MECHANICAL SETTING RETRIEVABLE PACKER
The packer is retrievable packer with double-grip and it can be set with tension or compression and holds pressure
from above or below the packer.Once setting, the downhole string can be left in tension, compression or neutral.
A large internal bypass can reduce the packer swabbing effect during running and retrieving, and will be closed when
the packer is set.
Internal bypass can reduce swabbing effect.
*Can hold differential pressure from upper and lower.
*Only need one-fourth turn right-hand rotation to set and release.
*String can be left in tension,compression or neutral while packer in setting state.
*If needed,can use alternative shear release method for emergency release .
*Aim at the hostile environment,can choose different packing element.
*Bypass valve is below the upper slip,so the debris is washed from slips when the valve is opened.
*Normal working temperature:300°F,normal working pressure:10,000psi[70MPa].
