【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%。更多还原

【Abstract】 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 water-insoluble solid content was about 6.91%.更多还原
