Jars
Hydraulic drilling jar integrates upward jarring with downward jarring. It is a hydraulic type drilling jar, which is used in all kirds of well conditicn, it generates up and down jarring force by lifting and releasing drill stems when the drilling tools were stuck and make sure drilling operation can go smoothly.

Double Acting Mechanical-Hydraulic Drilling Jar
Double acting mechanical-hydraulic drilling jar integrates upward jarring with downward jarring and has all advantages of both mechanical drilling jar and hydraulic drilling jar, it applies to all kinds of drilling operations and be used through combining with drilling tools.

Mechanical drilling jar is a full mechanical type drilling jar and releasing stuck tool. It integrates upward jarring with downward jarring releases the tight pull or the sticking or other drilling troubles during drilling. It is a part of drill stem when it needn't jarring and it can work at anytime when need jarring.

Double Acting Drilling Accelerator
The double acting drilling intensifier is a downhole drilling tool to enhance jarring function for the full hydraulic drilling jar, so it must be used with the full hydraulic drilling jar together.
