摘　　要：从储层保护的角度把裂缝性储层分成两大类 ,即中小裂缝储层和大裂缝储层。分析了在钻井过程中两类储层的主要伤害机理 ,在此基础上提出 :以中小裂缝为主的储层 ,应选择常规钻井工艺下的屏蔽暂堵钻井技术保护储层 ;对于以大裂缝为主的储层 ,应选择负压欠平衡钻井工艺保护储层 。From the point of formation protection, the fractured reservo irs are c lassified as reservoir with small to medium fractures and reservoir with large f ractures. The main damaging mechanisms of the two different types of reservoirs are analyzed, and it is presented that temporary shield plugging technology of c onventional drilling should be selected for reservoir with small to medium fract ures; while for reservoir with large fractures, underbalanced drilling technolog y should be used for formation protection. The key techniques for the operations are also introduced briefly.
