DH-221M Retrievable Mechanical Packer Application： Apply for zonal injection,Website:http://www.dhpetrotools.com, 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.
