    摘要: One embodiment of the present invention provides a method of treating a subterranean formation comprising introducing to a portion of a subterranean formation a slurry comprising a solid, particulate chelating agent substantially coated with a degradable material and a viscosified treatment fluid comprising a crosslinked gelling agent, allowing the degradable material to degrade and release the chelating agent into the viscosified treatment fluid; and, allowing the released chelating agent to delink at least a portion of the crosslinked gelling agent. Another embodiment provides a delinker for use in a viscosified treatment fluid comprising a crosslinked gelling agent, comprising a particulate chelating agent substantially coated with a degradable material wherein the degradable material is capable of degrading to release the chelating agent and wherein the released chelating agent is then capable of delinking at least a portion of the crosslinked gelling agent.
