Tool Introduction

Y341 backwashable well packer is a hydraulic compression unsupported packer used for lifting and releasing oil pipes, mainly for water injection.

Structural characteristics

① Easy to operate, hydraulic seat sealing, lifting and shearing to unlock;

② During the sealing process, there is no movement of the central column, making it suitable for combination use;

③ The packer has reliable performance, simple structure, and easy operation.

operation

Adopting hydraulic propulsion to connect the two-stage piston compression rubber cylinder for sealing, while mechanically locking and preventing retreat. When the well needs to be washed, the oil ring annulus can be pressurized to open the well washing valve, achieving the well washing function. When injecting water, the pressure inside the tubing is higher than the casing pressure, the flushing valve is closed, and the layers are separated to achieve layered water injection. Directly lift the pipe column to unseal.
