Detailed

The mechanical drilling jar type JZ takes the appliance of mechanical structure. And high pressure will not produce in inner chamber as to create a good sealing property and greatly extend the service life. During the drilling operation, the jarring mechanism has no action due to its unique structure which can not be controlled by the common drilling condition and torque, and its unique structure can accurately transmit the torque. Moreover, the up or down jarring blow is adjustable prior to tripping in and will not change during the downhole operation so as to keep a constant jarring load.
