摘　　要：胍胶是目前国内油气田压裂改造使用较多的压裂液增稠剂,对一种改性胍胶的水不溶物含量、交联性能及耐温耐盐性能进行评价。实验结果表明,该种改性胍胶压裂液耐温低于50℃,耐盐性能较好,交联剂四硼酸钠交联效果较好,水不溶物含量约6.91%。Guar gum is one of the fracturing fluid thickeners, which was more commonly used in our oil - gas field fracturing treatment. The performances of guar gum such as water - insolube solid content, crosslinking, temperature resistance, and salt tolerance were evaluated in this paper. The results indicated that the guar gum had temperature resistance under 50℃, and its salt - tolerance and crosslinking result using sodium tetraborate as crosslinking agent were good and the waterinsoluble solid content was about 6.91%.
