4.Model "JYQ" Hydro-mechanical Drilling Jar
GENERAL
Model "JYQ" Hydro-mechanical Drilling Jar is a double-action drilling tool used to free the stuck tools and make a jarring. It integrates the up jar and down jar and can deal with the stuck accident happened in shortest time during the drilling. It is an ideal jarring tool for the directional well and deep well.
Operators can make an adjustment for lifting and lowering drill tool (without the adjustment of torque and outside) to get the releasing up jar or down jar force when used the Drilling Jar downhole. Moreover, the operator can adjust the jarring force from small to maximal force required. It can be broadly used for drilling, coring, fishing and workover because of its easy operation, convenience and high reliability
Product detail:
Repeat above-stated procedures as to produce a continuous up jarring motion. Maximum up jarring releasing load is different under various hydraulic pressure drop of bit (See Table 5-1). So, maximum up jarring releasing load can be decided by hydraulic pressure drop on bit.
