Beschreibung
Zusammenfassung:	oil and gas production. SUBSTANCE: invention relates to thermochemical intensification of inflow of hydrocarbons from productive formation consisting in injection of combustive and oxidative composition into combustion initiator treatment zone, said composition being based on alkali metal borohydride and methanol or diethyl ether, 5-95%; or alkali, 5-25%; and/or solid isopropylcarborane, 5-40%. Composition for instance contains, wt.%: complex compound of oxalic diamide with nitric acid, 18-36; acetyl salicylate, 4-5; potassium permanganate, 0.01-0.05; isopropylcarborane, 5-15; water, 9-18; and ammonium nitrate, the balance. EFFECT: enhanced treatment efficiency. 8 cl, 1 tbl
