摘要：
This invention relates to an anionic-cationic-nonionic surfactant as substantially represented by the formula (I), production and use thereof in tertiary oil recovery. The anionic-cationic-nonionic surfactant of this invention exhibits significantly improved interfacial activity and stability as compared with the prior art. With the present anionic-cationic-nonionic surfactant, a flooding fluid composition for tertiary oil recovery with improved oil displacement efficiency and oil washing capability as compared with the prior art could be produced. In the formula (I), each group is as defined in the specification.
