Hydraulic Drilling Jar 4 3/4''~8'' for Different Well Conditions
Hydraulic drilling jar integrates upward jarring with downward jarring. It is a hydraulic type drilling jar, which is used in all kinds of well condition. It generates up and down jarring force by lifting and releasing drill stems when the drilling tools were stuck and make sure drilling operation can go smoothly. This type drilling jar has some advantages like easy operation stable property safety and reliability maintenance etc.
