Hydraulic Jar Big John Jar For Cased Hole Drill Stem Testing 5" x 15000psi
Introudction of Hydraulic Jar
The hydraulic jar is the Halliburton Big John Jar, which is used as a safety tool in the well downhole testing operation. The Hydraulic Jar is used to provide an upward shock to helps free a stuck tool by resisting a pull on the workstring.
When a packer is 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 the end of the stroke, the restriction is removed causing the mandrel to move rapidly upward, resulting in a sudden impact to help free the stuck tools. If the tools are not free, a downward stroke resets the Hydraulic Jar for the next attempt.
Application of the Hydraulic Jar
* Drill stem testing Operation
* Tubing - converyed perforating operation - TCP operation
* Oil well flow operations
