DH-221M Retrievable Mechanical Packer

Application：

Apply for zonal injection, extraction, leak finding, squeeze, acid treatment and well testing.

       Feature：

• Hydraulic anchor use stainless steel materials, which effectively prevent the phenomenon hydraulic anchor claw rust and not back happened because of long time, poor water quality in the sealing process.

• The elements are made of import modified hydrogenated butadiene acrylonitrile rubber vulcanization, which has the characteristics: high temperature resistance, anti-aging, resistance to high pressure difference. Once uncured after a long time in seal compression, the recovery is good.

• Anchor claw and slip are set with hard alloy, which increased the bite of casing ability; it is suitable for different styles.

• Slip and slip bowl are combined with wedge, which makes set or unsealing easy..

• Center tube is designed with internal the sand controls scream so that it is easy to be recovery.

The design of packer is scientific; Production processing technology is controlled strictly,good performance characteristics.
