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.
