摘要 oil and gas producing industry. SUBSTANCE: method may be used for increasing of well productivity. Method includes successive injection into formation of fringes of water-soluble low-molecular solvent, oil-soluble low-molecular solvent and oil. Fringes are injected with ratio of volumes of fringes of water-soluble, oil-soluble low-molecular solvents and oil of 0.35:0.1:0.55.
