摘　　要：页岩气开发需要体积压裂开采,与瓜尔胶体系相比,滑溜水压裂液因施工泵压低、胶液黏度易调节,成为页岩气开采常用压裂液技术。我国西南地区页岩气资源丰富,现采用聚丙烯酰胺为减阻剂的滑溜水体系,单井注液量上万立方米、排量16~20 m^(3)/min,对滑溜水指标提出更高要求。因此,滑溜水压裂液用聚丙烯酰胺特性分析对页岩气、页岩油的开发提供了重要的技术支持。Shale gas development requires volumetric fracturing.Compared with guar gum system,slick-water fracturing fluid is becoming a common fracturing fluid technology in shale gas exploitation due to its low pump pressure and easy viscosity adjustment.Shale gas resources are abundant in southwest China,and the slippery water system with polymer as drag reducing agent is now used.The injection volume of a single well is tens of thousands of square meters and the displacement is 16~20 m^(3)/min,which puts forward higher requirements on the cost of slippery water.Therefore,the characteristic analysis of polymer used in slick-water fracturing fluid provides important technical support for the development in shale gas and shale oil.
