The new steam generator with supercritical parameters of the steam injected for oil recovery enhancement of heavy high-viscosity oil formations, laying at a great depth of 1000-2000 m, is designed. A pilot efficient thermal insulation of pipes, parts and components on the basis of oxides of silicon and aluminum with special additives for injection wells is developed. It is noted that the mobile steam generator plant with capacity up to 10 t/h of steam with supercritical parameters in combination with heat-insulated downhole equipment will provide oil recovery enhancement up to 40% compared to the hard-to-recover oil reserves.
