Thickener for Viscosity-variable Acid

The drag reducer for integrated variable-viscosity acid has the characteristics of multi-liquid integration, delayed viscosity change, and on-line liquid preparation. By reducing the construction friction resistance, increasing the displacement, decreasing the acid-rock reaction rate, and realizing shunt redirection within the fractures, it can meet the requirements of deep, volumetric and three-dimensional acid fracturing stimulation for carbonate reservoirs at 200℃.
