Y211 Type Packer

Y211 Type Packer

※ Brief Introduction
This packer is suitable for layered oil testing, oil production, water finding, water plugging, fracturing, acidification, sand control and other processes.

※ Working Principle
Setting: When the packer is lowered into the well, the centralizing slip, under the action of the spring, makes the centralizing block tightly adhere to the inner wall of the pipe, and the trajectory pin is at the dead center of the short track. After reaching the predetermined position, lift the pipe column up to a certain height and slide the trajectory pin to the dead center below the short track. At this point, lower the pipe column again and slide the trajectory pin to the long track. So, the kava was stretched open by the cone and secured to the inner wall of the casing. Continue to lower the compression rubber cylinder to seal the oil and casing annulus.

Unpacking: Lift the oil pipe column up, the cone exits the slip, and the trajectory pin slides to the dead center under the long track, then the packer can be lifted out.
