摘要： The present invention relates to encapsulated breakers and the use of encapsulated breakers for breaking viscosified treatment fluids. One embodiment of the present invention provides a method of providing a viscosified treatment fluid having a first viscosity having a gelling agent, a crosslinking agent, a proppant, an aqueous-base fluid, and an encapsulated breaker composition having an encapsulant that has a poly(meth)acrylate blend; introducing the viscosified treatment fluid in the subterranean formation; creating or enhancing a fracture in a subterranean formation; and allowing the encapsulated breaker composition to release the breaker so as to reduce the viscosity of the viscosified treatment fluid to a second viscosity.
