摘要： A method for using a fracture fluid in forming subterranean fractures includes delaying degradation of a polymer in a fracture fluid when the fracture fluid comprises a breaker by combining at least one radical scavenger with the fracture fluid. The mixture for use in a fracture fluid comprises a radical scavenger and a breaker. A method of fracturing a subterranean formation may include providing a fracture fluid comprising a proppant, a polymer, and a breaker and adding a radical scavenger to the fracture fluid. The fracture fluid is supplied to a desired location in the subterranean formation to form at least one fracture where the viscosity of the fracture fluid is maintained. The breaker is then allowed to degrade the polymer and reduce the viscosity of the fracture fluid at a specific time or temperature.
