Introduction：

The fully hydraulic drilling jar is a downhole tool designed for jarring and stuck pipe release while drilling. Its triggering mechanism is entirely hydraulic, capable of performing both upward and downward jarring operations. The tool is simple to operate and delivers greater impact force than mechanical jars of the same specification. The driller can adjust the speed and tonnage when pulling up or lowering the drill string to achieve different jarring intensities. Once the tool is positioned and ready, pulling up or lowering the drill string followed by a waiting period of 30 to 240 seconds will activate the jarring action. This tool enables rapid and effective resolution of downhole sticking incidents, such as pipe jamming or obstruction, during drilling operations.

Features and Benefits：

★ It delivers a greater impact force, which can be precisely controlled by adjusting the drill string speed.

★ The triggering mechanism is fully hydraulic, making operation simple while ensuring a powerful impact force.

★ It features a short waiting time after setting, enabling quick jarring and efficient stuck pipe release.
