摘　　要：采用水力式割刀分段割断事故钻杆,可退式捞矛捞取事故钻杆的处理方法,快捷、安全、经济地处理了招远栾家河金矿区47ZK3孔深孔跑钻事故。结合该工程实例,介绍了水压式割刀和可退式捞矛的使用方法,并与传统的反丝钻杆和丝锥锥捞处理方法进行了比较。The drill sliding accident was handled by drill rod section-cutting with hydraulic cutters and fishing with retrievable spear in 47ZK3 of Luanjiahe gold mine in Zhaoyuan of Shandong. With the engineering case, the paper introduces the usage of hydraulic-pressure cutters and retrievable fishing spear, and presents the comparison between this and conventional fishing by reverse-thread drill rod and screwing fishing.
