FIELD: oil industry. SUBSTANCE: treatment of wells in downhole-adjacent zone plugged by asphatic-resin or paraffin- hydrate sediments is performed by subjecting a well to pumping of compound consisting of alkali and/or alkali-earth metal and/or compound on their base preliminarily mixed with 0.01-5.00% water solution of surface- active matter. Mixture is held until it heats up/ Subsequent washing of well is carried out by way of circulating products of aforesaid metals and water solution of surface-active matter. EFFECT: high efficiency.
