A new diverting agent used in  VDA (Viscoelastic surfactant Diverting Acid) was synthesized by our technical team.As a fracturing fluid,the solution of this new surfactant was evaluated according to the petroleum industrial standard and presented excellent viscoelastic properties,the viscosity of which can maintain above 100 mPa.s for 200 min under a shear rate of 100s-1 at 150.The viscous acidizing fluid can be broken into water-like fluid after being fully exposed to hydrocarbons and formation water,and the water-like fluid presented a low damage to the reservior according to the core flooding experiments.
