The development of clean fracturing fluid has become the trend for increasing production in oil and gas fields.In this paper,a viscoelastic surfactant blend system with 90℃resistance was studied,suitable additives were screened out,the optimal blend ratio was determined,and its temperature and shear resistance properties were tested.The future trend of viscoelastic surfactants is also discussed.
