Product Description

ZSJ/ZXJ Type Drilling Jar (hydraulic-mechanically)

The drilling jar which is connected with drill tool and worked with drill string is a downhole stuck freeing tool in drilling operation .It is a first selected tool for directional well,complicated well and deep well.The drilling jar is consisting of ZSJ type drilling up jar and ZXJ type drilling down jar,both they can be used mutually or operated separately .The up jarring section takes use of hydraulic mechanism,the jarring force can be adjusted according to up elevating load but can not exceed the max.load for tool load rated .The down jarring section takes use of mechanical friction mechanism, the jarring force is well preadjusted by adjusting device before put into downhole.No re-adjustment can be allowed after jar is put into downhole.

ZJS Type Jar Intensifier

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 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 .
