ALL-PURPOSE JARS
The all-purpose RJ2-2HM jars combine mechanical and hydraulic features.
- The hydraulic section functions both during the strain and compression of the jar
- The mechanical section rules out unintentional firing during drilling or tripping
- The jar can be installed at any place in the drill string, both above and below the neutral point
- The main feature of this design is jarring against a stuck point with a variable pull/push and magnitude of impact in either direction
- Recommended for use in highly deviated holes with a high friction coefficient where it is problematic to generate a load sufficient to reset the jar
Ensure excellent performance in highly deviated holes and at a high friction coefficient
Can be used at 200° C when fitted with high-temperature seals
