  The present invention provides a process for preparing a stable graft polyol dispersion. The graft polyol dispersion has low viscosity and a high solids content. An ethylenically unsaturated monomer is polymerized in a polyol mixture including a macromer polyol and a carrier polyol. A free radical initiator and a reaction moderator are also present during polymerization. The reaction moderator is of the formula: wherein    R is a phenyl group,    R1 is selected from the group of an aliphatic hydrocarbon radical having 1 to 18 carbon atoms, and    R2 is selected from the group of a phenyl group, a nitrile group, a methoxycarbonyl group, a carbamoyl group, and combinations thereof.

  本发明提供了一种制备稳定接枝多元醇分散体的工艺。接枝多元醇分散体具有低粘度和高固体含量。乙烯不饱和单体在多元醇混合物（包括大分子多元醇和载体多元醇）中聚合。在聚合过程中还存在自由基引发剂和反应调节剂。反应调节剂的结构式如下 其中 R 是苯基、 R1 选自具有 1 至 18 个碳原子的脂肪族烃基，以及 R2 选自苯基、腈基、甲氧基羰基、氨基甲酰基及其组合。

  The addition of at least one promoter selected from the group consisting of thiosulfate salts, sulfite salts, bisulfite salts, erythorbate salts, isoascorbate salts, and combinations thereof to an aqueous treatment fluid containing a viscosifying polymer and a peroxide helps to promote the activity of the peroxide as a breaker, thus facilitating a reduction in viscosity of the aqueous treatment fluid at lower temperatures than are possible in the absence of the promoter. The promoted aqueous treatment fluid is useful as a fracture fluid to fracture subterranean formations in oil and gas recovery.

  在含有增粘聚合物和过氧化物的水处理液中添加至少一种促进剂，这种促进剂选自硫代硫酸盐、亚硫酸盐、亚硫酸氢盐、赤藓酸盐、异赤藓酸盐及其组合组成的组，有助于促进过氧化物作为破坏剂的活性，从而促进水处理液在较低温度下的粘度降低，而在没有促进剂的情况下，粘度可能会降低。经促进的水处理液可用作压裂液，在石油和天然气开采中压裂地下地层。

  A breaker composition for use in a fracturing fluid comprises water, at least one peroxide (e.g., tert-butyl hydroperoxide), and optionally at least one alcohol (e.g., propylene glycol and/or a butyl alcohol). The peroxide(s) and optional alcohol(s) are present in amounts effective to reduce the viscosity of a fracturing fluid at a temperature of 90-300 F. (the “breaking temperature”), and to prevent rehealing of the fracturing fluid, i.e., to maintain the reduced viscosity for a period of time after the temperature is reduced from the breaking temperature to a temperature below the breaking temperature (e.g., after the temperature is reduced from the breaking temperature to room temperature).

  一种用于压裂液的破碎剂组合物包括水、至少一种过氧化物（如叔丁基过氧化氢）和可选的至少一种醇（如丙二醇和/或丁醇）。过氧化物和任选醇的用量可有效降低压裂液在 90-300 华氏度温度（"破裂温度"）下的粘度，并防止压裂液重新凝固，即在温度从破裂温度降低到低于破裂温度之后（例如，温度从破裂温度降低到室温之后）的一段时间内保持降低的粘度。

  A breaker composition for use in a fracturing fluid comprises at least one organic peroxide (e.g., tert-butyl hydroperoxide), at least one dye (e.g., an FD&C dye), and at least one alcohol (e.g., propylene glycol). A promoter composition for use in a fracturing fluid comprises at least one promoter (e.g., sodium thiosulfate), at least one dye (e.g., an FD&C dye). According to certain embodiments, the dye increases the efficiency of the promoter and/or the organic peroxide, so that the break time and the peak viscosity of the aqueous treatment fluid are reduced.

  一种用于压裂液的破坏剂组合物包括至少一种有机过氧化物（如叔丁基过氧化氢）、至少一种染料（如FD&C染料）和至少一种醇（如丙二醇）。用于压裂液的促进剂组合物包括至少一种促进剂（如硫代硫酸钠）、至少一种染料（如 FD&C 染料）。根据某些实施例，染料可提高促进剂和/或有机过氧化物的效率，从而降低水处理液的断裂时间和峰值粘度。
