Abstract

The method for thermoshaft oil production comprises the provision of a combination of mining holes above an oil-bearing bed which are inclined at from 1.degree. to 3.degree. to the horizon. Then injection holes are drilled from these mining openings for feeding a heating medium into the bed. After that, a slope and a footway leading to the bottom part of the oil-bearing bed are constructed, and a production gallery is provided within the bottom part of the bed. Horizontal and ascending holes are drilled from the production gallery for oil production. A heating medium is fed into the injection holes for uniform distribution thereof over the entire volume of the oil-bearing bed and for displacement of oil into the horizontal and ascending production holes towards the production gallery wherefrom the oil is fed up to the surface.
