| 摘 要： | 针对目前压裂井越往深井发展地层温度越高这一问题,研究开发了一种由耐高温改性瓜胶、有机硼锆交联剂和温度稳定剂等形成了超高温压裂液体系,即0.55％超高温改性瓜胶+1％温度稳定剂BA1-26+0.5％助排剂BA1-5+0.5％黏土稳定剂BA1-13+0.02％杀菌剂BA2-3+2％KCl+0.6％交联剂.用AFM、SEM观察了压裂液交联前后的微观结构,并考察了压裂液的相关性能.实验结果表明,超高温压裂液具有良好的抗剪切能力,180℃、170 1/s下剪切2 h后,黏度仍保持在150 mPa·s以上；通过调节pH可使超高温压裂液的成冻时间控制在3～15 min之间,有利于深井施工；交联前压裂液的线形结构有利于提高降阻性能,交联后压裂液的三雏结构有利于携砂.破胶液外观清澈透明、黏度较低(＜6 mPa·8)、表面张力低(为28.6 mN/m),残渣率为10.6％.现场实施进一步证明研制的超高温压裂液能满足180℃地层的压裂要求.图4表2参12
