Product Description
double acting mechanical-hydraulic drilling jar integrates upward jarring with
downward jarring and has all advantages of both mechanical drilling jar and hydraulic
drilling jar, it applies to all kinds of drilling operations and be used through combining
with drilling tools. When the downhole tools get struck, it can generate upward jarring
or downward jarring through lifting and landing drilling strings, and also release meeting
resistance and free stick by many times jarring to recover formally drilling operation
promptly. Avoid meeting resistance or free stick to become further accident and cause more
bigger losses. If releasing force is failed, it can dynamically adjust at any time on sites and
be easy to use.
