In recent years, with the deepening of hole drilling and the continuous increasing of complex drilling workload, drill pipe sticking and breaking accidents frequently occur. Under the conditions of broken drill rod with irregular fractures or unsuccessful fishing by conventional fishing cone, the retrievable fishing spear can be used to deal with the accident quickly and effectively. Combined with 2 engineering examples, this paper introduces the retrievable fishing spear about its use method and advantages; and puts forward some suggestions in view of the problems in using process, which can be reference for dealing with the similar downhole accidents.
