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。
