摘　　要：从热力学和动力学两种不同的角度分析了水锁伤害产生的原因,总结出影响水锁伤害的内因和外因。在此基础上,从压裂液体系和压裂工艺技术两方面提出了对低渗透砂岩气藏压裂改造中水锁伤害的防治措施,对提高低渗砂岩气藏压裂改造效果具有积极意义。The reasons of producing water-locking damage are analyzed from two different ways,i.e. thermodynamics and kinetics,and the internal and external factors of effecting water-locking damage are summarized. On this basis,measures for preventing and removing water-locking damage are proposed from both fracturing fluid system and fracturing technique. The results of the study will have positive meaning for improving effect of fracture stimulation in low permeability sandstone gas reservoir.
