ZY-M1505 is a negative-nonionic amphoteric surfactant aimed at Block Ming 15 Zhongyuan oilifeld lfooding. Rela-tionship between surfactant concentration and interfacial tension, thermal stability and oil lfooding performance of ZY-M1505 lfooding surfactant were evaluated in laboratory and then ifeld test was conducted. Experimental results show that under the formation conditions of Block Ming15, the injection water, formation water and surfactant solutions all can achieved to ultra-low interfacial tension, and have long-term thermal stability and a certain ability of oil displacement. Field test results show that the surfactant lfooding enhances the ef-ifciency of oil washing, and improve the test block development state. Production decreasing of this block was signiifcantly reduced, and increasing oil effect is obvious.
