Study on system of broad - spectrum oil - film temporary plugging drilling fluid
暂堵钻井液体系研究
In view of the reservoir characters of severe heterogeneity , wide pore radius distribution , unpredictability of pore radius , and unrealized protection for whole hole section and bad protection effect by conventional shielding temporary plugging technology , we designed a broad spectrum oil film temporary plugging drilling and completion fluid system for reservoir protection
摘要针对油层非均质性强、孔径分布范围较宽、油层孔径难以准确预知，常规屏蔽暂堵技术几乎无法实现对整个油层井段的保护、油层保护效果差等特点，设计了广谱“油膜”暂堵型保护油层钻井完井液体系，并进行了室内系统评价和现场应用。
