Hydromechanical Drilling Jar Type ZSJ & ZXJ

This hydro mechanical drilling jar consists of two independent components, i.e. hydraulic up jar type ZSJ and mechanical down jar type ZXJ, which can be used either independently or in one. It is connected above the drill string neutral point. When resistance or stuck accident is encountered in downhole drilling operation, the drilling jar can be started to up jar or down jar at any time for relief. It's an important tool to reduce the stuck accident during drilling deep well, complicated well and slant well.
