Drilling Jar

Mechanical Drilling Jar
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 anytime when need jarring. Thus increasing the work effciency. 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 effciently. So it is the frst selected drilling jar for vertical well deep well directional well and complicated well operations.

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 decont the well when uesd. 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 dynamiclly adjust at anytime on sites and be easy to use.

Hydraulic Jar Intensifer
YJS hydraulic jar intensifer is a kind of down hole fshing jar tool designed to increase jarring function for up jar. So it must be used together with super fshing jar. It could accelerate for the top end of jar and the drill collar connecting with its bottom end when working, so to get larger jarring force on stuck point, and reduce quake of drill stem springback after jarring at the same time.

Surface Bumper Jar
DXZ Surface bumper  jar  is a  tool releasing stuck for down hole tools on the wellhead, It applys to release stuck which needs downward jarring like keyslot, shrink neck, fall off block, sticking  to suck etc.  it also can relieve down hole fishing tools. When surface bumper jar is working on wellhead. No matter what parts of drill stems stuck, slips down hole tools stuck, fshing tools stuck or testing workover tools, well washing tools stuck, it all can use surface bumper jar to release stuck.DXZ Surface bumper jar is a new type full mechanical surface bumper jar, it overcomes previous defect of friction type's slips are easy to burn. adjusting is not exact, it can adjust jarring release force at any time, and easy exact stable to adjust.

Fishing Bumper Sub
KXZ Fishing bumper sub is a mechanical jarring tool. It can repeatedly jar for stuck drill stem, make stuck point loose and release, when lifting and jarring can not release stuck, it still can rotate to make releasing fshing tools release fshes. When fshing bumper sub works with mechanical  internal cutter,  it can make  internal cutter get preset constant forward force, to cut steadily. When it works with back off tools, it can compensate a rising stroke for connection after back off.

Mechanical Shock Absorber
JQ-DH shock absorber  is an absorbing  tool acting as vertical absorbing function when drilling with cone bits or abrasive coring bits. It can absorb or slow down vertical shocking and impact load of drill stem when drilling, thereby keep normal drilling pressure, prolong working life of drill bit, protect drilling tools and surface equipments, decrease drilling cost, increase drilling effciency. JQ-DH uses butterfy spring as elastic element,  it is different from hydraulic shock abscrber using silicon oil and other fluid as working medium, its working property doesn't be effected by working environment, this mechanical  type shock absorber is a new R&D tool made by our factory and a foreign company, it has the advantages of simple structure, reliable working, convenient operation and maintenance, good absorbing effect, long working life and high property, it’s one of the most widely used drilling tools oversea.
