FIELD: oil and gas producing industry; applicable in treatment of bottom-hole formation zone. SUBSTANCE: method provides for use of thermochemical treatment. For this purpose, two reagents reacting with liberation of heat are delivered to bottom hole. Thermochemical treatment is carried out concurrently with mechanical treatment. After removal of treatment products by washing, bottom-hole formation zone is subjected to treatment in medium of solvents. During withdrawal of formation products, annular space is evacuated up to moment of stopping of pressure drop at well head in annular space. EFFECT: higher productivity of well. 4 dwg, 1 tbl
