4.Working Principle

●Set: Put the packer into the designed well position, Within the tubing pressure-out, the piston is upper, the piston upward cut setting shear pin, put the slips upward, making the single slip input the hydraulic pressure through the oil tube , after the hydraulic pressure incomes the hydraulic cylinder of packer , driven by the piston downward making the slips open and anchoring on the casing tube . At the same time, the upper position lock block are set off, the hydraulic pressure put( promote) the upper position upside , compressed rubber tube ( packer rubber) , closed oil casing and annulus .After release the pressure, locked well the locking mechanism, in case the sealing part recovery.

●Release: Lifting the pipe string , anchoring mechanism don't move , the center pipe along with pipe string is upward, cut off the unlock shearing ,release the unlock lock block, the rubber tube is released, upwards again, lifting the upper cone ,the packer slips are out of the tube ,finished the packer unlocking .

5.Product Feature

●Bi-directional slip grappling, holds high pressure differentials from above or below.

●Tubing pressure actuated, straight pull release, suitable for deviated wells, straight wells, shallow wells.
