The hydraulic jar is included as
part of a toolstring to help remove stuck tools.
Â
The jar helps free a
stuck tool or toolstring by resisting a pull on the workstring.
When the workstring is stretched by the pull, tension in the jar is
released and an upward impact is delivered to the stuck
tool.
Â
Features and
Benefits
• Design of the
hydraulic system ensures long life with little
maintenance.
Â
• Rig time is
reduced.
Â
• Jar can be recocked
rapidly. Â
Â
• Jar time delay is
adjustable.
Â
• Amount of pull to trip
the jar can be varied within the limits of the time-delay
system.
Â
Operation
The temporary resistance
that powers the jar is provided by a hydraulic time-delay system.
Resistance is released when the metering sleeve inside the jar
moves into a bypass section of the outer case. This action allows
the special hydraulic oil to bypass rapidly.
Â
The time delay required
to release the temporary resistance varies in relation to the
weight of the pull. For example, a light
Â
Â
pull requires more time
for release than a hard pull. When tools below the jar are stuck, a
steady pull applied to the jar creates an upward impact blow to the
string. The jar can be recocked when the string is set
down.
