摘　　要：川西地区部分油气储层埋藏深(7000 m左右)、地层温度高(160℃以上),要求压裂液体系具有良好的耐温耐剪切性能。通过优选对压裂液耐温耐剪切性能影响较大的添加剂,并完成相关评价,形成了可以满足160℃和180℃储层施工的超高温压裂液体系。该配方体系在160℃和180℃分别连续剪切120 min之后,粘度仍然可以保持在100 mPa.s以上,满足了超深井压裂改造的需要,填补了川西地区超高温压裂液的空白。Some reservoirs in western Sichuan are deeply buried about 7000m, the temperatures are higher than 160°C, which require that fracturing fluid system has a good temperature and shearing resistance. By optimizing and evaluating the additive which have a significant impact on the temperature and shearing resistance of fracturing fluid, ultra—high temperature fracturing fluid system is formed which can withstand 160°C and 180°C reservoir operation.This formulation can keep enough viscosity above 100mPa. s after it has been sheared for 120 minutes at 160°C and 180°C. This system can meet the requirement of super—deep fracturing well, and fill in the blanks of ultra—high temperature fracturing fluid in western Sichuan.
