Brief of Hydraulic jar


Hydraulic Jar is a kind of safety tool. When testing tool get stuck, you can use bumper to unfreeze the tool and carry on 

shocking pipe string. When using this bumper, you should exert a pulling power to the pipe string first, and then

 releasing the pulling power on the bumper so that the drill stem contracts after the drill stem is stretched. At this time, 

an impact will act to a jammed tool. If you need multiple shocks, you can operate the bumper repeatedly and repeat

 the above procedures to obtain.


Features of Big John Jar
• Design of the hydraulic system ensures long life with little maintenance.

• Rig time is reduced.

• Jar can be recocked rapidly.

• Jar time delay is adjustable.

• Amount of pull to trip the jar can be varied within the limits of the time-delay system.

The Full bore hydraulic jar is designed for easy control of the jarring action by the operator. The time delay impact control is allowed for by use of Flow Restrictors between the upper and lower oil chambers. Fluid flow is restricted only in the upward pull direction so the jar is easily reset for subsequent jars.
