摘　　要：依据温度稳定剂作用原理,研发了温度稳定剂TA-1,实验结果表明,TA-1浓度为0.1%时,压裂液最高可承受116.3℃高温,与常规压裂液相比,在100℃条件下,压裂液粘度保持100mPa·s以上的时间延长了30min左右,显著提高了压裂液的造缝及携砂性能;其次结合对储层粘土矿物的微观分析,整合粘土稳定剂并对其长效性进行了探索性的评价,最后对胶囊破胶剂(LZEN)与常规破胶剂(APS)复配破胶剂进行了破胶性能评价,并对二种破胶剂整合的比例进行了优化,改进后的压裂液整体性能完全满足压裂工艺技术要求,施工最大井深3460m,最大规模加陶粒100m3,施工总层数近100层,施工成功率95%以上。Based on the action principle of temperature stabilizer, temperature stabilizer TA - 1 is developed. The result of experiment indicates that fracturing fluid enduring the highest temperature is 116. 3℃. When the density of TA - 1 is 0.1%, compared with regular fracturing fluid, the time that viscosity of fracturing fluid holds 100mPa. s is delayed 30min. Solid - carrying performance of fracturing fluid is enhanced dramatically. On the basis of analysis of clay mineral, clay stabilizer is optimized. Its property is evaluated. At last , performance of the gel breaker that consist of LZEN and APS is evaluated, and the matching proportion is optimized. The performance of improved fracturing fluid can meet the needs of fracturing technology.
