FIELD: oil/gas production. SUBSTANCE: oxygen-containing organic composition, water solution of metal nitrate or mixture of metal nitrates related to beryllium group, bismuth, cadmium, cobalt, manganese, copper, nickel, lead, strontium, aluminum, iron, chromium, tin are pumped subsequently with nitrate content in water solution within the range from 2.0 per cent by weight to the concentration corresponding to saturated solution, and 18 - 35 per cent by weight water solution of hydrochloric acid. Nitrate water solution may content non-ionogenic surface-active substances or mixture of non-iogenic surface-active substances with total content of those in nitrate water solution within 0,001 - 5.0 per cent. Hydrocarbon acid water solution may contents anion, cation, non-ionogenic surface-active substances or mixture of those with hydrocarbon acid water solution with total content of those within 0.001 - 5.0 per cent. EFFECT: increased well productivity. |
