Briefing
Detailed
The drilling accelerator type ZJQ is run in conjunction with a hydraulic drilling jar of the same size, and is manufactured from high strength alloy steel. The tool can not only strengthen the jarring force, but also can absorb much of the jarring shock from the rebounding string to protect tools and strings from damage.
