DH-422 Retrievable Mechanical Packer

 

DH-422 Retrievable Mechanical Packer

 

Application

Apply for operation such as water plugging and fracturing in the oil field, it can also be used as

the bridge plug in the well.

 

        Feature

• The usage range of the tools and instruments on the packer is wider than  the

 

ordinary packer.

 

• There is no O-ring, preventing the packer invalidation because of the leak of the O-ring.

 

• Double grip supporting, the anchor state is stable, preventing the packer invalidation

 

because of the moving of the string. Meanwhile, the packer can work in either compression,

 

tensile or neutral state because of bidirectional anchor.

 

• One of the upper slips uses special teeth thread, makes the packer easy to be released.

 

• There's a emergency unlock device to ensure packer can be released successfully.
