摘 要:井下破损油管落物的常规打捞方法是先磨铣鱼顶至规则形状,再采取内捞或外捞的方式实施打捞,造成了施工工序复杂、工期长,严重影响油水井的正常生产。研制的井下破损油管打捞筒用于直接磨铣修整鱼顶进行打捞,具有操作灵活、安全性能可靠、提高修井时效的作业特点。介绍了该装置的结构、工作原理、技术参数及使用要求。现场使用证明,具有良好的推广应用前景。In the course of water-oil well repair,the way of routine of breaking fishes in well was to mill fishes head to get the rule shape,then inner or outer fish for fishes was used.But this way caused structure process complicated and exceeded time limit for a project,thus a strong impact was over normal activity in water-oil well.We developed the basket barrel overshot of the breakage oil pipe in well to be used to mill and nap the fishes head,salvage,this basket barrel overshot have operating agility and security credibility,raising repair well aging.This article introduces this device structure and work theory,technical parameter,operation.This device was proved to have favorable promotion foreground on the spot.
