摘要：

The applicability of existing approaches to the oil seepage simulation in fractured porous reservoirs for the Yarega high-viscosity oil field was studied. The main peculiarity of the oil field is the presence of artificial fracturing, due to a dense network of drilled wells, as well as the use of a thermal-mining technology. A review and a comparative analysis of existing approaches and methods for oil seepage simulation in fractured porous media have been carried out. A criterion is proposed for estimating the relative contribution of the Darcy flow in the porous matrix and the Poiseuille flow in fractures. It is shown that for the conditions of the Yarega high-viscosity oil field the flow in the matrix is several orders of magnitude weaker than the flow in the fractures. A combined model of non-stationary fluids seepage in a fractured porous reservoirs proposed. The model is based on the Euler equations for the motion of fluids in the network of fractures and the "Fractures only" model for oil inflow from the matrix.
