The 660W series packer is an industrial standard single-tube retrievable packer with hydraulic setting and shear release through tubing transmission. One or more can be lowered into the well together, and is particularly suitable for large-angle deviated wells or other wells that require no rotation, and is widely used in production, injection, interlayer isolation and other construction processes.

The packer does not require any mechanical operation on the production string. The packer is lowered to the required depth and a predetermined pressure is applied to shear the pins to set the packer. The bidirectional anchoring slip resists the forces from both the upper and lower directions to prevent the packer from moving upward.

Features:

• Simple and robust modular design
• Bidirectionalslips, effectively anchored in the casing
• Hydraulic interlocking system
• Shear release value can be adjusted on site
• Built-in unloading and bypass, easy to release and recover
• Bidirectionalslip system, eliminating the need for hydraulic anchors
