Hydraulic Drilling Jar

Hydraulic Drilling Jar

In normal drilling operations, down hole drilling tools assembly was stuck sometimes due to many kinds reasons, and drilling jar is an effective tool for releasing stuck. QYZ type hydraulic drilling jar integrate upward jarring with downward jarring, It can start drilling jar by lifting and releasing drill stem when drilling tools were stuck, so it will generate up and down jarring force, and make sure drilling operation can go smoothly. This type drilling jar has some advantages like easy operation, stable property, safety and reliable, easy maintenance, etc..
