摘　　要：综述了当前主要的压裂液对页岩储层造成的伤害情况,重点分析了页岩储层结构和孔喉特征与压裂液水力尺寸的匹配情况,总结了压裂液对页岩储层造成伤害的类型和原因,包括压裂液对储层的敏感性伤害,压裂液返排时对渗透率的影响,压裂液对油气扩散和解吸的伤害,提出了未来页岩压裂改造过程中降低储层伤害的技术方法和发展趋势。The damage caused by the main fracturing fluid to shale reservoirs is reviewed,the matching of shale reservoir structure and pore throat characteristics with the hydraulic size of fracturing fluid is analyzed,and the types and causes of fracturing fluid damage to shale reservoirs are summarized,including the sensitivity damage of fracturing fluid to reservoirs,the influence of fracturing fluid on permeability during reflux,the damage of fracturing fluid to oil and gas diffusion and desorption,and the technical methods and research directions for reducing reservoir damage in the process of shale fracturing transformation in the future are proposed.
