ZJQ型钻井加速器

ZJQ型钻井加速器
ZJQ型钻井加速器利用液体弹簧做为储能元件,作用是为提高液压式上击器震击效果。与JYQ型机械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,最高可提高2倍震击力,同时可以减少震击之后钻柱回弹时的震动,对加速器上部钻具起到?;ぷ饔?。

Drilling Accelerator Type ZJQ

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.
