官方备注
Overshots are well drilling machine tools used to grip and retrieve objects stuck within a wellbore by lowering the tool over the object. Wellbore fishing refers to recovering lost, damaged or stuck objects from the wellbore in oil and gas drilling. The objects lost down the well are generally referred to as "fish."
