FIELD: oil-and-gas production.
SUBSTANCE: for heating of sandstones, slates and bitumens there are used pressed plain thermit from aluminium powder and crocus. It is controlled time combustion temperature, pressure of carbon dioxide and combustion time. Then it is loaded into well powder of ferrous oxide for providing of endoergic reaction of thermofusion with conversion of carbon dioxide into ethane. At pressure fall of carbon dioxide it is added aqueous suspension of carbon iron of 30 % concentration and it is synthesized from ferric carbide for dissolving of bituminous materials. Additionally temperature in well is isolated at the level 300 degrees centigrade.
EFFECT: increasing of recovery factor of oil-and-gas bearing stratums from petrolic sands, slates, bituminous materials.
