Hydraulic jar (up / down) designed to use accelerator and flow sub form a coiled tubing short heavy string. The Jar delay device let the energy stored in the stretched and elongated string accelerator, when the energy released will have a great impact, generating shock effect, loose card tool stuck.
Up jarring
Lowering drill string to make drilling jar closed completely (in locking position), elevating drill string by the order of small tonnage to larger tonnage, which make spring and hydraulic cylinder delay, when mandrel move to a position and become release resistance, the spring force stored in drill string will transfer to upforward energy and up jarring. Repeating the above several times can force tool to produce continues up jarring.
Down jarring
Move up and down the drill string to make drilling jar closed completely (in locking position), lowering drill string to make spring compressed and stored energy. When pressure of jar is larger than the desired lower unlocking force, grapple will slide out from mandrel to release the locking and make down jarring. Repeating the above several times can force tool to produce continues down jarring.
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.

JYQ Double Acting Hydraulic-Mechanical Drilling Jar 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. Upon the request, the tool can automatically control the impact strength and times of jarring. It is an ideal tool for vertical well and deflecting well.
