Abstract: The problems’ solving of heat and mass transfer during the cyclic steam stimulation of the bottom-hole zone of the production wells allows us to control the process of high-viscous oil extracting. Based on the mechanics of multiphase systems development approaches, a mathematical model is formulated and a criterion method for the steam injection time determining into the bottomhole zone is proposed. Within the framework of this method, the following processes are crucial: heat transfer to the roof and bottom of the reservoir, the water-saturated zone increase during continuous injection, and the presence of a limiting pressure gradient in a non-Newtonian fluid. The developed model was tested on the synthetic data. The development dynamics of thermal, steam-water and oil-water fronts during injection in the radial formulation of the problem are investigated. The model was verified based on a comparison of the results obtained with calculations in a hydrodynamic simulator.
