| 摘 要： | 根据煤岩储层的特点，介绍了煤层压裂液添加剂的优选和压裂液的常规分析方法，并推荐了两种压裂液，即活性水压裂液和冻胶压裂液，现场应用表明，活性水压裂液对煤层污染较小，适合较低温度（小于30℃）及压裂工艺所要求裂缝较短的情况，冻胶压皮具有一定的耐剪切性，较好的流变性，滤失性及破胶性等，这两种压裂液加砂量均达到了设计要求，满足了工艺需要，施工成功率达100％，压裂后提高了产气量和产液量。

| Abstract: | The optimization of fracturing fluid additives and conventional evaluation arc introduced and two kinds of fracturing fluids are recommended based on coal-bed formation characteristic. Application shows that activated water fracturing fluid exhibit little damage to coal-bed formation with low temperature (less than 30 CO2 and short fissure. Gel fracturing fluid possesses temperature stability, shearing resistance, good rheological property and good gel-breaking capacity with less filtrate. Both fracturing fluids meet the technology requirements ancl the success rate reaches 100%. |
