羟丙基瓜尔胶压裂液是一种新型的低伤害压裂液，它适合于地层温度为30～150℃的油层进行压裂改造。该压裂液应用于低温地层（25～50℃）时，是采用氧化剂和激活剂共同作用，达到使压裂液破胶化水的目的。应用于高温地层（120～150℃）时，是采用有机硼作为交联剂，使压裂液在高温深井地层中具有较高的粘度、较好的携砂性，与有机钛交联剂相比，对地层伤害减小。该压裂液已在现场应用237井次，取得了较好的经济效益和社会效益。 Hydroxypropyl guar fracturing fluid is a new type of low pressure fracturing fluid that is suitable for fracturing the reservoirs with the formation temperature of 30-150 ℃. The fracturing fluid used in low temperature formations (25 ~ 50 ℃), is the use of oxidants and activators work together to achieve the purpose of fracturing fluid gelled water. When used in high temperature formation (120-150 ℃), organic boron is used as the crosslinking agent to make the fracturing fluid have high viscosity in high temperature deep well formation, good sand carrying capacity, and organic titanium crosslinker phase Than the damage on the formation to reduce. The fracturing fluid has been applied in the field 237 times, achieved good economic and social benefits.
