HIGH TEMPERATURE ISOLATION PACKER

The high temperature isolation packer is a high performance recyclable sand control packer that is used  primarily for interlayer isolation in stratified Wells, as well as for general interlayer isolation or stuck zones.

The pressure is transferred to the piston in the piston chamber through the pressure in the tubing, and  the piston pushes the internal locking ring forward to move the compression rubber barrel to seal, and  the oil casing annulus can isolate each section.

Note: Other specification products are available.
