QYZ HYDRAULIC DRILLING JAR

SHUANGJIA QYZ 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.

BZ MECHANICAL DRILLING JAR

SHUANGJIA BZ mechanical drilling jar is a full mechanical type drilling jar and releasing stuck tool. It integrates upward jarring with downward jarring releases the tight pull or the sticking or other drilling troubles during drilling. It is a part of drill stem when it needn't jarring and it can work at any time when need jarring. Thus increasing the work efficiency it has widely load (jarring force) scope of the upward jarring and the downward jarring, so it can be adjusted at the maintenance stations or on the well sites according to the requirements. The special flexible joint can reduce the flexural stress of the drilling jar body efficiency. So it is the first selected drilling jar for vertical well, deep well, directional well and complicated well operations.

YJZ HYDRAULIC-MECHANICAL DRILLING JAR

SHUANGJIA 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

SHUANGJIA 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 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 bigger losses. If releasing force is failed, it can dynamically adjust at any time on sites and be easy to use.
