摘要： A method of fracturing a subterranean formation which surrounds a well bore comprises the steps of providing a fracturing fluid, and injecting the fracturing fluid into the well bore at a pressure sufficient to form fractures in the subterranean formation which surrounds the well bore. The pressure is then released from the fracturing fluid, after which the fluid may be removed from the well and the well placed into production. The fracturing fluid comprises an aqueous liquid, a polysaccharide soluble or dispersible in the aqueous liquid in an amount sufficient to increase the viscosity of the aqueous liquid, an enzyme breaker which degrades the polysaccharide at a temperature above 180° F. Fracturing fluid compositions and enzyme breaker systems useful for carrying out the invention are also disclosed.

摘要： A drilling fluid having a brine base fluid, aluminum chlorohydrate as a viscosifying agent, an alkoxylated surfactant, and an amphoteric polymer encapsulant has been found to have excellent viscoelasticity and suspension characteristics. Surprisingly, it has been discovered that a synergistic effect is present between the aluminum chlorohydrate and the surfactant such that less of each component is required when both are used together to suspend the same amount of solids, than if one or the other is used separately.
摘要翻译：已经发现具有盐水基础流体，水合氯化铝作为增粘剂，烷氧基化表面活性剂和两性聚合物密封剂的钻井液具有优异的粘弹性和悬浮性。令人惊奇的是，已经发现，在水合氯铝酸盐和表面活性剂之间存在协同效应，因此当两者都共同使用时悬浮相同量的固体物质需要较少的每种组分，这要比单独使用或另外使用一种。
