SZJQ型双作用钻井加速器

SZJQ型双作用钻井加速器

SZJQ型双作用钻井加速器利用液体弹簧做为储能元件,与QYⅡ型全液压式随钻震击器配合使用,震击作业时能对其下方的钻铤和震击器起加速作用,使卡点获得更大的震击力,可以减少上击或下击作业时产生的震动对加速器上部钻具的破坏作用。
Two-action Drill  Accelerator Type SZJQ

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.
