Hydraulic Jar
Hydraulic jar is a kind of security tool. When a packer is stuck, you can use bumper to unfreeze the tool and carry on shocking pipe string. When using this bumper, you should exert a pulling power to the pipe string first, and then releasing the pulling power on the bumper so that the drill stem contracts after the drill stem is stretched. At this time, an impact will act to a jammed tool. If you need multiple shocks, you can operate the bumper repeatedly and repeat the above procedures to obtain.
