Dual functional components and associated methods |
摘要 |
Many methods and compositions are provided. One of the methods provided comprises the steps of: providing an aqueous treatment fluid that comprises a polysaccharide and a dual functional component, the aqueous treatment fluid having a first viscosity; allowing the dual functional component to interact with the polysaccharide such that the viscosity of the aqueous treatment fluid increases to a second viscosity, the second viscosity being greater than the first viscosity; placing the aqueous treatment fluid into a subterranean formation; and allowing the dual functional component to interact with the polysaccharide so as to reduce the second viscosity of the aqueous treatment fluid to a third viscosity, the third viscosity being less than the second viscosity. An example of a composition is a viscosified treatment fluid for treating subterranean formations comprising: an aqueous base fluid and an apparent cross linked reaction product of a polysaccharide and a dual functional component.
