Lubricated fishing bumper sub is one of jars which produce jarring
force by means of the energy caused by heavy weight of objects
when move down, its inner chamber is full of hydraulic oil so as to
ensure a longer service life. The tool is suitable for deep hole and
middle deep hole operation. With some advantages: Can produce
strong one way down jarring force, maximum jarring force,
continuous down jarring force, medium jarring force; continuous up
jar, low-grade jarring force; can release fishing tool; can act as
constant pressure drill tool, simply structure, easy operation, all these
make it widely used jarring tool.
