DOH naked eye packer is a hydraulic permanent packer that, with its special rubber cylinder component and reliable design, can withstand a pressure difference of 10000psi in naked eye wells. This packer is designed specifically for naked eye fracturing packer systems and can be used for multi-stage packer in fracturing packer systems. It can also be used for casing sealing.

Features/Advantages

The one-way locking ring maintains the sealing load and can continue to seal even under pressure changes

The rubber cylinder structure with metal protection forms a reliable sealing system

Sealing does not require reciprocating motion or rotation

Once the seat is locked, it cannot be unlocked

Unique mid way anti sitting sealing mechanism ensures smooth placement of the pipe column

The maximum working pressure is 70MPa (10000psi)

Conventional rubber cylinders and seals are recommended to be suitable for temperatures below 148 ℃ (300 ° F), and can be customized for higher temperatures
