Super Fishing Jar Type CSJ
The super fishing jar type CSJ is a up jarring tool that utilizes a core piston to realize the jarring action. The down hole jarring blow is adjustable without any rig floor adjustments necessary prior to the run. Impact of each blow can be varied by simply changing the pull load.

Mechanical Drilling Jar Type JZ
The mechanical drilling jar type "JZ" takes the appliance of mechanical structure. And high pressure will not produce in inner chamber as to create a good sealing property and greatly extend the service life. During the drilling operation, the jarring mechanism has no action due to its unique structure which can not be controlled by the common...
Double-acting Mechanical-hydraulic Drilling Jar Type JYQ
The double acting mechanical-hydraulic drilling jar type jyq is designed for drilling operation to apply an intensified force either up or down against a stuck portion of the drilling string. It incorporates the feature of both hydraulic and mechanical drilling jars, without of the inherent disadvantage of either type. Its unique design combines...
Integral Mechanical Drilling Jar Type JSZ
The integral mechanical drilling jar type "JSZ" is a double-acting mechanical drilling jar. The down hole jarring blow is not adjustable in the down hole (only can be adjusted in the pipe yard ). It is the shortest drilling jar, and can self-lock in drilling operation.

Mechanical Fishing Jar Type JSQ
The mechanical fishing jar type "JSQ" is a up jarring tool for releasing sticking that adopts mechanical friction principle. Installed close to the fish in the fishing operation, it can deliver an intensive jarring impact upward on the fish directly. The jarring blow is pre-adjusted prior to the
run.

Hydraulic Fishing Jar Type Z
The Hydraulic Fishing Jar type "Z" is a up jarring tool that utilizes the drill tool�s elastic potential energy resulted from the elastic deformation to realize the jarring action. It is used for fishing, coring, reaming, and side tracking. When used in combination with the jar intensifier type "YJQ",
it can generate better jarring...
Mechanical Fishing Jar Type JS
The mechanical fishing jar type "JS" is a up jarring tool that is installed close to the fish in the fishing operation. The down hole jarring blow is adjustable without any rig floor adjustments necessary prior to the run. The tool can work in high temperature or high pressure deep well, even if the seals are damaged, it can still continue to...
Hydraulic Shock Sub Type YJ
The Hydraulic Shock Sub type "YJ" is fully hydraulic and is used for reducing vibrations caused by hard formation drilling and keeping the drill bit firmly on the bottom, so that it helps to reduce drill string connection fatigue and prolong drill string life.

Two-way Shock Sub Type SJ
The two-way shock sub type "SJ" is an effective shock absorbing device. It can be used to reduce or eliminate both transversal and longitudinal vibration of drill string, thus it helps maintain normal weight-on-bit (WOB) and torque, so that it helps to reduce drill string connection fatigue and prolong drill string life.

Mechanical Hydraulic Shock Sub Type DHJ
The mechanical and hydraulic shock sub type "DHJ" is a two-function shock sub that absorbs the pulsate and shock from drill tools by dish spring and hydraulic oil to store the energy. It is used for reducing vibrations caused by hard formation drilling and keeping the drill bit firmly on the bottom, so that it helps to reduce drill string...
