FIELD: chemistry.
SUBSTANCE: invention relates to a surfactant composition, production and use thereof in tertiary oil recovery. Surfactant composition comprises a cationic surfactant composition and an anionic-nonionic surfactant composition, which exhibits considerably improved interfacial activity and stability in comparison with the prior art. Said composition is used to prepare a flooding fluid for oil recovery using tertiary methods, which has a significantly improved oil displacement efficiency and oil washing capability in comparison with the prior art. Invention is developed in dependent claims of the formula.
EFFECT: higher processing efficiency for oil recovery.
