Four-in-one liquid: Fracturing fluid, acidic/slickwater, gelled acid, and crosslinked acid

Excellent drag reduction effect: The drag reduction rate is ≥75%.

Good compatibility performance: There is no problem of incompatibility between the acid solution and conventional fracturing fluid

Good viscosity increasing performance: The viscosity is higher than that of conventional acid thickeners

Low residual acid viscosity: It can break the gel thoroughly, is easy to flow back, and causes little damage to the reservoir
