摘　　要：常规石油气资源日益减产,能源资源争夺越发激烈,分布广泛、储量丰富的页岩油气等非常规油气藏成为了化石能源开发的焦点。页岩储层具有低孔、低渗、难以造缝的特征,需采用大规模压裂沟通天然微裂缝,扩宽油气通道,方能形成稳定工业气流实现增产。传统现场粉剂配液模式逐渐无法满足压裂作业要求。因此,本文围绕一体化滑溜水压裂液的优缺点、运用等结合页岩油气开采,概述了国内外一体化悬浮体系压裂液使用状况及相关特点,并综合讨论了在低伤害、环境友好等热点趋势下非常规压裂液的发展方向和特点。Conventional petroleum gas resources are increasingly reduced,and the competition for energy resources is becoming increasingly fierce.Unconventional oil and gas reservoirs such as shale oil and gas,which are widely distributed and rich in reserves,have become the focus of fossil energy development.The shale reservoir has the characteristics of low porosity and low permeability,which is difficult to create fractures.It is necessary to use large-scale fracturing to communicate natural micro-fractures and widen oil and gas channels,so as to form stable industrial gas flow to increase production.The traditional on-site powder dispensing mode gradually fails to meet the requirements of fracturing operations.Therefore,based on the advantages and disadvantages of integrated slick water fracturing fluid and its application in shale oil and gas exploitation,the application status and related characteristics of integrated suspension fracturing fluid at home and abroad are briefly discussed,and the development direction and characteristics of unconventional fracturing fluid under the hot trends such as low damage and environmental friendliness are comprehensively discussed.
