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