Abstract: Disclosed are compositions derived of mixtures of choline ion salts (typically choline chloride) in aqueous solution with suspended particulates of sparingly soluble borate minerals or with alkali or alkaline earth borate salts, boric acid and its ester derivatives and salts, or other aqueous soluble borate forms. These compositions are useful as cross-linkers for polysaccharides and other biopolymers and particularly as used in subterranean treatment fluids for completion and stimulation of oil and gas wells. Advantages of the compositions are the combination into a single package of the properties of clay stabilizing actives (choline ion) and crosslinking actives (borates, etc.), in relatively high concentrations, and these compositions are easy to handle, being stable and pumpable at low temperatures, and with attractive environmental profiles. Also disclosed are the analogous choline solutions mixed with metallic cross-linking ions know in the art such as Zr+, Ti4+, Al3+, & Fe3+.
Abstract translation: 公开了衍生自水溶液中的胆碱离子盐（通常为氯化胆碱）与微溶硼酸盐矿物悬浮颗粒或碱金属或碱土金属硼酸盐，硼酸及其酯衍生物和盐或其它水溶性硼酸盐形式的混合物的组合物 。 这些组合物可用作多糖和其它生物聚合物的交联剂，特别是用于完成和刺激油气井的地下处理液中。 组合物的优点是以相对高的浓度组合成粘土稳定活性物（胆碱离子）和交联活性物（硼酸盐等）的性质的单一包装，并且这些组合物易于处理，稳定和可泵送 低温，有吸引力的环境特征。 还公开了与本领域已知的金属交联离子如Zr +，Ti4 +，Al3 +和Fe3 +混合的类似的胆碱溶液。

Abstract: The present invention is directed to fracturing fluids having temperature-sensitive viscosities. The fracturing fluids may include a mixture of a hydrophobically associative polymer (HAP) and a surfactant in an aqueous medium, wherein the surfactant imparts a critical solution temperature (CST) to the fluid. The fluid is more viscous at temperatures lower than the CST as compared to temperatures above the CST.
Abstract translation: 本发明涉及具有温度敏感粘度的压裂液。 压裂流体可以包括水性介质中疏水缔合聚合物（HAP）和表面活性剂的混合物，其中表面活性剂向流体赋予临界溶解温度（CST）。 与CST以上的温度相比，流体在比CST低的温度下粘度更高。
