Ultimate Hydraulic / Mechanical Drilling Jar
Brand: Wenzel Downhole ToolsThe Ultimate Hydraulic/Mechanical Drilling Jar (UHMJ) is a double acting jar, designed to deliver hydraulic delay when jarring in the up direction, and mechanical release when jarring in the down direction.
Using proprietary new technology, Wenzel Downhole Tools has been able to dramatically increase the allowable overpull force.
The UHMJ incorporates a latch mechanism to keep the jar locked in the neutral position and eliminate unexpected jarring while tripping or racking on the derrick.
Features- The UHMJ is normally operated in the latched position to reduce unexpected jarring while drilling and eliminate movement between jar components, increasing service life.
- The UHMJ operates with a simple up and down motion and is not affected by torque.
- The spline drive and latch mechanism are enclosed in a single, sealed oil chamber without ports to the annulus. Such ports on other jars may fill with cuttings and restrict the down jar stroke.
- The hydraulic delay mechanism is located in a separate chamber to prevent contamination and increase reliability.
- With the latch mechanism in the latched position, the inner mandrel and outer housing act integrally, virtually eliminating seal and inner tool wear during normal drilling conditions. There is no need to extend or open the UHMJ before running in the hole.
- Standard seals in the tool are effective to 250°F (120°C). The jar can be dressed with seals effective to 400°F (200°C) for hot hole environments, and 450°F (230°C) for extreme temperature environments. External sealing surfaces are tungsten carbide-coated to enhance wear and corrosion resistance
- The UHMJ can be run in tension or in compression within the preset latch settings.
