Product Description

QYZ Hydraulic Drilling Jar
QYZ hydraulic drilling jar integrates upward jarring with downward jarring. It is a hydraulic type drilling jar, which is used in all kirds of well conditicn, 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.

YJZ Hydraulic-mechanical Drilling Jar
YJZ hydraulic-mechanical drilling jar integrates hydraulic principle with mechanical principle, it's a new type drilling jar, which can suit for all kinds of drilling operations, and go with drilling tools assembly to descend the well when used. The drilling tools are often sticked due to many kinds of reasons in down hole when in normal drilling operations, and this type drilling jar is an effective tool for releasing stuck. When the drilling tools are sticked, it can make drilling jar generate upward or downward jarring force through lifting and landing the drill strings, so it can release resistance and the stick by many time jarring, and recover normal drilling operation promptly. Meanwhile avoid resistance and stick to become further accident, and cause larger economic losses. If releasing force is failed, it can dynamically adjust at anytime on sites and be easy to use.

SJYZ Double Acting Mechanical-hydraulic Drilling Jar
SJYZ double acting mechanCcal-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.
