Zusammenfassung:	oil and gas production. SUBSTANCE: composition intended to increase recovery of oil and gas from formation contains, wt.%: 1.3-% hydrochloric acid solution, 80-96; polyglycol, 3.8-15; oxyethylenated fatty acids, 0.1-2; and neonol, 0.1-3. EFFECT: enhanced well treatment efficiency due to low viscosity and high permeability of composition as well as to decreased velocity and dissolving ability in water- saturated part of carbonate formation and increased dissolving capacity of oil- saturated part of formation. 2 tbl
