1.Product Introduction
VDA viscoelastic diverting acid, a self-diverting, polymer-free acidizing fluid, can be used in carbonate reservoirs. It is sensitive for pH. The acid enter into High Permeable Zone for reaction, when the pH valve of acid increase,its viscosity grows remarkably, stop the acid enter into the pore path of high permeable zone,the acid continue enter into deeper zone, and divert to low permeable zone that achieve the complete transform for anisotropism reservoir or low permeable zone.
