摘要
针对复杂情况下卡钻事故的处理,逐步采用了强力起拔工艺、套铣打捞工艺以及磨铣松扣工艺处理卡钻事故。并利用扩孔钻头+母锥打捞处理卡钻事故过程中打捞钻杆发生的二次断裂事故,在将断裂的打捞钻杆套出后,利用磨铣钻头成功磨铣松扣被卡定向钻杆,回收大部分被卡定向钻杆以及断裂的打捞钻杆。保证了该孔的有效性,并为后续分支孔及钻孔的施工提供了必要条件。
In view of handling sticking accident in the complex, the use of a strong pull, fishing and ~ And the use of biche assembling reamer bits to deal the accident of fishing rob fracture. After of the successfully fish the fishing rob, the use of milling bit to successfully fish the directional drill stems, recycling most of the fishing rods and the directional drill stems. To ensure the effectiveness of the hole and provide the necessary conditions of the drilling construction.
