分别以十二烷基和磺酸盐甜菜碱为修饰基团，以瓜胶原粉为主剂，制备了2种改性瓜胶增稠剂：疏水改性羟丙基瓜胶和磺酸盐甜菜碱型瓜胶。模拟现场配方，对其配制的压裂液的抗剪切性能和耐温性能进行评价。通过对比发现磺酸盐甜菜碱型胍胶比油田提供CJ2-6胍胶耐温抗剪切能力有所下降，疏水改性羟丙基胍胶比油田提供CJ2-6胍胶耐温抗剪切能力有明显改善。其中，疏水改性羟丙基瓜胶80℃下剪切60 min 后，表观粘度为93．4 mPa· s，比油田提供CJ2-6瓜胶耐温抗剪切能力有明显改善。可以考虑疏水改性羟丙基瓜胶在压裂液体系的进一步应用。

Two modified guar-based fluids were prepared using meloncollagen powder as the main agent , halogenated dodecylane and sulfonate betaine as modified groups ,respectively.According to oil field,the shear ability and temperature resistance were evaluated .It was found sulfonate betaine-type guanidine gum are less tolerant of high-shear conditions and high temperature than CJ 2-6 guanidine gum ,while the hy-drophobic modification of hydroxypropyl guar gum are less tolerant of high-shear conditions and high tem-perature.Among them,the apparent viscosity of the hydrophobically modified hydroxypropyl guar gum re-mains 93.4 mPa· s for shearing 60 min at 80℃.Considering the hydrophobically modified hydroxypropyl guar gum in the further application of fracturing fluid system .
