摘　　要：分析总结了我国近年来在低渗储层钻井储层保护方面取得的进步。通过分析低渗储层伤害因素,将在钻井方面进行的储层保护技术总结为几种典型的储层保护措施。总结认为,钻井储层保护从降低固相、液相侵入,避免液相圈闭以提高气藏启动压力,分解近井壁堵塞层等方面进行了理论创新和实践应用,形成了多种先进技术,现场应用效果明显。The article analyzed and summarized the progress we made in the reservoir pro- tection drilling process of low permeability reservoir recent years.By analyzing the factors that hurt low permeability reservoir, it summarized reservoir protection technologies in driiling process into several typical reservoir protection measures.It concluded that reservoir protec- tion drilling process had made theoretical innovation and practical application in several as- pects such as reducing drilling solid,liquid intrusion and avoiding liquid traps to raise gas reservoirs starting pressure and decomposing near wellbore blockage layer, it had formed a variety of advanced technologies and field application result was outstanding.
