介绍了临４５－１０并油层套管事故处理过程和成功经验。处理过程中，采用了长筒套铣工具和内割打捞联合工艺，提高了打捞效率；采用了铣捞式内捞矛工具和小尺寸套管内＂丢引子＂工艺，顺利解决了套管偏心条件下的套铣问题，技术经济效益显著。
Introduced Pro 45-10 and casing accident handling process and successful experience. In the process, long-sleeve milling tools and internal cutting and salvage technology are combined to improve the fishing efficiency. The “fishing lead” technology is adopted in the fishing fishing spear tool and the small-size casing to successfully solve the casing eccentricity condition Under the sleeve milling problems, significant technical and economic benefits.
