摘要： A method of treating a subterranean formation penetrated by a wellbore is carried out by providing a treatment fluid comprising a hydratable polymer, a divalent metal salt in an amount of at least about 0.25 mol/L and an aluminum crosslinking agent. The fluid is provided with a pH of from about 5 or higher. The treatment fluid may be caused to contact the formation by introducing the fluid into the wellbore. The fluid may optionally contain a polyol.

摘要： This invention relates to compositions and methods for treating subterranean formations, in particular, oilfield stimulation compositions and methods using water-in-water polymer emulsions to uniformly dissolve a rheologically active polymer, such as a thickener or friction reducer, in the treatment fluid. The emulsions have a low viscosity and are easily pumped for mixing into a treatment fluid, where upon dilution with an aqueous medium, the polymer is easily hydrated without forming fish-eyes. The partitioning agent in the water-in-water emulsion does not generally affect the rheology of the treatment fluid. The invention also relates to further processing of the emulsion by wet grinding, high shear mixing and/or heating to enhance the hydration rate in the preparation of the well treatment fluid.
摘要翻译：本发明涉及用于处理地下地层的组合物和方法，特别是油田刺激组合物和使用水包水聚合物乳液在处理液中均匀溶解流变学活性聚合物如增稠剂或摩擦减小剂的方法。乳液具有低粘度并且容易地泵入以混合到处理流体中，其中当用水性介质稀释时，聚合物容易水合而不形成鱼眼。水包油乳液中的分配剂通常不影响处理液的流变性。本发明还涉及通过湿法研磨，高剪切混合和/或加热进一步处理乳液，以提高在井处理流体的制备中的水化速率。
