FIELD: production of high-viscosity oil. SUBSTANCE: parallel shafts are drilled from day surface to open the producing formation through its thickness and between shafts and parallel to them are steam-supply, gas-withdrawal and lifting wells are drilled. Working chamber is made between shafts in lower part of producing formation. Drilled from this chamber in two stages are horizontal holes - pressure holes in upper stage, and producing holes in lower stage, and above holes are provided with casing and tubing. Through tubing heat carrier is supplied to pressure holes and at the same time through interpipe space between them and casings is supplied displacing agent. Chamber is tightly isolated from mine atmosphere. Oil pumped to surface by air lift. EFFECT: higher efficiency. 2 cl, 4 dwg
