API 4 3/4" Downhole Tool CSJ Hydraulic Machinery Fishing Jar
hydraulic up jar is used to be free from drilling sticking, through hydraulic principle, by means of elastic potential produced from drill tool elastic deformation. Once the elastic potential energy is released, it would produce a large up striking load to reach a purpose of fishing and coring. It features easy structures, strong jarring force, easy to return, convenient operation. If it is used with ZJS type jar intensifier, it may gain better jarring effect.
Working Principle
The key principle is: the piston moves up and make hydraulic so that it makes enough time to make drill tool to save energy. With the piston continue to move slowly to releasing bore, after the binding of hydraulic oil is released, elastic potential is released by drill tool saved,immense dynamic loading is passed to drill tool due to jar pads hitting on the bottom of up jar cylinderliner. A desire return mechanism makes a reciprocating jarring action.

1.Hydraulic drill jar
Hydraulic drill jar is an integral hydraulic jar with up jarring and down jarring.when downhole drilling tools are stuck,the jar can provide a huge impact to unfreeze with up jarring. Thus normal drilling operation can be recovered quickly.
When the jar is used. Operators can adjust to picking up it or slacking off it on surface to create up jarring impact or down jarring impact(without addition to the torque or adjustment to the outside part) and adjust impact from very small range to the biggest range needed. The jar can be operated easily and conveniently with high reliability and applied to many downwhole activities of drilling. Coring, fishing, workover etc.
