It integrates the up jarring with the down jarring
hydraulic-mechanical drilling jar
1.The hydromechanical drilling jar consists of ZSJ type drilling up jar and ZXJ type drilling down jar, both they can be used mutually or operated separately .
2.The up jarring section takes use of hydraulic mechanism, the jarring force can be adjusted according to up elevating load but can not exceed the max. load for tool load rated .
3.The down jarring section takes use of mechanical friction mechanism, the jarring force is well preadjusted by adjusting device before put into downhole.
4.No re-adjustment can be allowed after jar is put into downhole
