Detailed
The full hydraulic drilling jar type QYis 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.
