4.Working Principle

●Set: Landing the packer to the reserved position in the well, pressure out in tubing, the piston moves up, and the pin is cut off, then the lock sets move up and the element is compressed. At the same time, the lock set and lock ring lock each other, so that the element can not be recycled. During the process, seal the tubing annulus, the setting is completed.

●Release: Lift the string, cut off the pin with the friction between element and the casing, the lock ring is without limit. The lock ring and lock set move down and release the stuck under the element back stretch, and the packer is released.

●Wash well: Increase pressure by 0.5 MPa to wash the well.

5.Product Feature

●Double-piston, low-pressure set explored, good sealing.

●Highly temperature-resistance and pressure-resistance glue tubing explored, stable, widely used.

●Reasonable-design, high-pressure, overturn well-flushing with large emission.

●Straight pull release, easy to operate and stable.

●According to customer's requirement to add backflushing.
