, including non-hydrocarbon components.
