Double Acting Mechanical-hydraulic Drilling Jar

SJYZ 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 release block and stuck by several times jarring to recover normal drilling operation promptly. Avoiding resistance and stuck which may cause further accident and caused greater economic loss. If releasing force is failed, it can dynamically adjust at any time on sites.
