QYZ HYDRAULIC DRILLING JAR
In normal drilling operation, downhole drilling tools assembly was stuck sometimes due to many kinds reason, and drilling jar is an effective tool for releasing stuck. QYZ type hydraulic drilling jar integrate upward jarring with downward jarring, It can start drilling jar by lifting and releasing drill stem when drilling tools were stuck, so it will generate up and down jarring force, and make sure drilling operation can go smoothly. This type drilling jar has some advantages like easy operation、stable property、safety and reliable、easy maintenance etc.
YJZ HYDRAULIC-MECHANICAL DRILLING JAR
YJZ type hydraulic and mechanical drilling jar is integrate hydraulic principle with mechanical principle and 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.
SJYZ 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.
BZ MECHANICAL DRILLING JAR
Mechanical drilling jar is full mechanical type drilling jar and releasing stuck tool. It integrates upward jarring with downward jarring so that it can release drilling tools from the block or the stuck etc. during drilling. It is a part of drill stem when it doesn’t jarring and it can work at any time when need jarring, thus it is highly improve the drilling efficiency, it has widely load (jarring force) scope of upward jarring and download jarring, so it can be adjusted at the maintenance station or on the well site according to the requirement. The special flexible joint can effectively reduce the flexural stress of the drilling jar body. Therefore, it is the first selected drilling jar for vertical well, deep well, directional well and complicated well operations.
SZJS DOUBLE ACTING DRILLING ACCELERATOR
The double acting drilling intensifier is a downhole drilling tool to enhance jarring function for the full hydraulic drilling jar, so it must be used with the full hydraulic drilling jar together. It has hydraulic spring as the energy storage element and the structure design itself has no jarring function. The double acting drilling jar can intensify the drill collar and drilling jar which are connected under it to get more stronger jarring force, meanwhile it can reduce destroy for the drilling tools on the upper side of the intensifier during the upward or downward jarring operation.
JQ-JY MECHANICAL-HYDRAULIC SHOCK SUB
JQ-JY mechanical-hydraulic shock absorber is a new type double acting shock absorber, it absorbs jumping and shaking of drilling tools through compressed energy storage from two kinds of damping elastic elements which are disc spring and silicone oil, it has advantages of good maintainability, high load resistance and long service life etc. It can suit to different formation and provide the best protection for drill bits and drilling tools, and High temperature products (180oC) can also be provided according to user’s requirement.
JQ-YS DOUBLE WAY HYDRAULIC SHOCK SUB
JQ-YS double way hydraulic shock absorber is a kind of shock absorber which can slow down or eliminate shock both in vertical and axial direction. This tool can keep the normal bit pressure and torque, therefore it can reduce the damage of drill bit, drilling tools and ground equipment due to shock, to achieve the purpose of improving drilling rate and reducing the drilling costs.
JZY HYDRAULIC SHOCK SUB
JZY hydraulic shock absorber can use its inner compressible liquid to absorb or reduce impact and shock load on drill bit and drilling tools when drilling, so it is a kind of tool which can protect drill bit teeth, bearings and drilling tools, to prolong the service life of drill bit and drilling tools.
JZ MECHANICAL SHOCK SUB
JZ shock absorber is a shock tool act as vertical absorbing function when drilling with cone bit or abrasive coring bit. It can absorb or slow down vertical shocking and impact load of drill stem when drilling, thereby keep normal drilling pressure, prolong service life of drill bit、protect drilling tools and surface equipment、decrease drilling cost、increase drilling efficiency.
