The 337W series packer is a completion tool designed for hanging large-diameter casing. The packer is set by pressurizing the tubing. The delivery tool of the packer comes with a ball seat. There are two ways to release the delivery tool: one is to release the pipe by rotating the pipe column; the other is to cut the mandrel of the release tool and then lift the pipe column, and remove all the setting tools.

The permanent large-diameter hanging packer is lowered to the required depth, and a predetermined pressure is applied to shear the pin to set the packer. The bidirectional anchoring slip design can resist the forces from both the upper and lower directions, effectively preventing the upward movement of the packer.
