The ZJS type jar intensifier is a downhole fishing jar designed to increase jarring energy to up jar. Therefore it must be run in conjunction with CSJ type super jar or YSJ type hydraulic up jar.Its function is mainly to supply acceleration to the upper end of the jar during the free jarring stroke. With a special function, the intensifier is essentially a fluid spring which not only can accelerate the up jarring action but also make the jarring action directly to strike on the fish and reduce damages to the drill tool and fishing tool .
