ABSTRACT:
The method of thermal-mine oil production includes provision of a system of mine workings and at least one operation gallery, drilling production wells from the gallery into the upper and lower portions of the oil-bearing bed, drilling from the gallery injection wells into the central portion of the oil-bearing bed, positively injecting a heat carrier through said injection and production wells into the oil bearing bed to heat the latter to a temperature at which the oil attains the required fluidity within the oil bearing bed, positively feeding a heat carrier via the injection wells into the central portion of the oil-bearing bed for uniform distribution of the heat carrier throughout the body of the oil-bearing bed and forcing oil therefrom into the said production wells. The method further includes collecting the oil from the upper and lower portions of the oil-bearing bed through the said production wells in the operation gallery and directing the oil from the operation gallery through the mine workings to the ground surface.
