Super fishing jar
CSJ type super fishing jar is a fishing tool that the jarring force larger than other jar with same specification. It features a closed structure, reliable performance, easy to adjust and easy to operate. It is a new type of up jarring tool used in oilfield, geological exploration and drilling operation.

The ZJS type jar intensifier is a down hole 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 mainly is to 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 that 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.
