Description
API Drilling Accelerator
ELITE model “ZJQ” Drilling Accelerator can be stored energy by hydraulic spring as to increase the jarring force for Hydraulic Jar. It should be applied with Hydraulic Drilling Jar Type QYⅡ jointly.
The drill collar and Hydraulic Jar (below the Drill Accelerator ) can function an accelerated effect when jarring operates as for making the stuck point gain more jarring force that can increase force for two times at the highest. Meanwhile, it can decrease the bounce-back shock after jarring as to protect the drill tools above Drill Accelerator.

API Two-action Drilling Accelerator
ELITE two-action Drill Accelerator Type SZJQ can be stored energy by hydraulic spring. It should be applied with Model QYⅡ Hydraulic Drilling Jar jointly. The drill collar and Hydraulic Jar (below the Drill Accelerator ) can function an accelerated effect when jarring operates as for making the stuck point gain more jarring force. Meanwhile, it can decrease the damage of tremor produced by up-down jarring for drill tools above Drill Accelerator.
