摘　　要：为了解决在煤层气水力压裂过程中由于摩阻过大造成的施工压力偏高和压裂造缝增透效果降低,可以通过向压裂液中加入聚丙烯酰胺减阻并利用沿程阻力实验仪对减阻效果进行评价,优选出最合适的聚丙烯酰胺种类和浓度,在进一步研究后发现聚丙烯酰胺型压裂液还具有防水敏与防速敏作用。In order to solve the high construction pressure caused by friction and the the reduce of fracturing and permeability effect during the process of hydraulic fracturing of coal bed methane,by adding polyacrylamide in the fracturing fluid to reducing the friction and using the on-way resistance experiment instrument to evaluate the drag reduction effect.The most suitable type and concentration of polyacrylamide were selected and in the after further study,the polyacrylamide fracturing fluid was also found could resistance water sensitivity and velocity sensitivity.
