Two features:
The pipe string is lifted up and lowered for sealing, and the lifting method is used for unsealing. The operation process is simple.
Using single slip support, the seat seal is flexible and reliable.
Using high-temperature rubber cartridges, used in conjunction with hydraulic anchors, it can perform fracturing and other processes.
Three usage methods:
Sealing: When going down the well, the control pin is on the short track. When the packer is lowered to the predetermined position, lift the pipe string to a certain height, and then lower the pipe string to make the pin change. To the long track, the slips are opened and stuck on the inner wall of the casing, compressing the rubber barrel to complete the seat sealing.
Unsealing: Lift up the tubing string and the rubber cartridge slips back into place, and the packer is unsealed.
