1. Mechanical drilling jar

Type JZ

This full mechanical drilling jar offers mechanical jarring in both directions. The load scope of the up jarring and the

down jarring is wide, which can be adjusted in maintenance

station or in site according to the requirement. The special

flexible extended shaft can cut down the flexural stress of

the jar body efficiently, so it is the most suitable drilling jar for vertical well, deep well, complicated well and directional well operations.

Type JSZ

Mechanical Drilling Jar Type JSZ integrates the up jarring with the down jarring. It can reduce the harmfulness of the flexural stress in downhole operation, so it is more safe and reliable, superior in offshore drilling and directional drilling.

2. Hydraulic drilling jar

   This integral hydraulic jar provide up jarring and

down jarring. When downhole drilling tools are

stuck, the jar can provide a huge impact to release

the tools, thus the drilling operation can be

continued quickly.

    The jar can be operated easily and conveniently

with high reliability and applied to many downhole

activities of drilling, coring, fishing, workover etc.

3. Double acting hydraulic-mechanical drilling jar

This is a jarring and stuck releasing tool. It integrates the up jar and down jar impact and can release the stuck occurred during drilling operation. According to the requirement, the tool can automatically control the impact strength and times of jarring. It is an ideal tool for vertical drilling and deflecting drilling.
