| 摘 要： | 七里 2 5井因抢险下入CYY344— 14 6可钻式机械桥塞 ,封闭了产层和原井油管落鱼。后因恢复生产需打捞桥塞及其下部落鱼。因落鱼腐蚀严重 ,不能采用传统磨铣桥塞的方法。该井采取先对桥塞钻孔 ,再磨铣打捞桥塞的办法使该井复活 ,为其它井下封隔工具的创新使用和处理提供了良好借鉴。

| Abstract: | For preventing the emergency,the CYY344-146 drillability mechanical bridge plug is tripped into well Qili-25,the payzone and tube fishes are sealed.For restoring production,it is required to fish the bridge plug and fishes.Because the fishes are corroded seriously,the traditional method of milling bridge plug can't be adopted.So the bridge plug is first drilled a hole in the middle,then milled and fished.The method makes the well restoring production and provides a good reference for disposal and using the other sealing tools. |
