Mechanical Drilling Jar
The mechanical drilling jar type JZ takes the appliance of mechanical structure And high pressure will not produce in inner chamber as to create a good sealing property and greatly extend the service life During the drilling operation, the jarring mechanism has no action due to its unique structure which can not be controlled by the common drilling condition and torque, and its unique structure can accurately transmit the torque Moreover, the up or down jarring blow is adjustable prior to tripping in and will not change during the downhole operation so as to keep a constant jarring load

Full Hydraulic Drilling Jar
The full hydraulic drilling jar type QY is a double-acting hydraulic jar and is used to free equipment stuck down hole It can be used with a down hole motor, because it is capable of torque transmission, and is ideal for use in coiled tubing operations, snubbing, rotary drilling and fishing applications By adjusting the amount of surface push or pull (no torque or external adjustments are required) the operator can deliver very light or maximum impacts in either direction

Hydro-mechanical Drilling Jar
The hydro mechanical drilling jar type ZXJ can be used either independently or in conjunction It is designed for use during drilling operations to apply an intensified force either up or down against a stuck portion of the drilling string Its unique design combines both a hydraulic time delay release and a mechanical latch mechanism, in one relatively short, double acting drilling jar Therefore, it is an ideal tool for drilling directional well, complicated well and slant well
