摘　　要：研制了大口径井专用电磁打捞器,基于装置的结构设计论述了其电磁铁模块、可拆卸式滑轮模块、降阻导流模块、可选装式打捞篮模块、水冷技术、防水技术的特性、关键功能及研究意义,开展了应用试验。结果表明:研制的大口径井专用电磁打捞器运行稳定、可靠,打捞成功率高且井间通用性强,可满足大口径钻井施工中金属落物事故处理需求。A new special electromagnetic fishing device for large diameter wells is developed. Based on the structural design of the device, the characteristics, key functions and research significance of its electromagnet module, removable pulley module,resistance reduction and flow diversion module, optional fishing basket module, water cooling technology and waterproof technology are discussed, and its application test is carried out. The results show that the electromagnetic fishing device developed for large diameter wells operates stably and reliably with high success rate of fishing and strong inter-well commonality, which can meet the needs of handling metal falling accidents in large diameter drilling construction.
