The relevance research is caused by need to involve fields with high viscosity oil in development, since low and medium are depleted. Oil directly depends on temperature, therefore, thermal enhanced recovery methods used reduce viscosity. From point view using injected into formation, most effective method cyclic steam stimulation, i. e. injection well. However, when moves through pipe, it condenses, that why production at often has water cut. Accurate calculation entire will help avoid this problem. main aim determine effect inclination angle, quality wellhead, initial pressure conductivity insulation characteristics wellbore, modes. Objects deposits high-viscosity oil. Methods: physical mathematical modeling two-phase (steam-water) reservoir based laws conservation mass, momentum energy, well, loss walls fluid Results. rate was conducted. influence angle (steam quality, wellhead carrier) analyzed. It determined smaller deeper penetrates depth formation.
