Abstract: Based on the composition structure of viscoelastic surfactant (VES),micelle change mechanism of VES was described.Through wide investigations on present situation of VES in Chinese and foreign oilfields,mechanisms and applications of separate types of VES in clear fracturing fluid,self-diverting acid and some other techniques were systematically introduced.Moreover,existing problems were summarized and studied.VES has wide application prospects in fracturing,acidizing,tertiary oil recovery,drilling fluid and fluids drag-reducing transportation because of its special micellar structure and rheological property.At the end,working emphases and research trends in this field were proposed.

Key words: viscoelastic surfactant, clean fracturing fluid, self-diverting acid, application
