摘要
介绍了ＨＺＹ－１和ＨＺＹ－２低温破胶压裂液的配方选择及破胶剂浓度、激活剂浓度和温度对其破胶化水性的影响。川西坳陷蓬莱镇组致密砂岩气藏近１００井次的应用表明，平均单井产量可提高１０～１５倍，施工成功率９９．１％，有效率９０％，经济效益显著，是国内致密砂岩气藏增产措施的一个重大突破，具有推广应用价值。
The formulation selection of HZY1,HZY2 lowtemperature fracturing fluid for gel breaking is given in the paper.The influences of gel breaker density,activator density and the temprature on gel breaking are introduced.The applications in nearly one hundred wells show,the output per well can improved by 10-15 times on the average,the success rate is 99.1%,the effective rate is 90%.It is worth widely using.
