DST Tools Double Grip Retrievable Casing Packer from kingwell oilfield
Features
The double-grip packer, for use where pressure differential from below the
packer is anticipated, features an integral hydraulic button-type hold down
that is located below the bypass. It also incorporates a unique, built-in
"differential lock" which utilizes a balance sleeve actuated by pressure from
below the packer. This pressure creates an additional downward force
which, combined with set-down weight, helps maintain the force necessary
to keep the bypass valve closed.
• The packer parts are interchangeable with equipment from other
manufacturers, reducing costs and inventory.
• The large bypass enables fluids to equalize quickly and reduces the swabbing
effect during run-in and retrieval for faster running.
• The standard one-quarter right turn for packer setting provides simple
operation on the rig.
• A differential lock helps to keep the bypass to the mandrel closed and locked
during high-pressure operations to maintain integrity and prevent production
loss and the need for a workover to pull out of the hole and redress the packer.
• The long-stroke mandrel simplifies fluid circulation without packer release.
• The packer automatically returns to the run-in
