| 摘 要： | 评价了羧甲基羟丙基瓜尔胶（CMHPG）压裂液在90～180℃的流变性与伤害特征。该稠化剂水不溶物含量低于1.1%,用于180℃储层的加量为0.60%,基液黏度88.6 mPa.s,交联液在170 1/s剪切100 min后的黏度大于50 mPa.s。0.25%交联液100℃时的储能模量为2.451 Pa,大于0.50%羟丙基瓜尔胶（HPG）交联液的0.7265Pa。CMHPG交联液在低破胶剂浓度下即可快速破胶水化,残渣含量为194～225 mg/L,不到HPG的1/2。CMHPG和HPG交联液对储层岩心的伤害率分别为39.8%、52.3%。CMHPG交联液悬砂性能良好。在排量2～6 m3/min时,0.45%CMHPG压裂液基液（用于150℃高温深井）的摩阻系数与0.30%HPG基液（用于70℃地层）相当。与HPG压裂液相比,CMHPG压裂液具有高弹性、高悬砂性及低稠化剂使用浓度、低基液黏度、低伤害、低摩阻的＂二高四低＂性能。图5表8参4
