The G Series Drilling Jar is a double-acting hydraulic jar designed to provide additional impact force when the bottom hole assembly (BHA) becomes stuck during drilling operations. It is engineered to be integrated directly into the drill string and features a simple, robust design with high structural strength.

Key characteristics of the G Series Drilling Jar include:

• Downhole Adjustable Impact Force: Allows for controlled and effective jarring tailored to operational needs.

• High Jarring Frequency: Capable of performing more than 500 effective jarring cycles under normal working conditions.

• High Temperature Resistance: Operates reliably in temperatures up to 200°C, suitable for high-temperature wellbores.

• High Pressure Tolerance:

  • Dynamic pressure differential: up to 110 MPa

  • Static pressure differential: up to 140 MPa

• Mud Compatibility: Designed for use in a wide range of drilling fluids, including oil-based muds with up to 90% oil content.

• H2S Resistance: Suitable for sour gas environments.

• Low Pressure Drop: Ensures operational efficiency with a pressure drop of ≤ 0.3 MPa.

With its high reliability, adaptability, and durability, the G Series Drilling Jar is a critical tool for enhancing drilling efficiency, minimizing stuck pipe incidents, and supporting effective directional drilling operations.
