摘要： A drilling fluid and method of using same. The drilling fluid comprises water as a continuous phase, an amount of calcium chloride, and a quantity of a polyacrylamide copolymer. The amount of calcium chloride and the quantity of polyacrylamide copolymer in the drilling fluid are sufficient to produce a rate of penetration approaching that achieved using a synthetic oil-based drilling fluid while preventing substantial screen blinding. In a preferred embodiment, the continuous phase also comprises a second amount of a monovalent salt effective to increase gas hydrate suppression and decrease density when compared to a fluid consisting essentially of only a divalent salt in the absence of the monovalent salt.

摘要： New compositions have been discovered which are useful as slurry concentrates to carry solid particles along in a fluid. A non-limiting example would be to carry proppants in a concentrate to a completion fluid being pumped downhole in a hydrocarbon recovery operation. The composition employs both a trivalent salt, such as aluminum chlorohydrate, as a viscosifying agent, and a surfactant. Surprisingly, it has been discovered that a synergistic effect is present between the aluminum chlorohydrate and the surfactant in 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. The viscoelasticity of the concentrate may be easily broken by dilution; other mechanisms are also anticipated.
摘要翻译： 已经发现了新的组合物，其可用作浆料浓缩物沿着流体携带固体颗粒。 非限制性的实例是在烃回收操作中将浓缩物中的支撑剂运送到在井下泵送的完井流体。 组合物使用三价盐，例如水合氯化铝，作为增粘剂和表面活性剂。 令人惊讶的是，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，因为当两者都一起使用时，需要较少的每种组分，因为如果分开使用一种或另一种，则需要同时悬浮相同量的固体。 浓缩物的粘弹性可能会因稀释而容易破裂; 还预期其他机制。

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.
