摘要： Gellable treatment fluids may have their gel times modified by using a polymer mixture therein that contains two or more polymers having disparate average molecular weights. Methods for treating a subterranean formation using such gellable treatment fluids can comprise providing a gellable treatment fluid comprising a polymer mixture and a crosslinking agent, introducing the gellable treatment fluid into a subterranean formation, and allowing the gellable treatment fluid to form a gel in the subterranean formation. The polymer mixture comprises a base polymer and an addend polymer, where the base polymer and the addend polymer each comprise an acrylamide monomer unit or a derivative thereof and have different average molecular weights, such that a molecular weight distribution of the polymer mixture contains at least two local maxima.

摘要： A hydration acceleration surfactant may be utilized in conjunction with high molecular weight polymers in forming high viscosity, aqueous based treatment fluids. Forming such fluids may involve mixing an aqueous base fluid, a hydration acceleration surfactant, a crosslinker polymer, and a base polymer, thereby yielding a treatment fluid, wherein the base polymer is provided in the form of a first polymeric emulsion before mixing and/or the crosslinker polymer is provided in the form of a second polymeric emulsion before mixing. Further, such fluids may be useful in subterranean operations to perform for at least one function within the wellbore and/or the subterranean formation including bridge a fracture, provide fluid loss control, seal a rock surface, enable fluid diversion, plug a void, reduce formation permeability, control water production, and any combination thereof.
