Drilling Jar

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 so wide that it 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 first selected 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, 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. Hydraulic Drilling Jar Type QY Hydraulic Drilling Jar Type QY is an integral hydraulic jar with up jarring and down jarring. When downhole drilling tools are stuck, the jar can provide a huge impact to unfreeze with up jarring or down jarring, thus normal drilling operation can be recovered quickly. When the jar is used, operators can adjust to picking up it or slacking off it on surface to create up jarring impact or down jarring impact(without addition to the torque or adjustment to the outside part)and adjust impact from very small range to the biggest range needed. The jar can be operated easily and conveniently with high reliability and applied to many downhole activities of drilling, coring, fishing, workover etc. Double Acting Hydraulic-Mechanical Drilling Jar Type JYQ This is a jarring and stuck releasing tool. It integrates the up jar and down jar impact and can release the stuck accident occurring during drilling operation. According to the requirement, the tool can automatically control the impact strength and times of jarring. Moreover, it is an ideal tool for vertical well and deflecting well.
