Product Description

Product Description

This type of drilling jar is connected to the drill string to help release stuck drill tools during drilling operations and ensures that drilling operations can be resumed promptly. This product is especially recommended for directional, complicated and deep wells.

This drilling jar consists of two components, the ZSJ type drilling up jar and ZXJ type drilling down jar. These components can be operated together or exclusively. The up jarring portion utilizes the hydraulic system, allowing the jarring force to be easily adjusted by the tool elevation load. The jarring force should not exceed the maximum rated load of the tools. The downward jarring portion utilizes the mechanical friction mechanism. However, the jarring force can only be pre-adjusted mechanically on the drilling jar prior employing it in the downhole drilling operation.
