摘　　要：广安须家河储层具有低孔、低渗、高含水饱和度、强非均质性、储层有效性取决于裂缝发育程度等特点,针对这类储层改造研究形成了CT低伤害压裂液体系。经室内评价和21井次的现场应用表明,该体系具有伤害低、与储层和工艺适应性强、现场应用增产效果显著等特点。The Xujiahe Reservoir in Guang'an has the characteristics of low porosity,low permeability,high water bearing,high non-homogeneity and the availability of the formation is decided by the development degree of the interstice.According to this kind of formation,a CT fracturing fluid system with little damage has been developed.The evaluation in laboratory and the 21 wells applying showed that the CT fracturing fluid system had the characteristics of low formation damage.The fluid system have well adapt to formation and technics,and good gas production effect.
