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,简要给出了实施各种工艺的技术要点。

Abstract

From the point of formation protection,the fractured reservoirs are classified as reservoir with small to medium fractures and reservoir with large fractures.The main damaging mechanisms of the two different types of reservoirs are analyzed,and it is presented that temporary shield plugging technology of conventional drilling should be selected for reservoir with small to medium fractures;while for reservoir with large fractures,underbalanced drilling technology should be used for formation protection.The key techniques for the operations are also introduced briefly.
