摘　　要：针对海上压裂施工利用海水在线快速混配的需求,研究了海水作为配液用水对稠化剂溶胀和交联反应的影响,研制了液体植物胶稠化剂、有机硼交联剂CYS-4,进而研制了耐温达160℃的海水基压裂液体系。实验性能评价结果表明,所研制的海水基植物胶压裂液体系具有良好的耐高温性、破胶性、抗滤失性,可满足160℃以内海水基快速配制压裂施工要求,具有良好的应用推广价值。According to the requirement of rapid fluid preparation with seawater for offshore fracturing , we have analyzed the influences of seawater, as the make -up water , on swelling and cross - linking reaction of thickening agents , developed a liquid vegetable gum thickening agent and anorganic borate cross - linker CYS -4,and further developed a seawater -based fracturing fluid system which with stands temperatures up to 160℃ . Evaluation results from lab experiments indicate that the seawater -based vegetable gum fractu -ring liquid system possesses properties of high temperature resistance,easinessin gel breaking and low fil -tration , hence can satisfy the operation requirement of rapid preparation of the fracturing fluid undertem -peratures up to 160 ℃,and has a promising dissemination potential.
