This drilling jar is used to release the stuck during drilling operation. When it is inactive it is just a part of drill string; when needed it is able to be activated to provide shocking force and improve the drilling efficiency.

Product Features
- Wide adjustable shocking force range. The upper and lower shocking forces of our drilling jar are adjustable and our drilling jar provides a wide adjustable shocking force range.
- Complete mechanical design makes the drilling jar more reliable.
- No high pressure in internal cavity makes the sealing more reliable and shocking force is not affected by the oil quality.
- Specially designed flexible joint decreases the bending stress produced by the drilling jar itself.
- Adopted new type special material improves the product performance greatly
- Well applicable. Our drilling jar is applicable to the vertical well, deep well, complete well and directional well.
