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.
