Detailed
The hydro-mechanical drilling jar consists of two independent comonents, i.e. hydraulic up jar type ZSJ & mechanical down jar type ZXJ, which can be used either independently or in conjunction. It is connected near the drillstring neutral point for necessary use. When resistance or stuck accident is encounted in downhle drilling operation, the drilling jar can be started to up jar or down jar at any time for relief. Therefore, it is an ideal, indispensble tool for drilling directional well, complicated well and slant well.
