摘要
双重介质储层受损害的主要原因,是外来液相的侵入或固相颗粒的堵塞。在对双重介质油气储层特征、损害机理进行分析的基础上,提出了适合储层特性的优质钻井液体系。其屏蔽暂堵钻井技术和欠平衡钻井工艺,是保护此类储层有效手段。
The invasion of extrinsic liquid phase and the plugging of solid-phase particle are the main factors which damage dual-media reservoirs. A high-quality drilling-fluid system which is suitable for reservoir characteristics is present in this paper based on the analysis of dual-media reservoir characteristics and damage mechanism. The system includes screening temporary-blocking and underbalanced drilling technologies which are effective tools to protect the reservoirs.
