摘　　要：研究了我国煤层气储层孔隙和裂隙系统特征,分析了煤层气钻井的储层伤害机理。针对煤层气钻井储层保护难点,建议采用低固相或无固相钻井液、欠平衡钻井技术、屏蔽暂堵技术和加强固相控制等来保护煤层气钻井储层。The porosity and the fracture system characteristics of domestic coal - bed methane reservoir were studied, and the mechanism of reservoir damage by drilling in coal - bed methane was analyzed. In view of the difficulties in coal - bed methane drilling reservoir protection, it is recommended that low solid drilling fluid or solid free drilling fluid, under - balanced drilling technique, shielding temporary plugging technique and solid control technique, etc. be used to protect the coal -bed methane drilling reservoir in this paper.
