Y211 packer belongs to the mechanical setting of slip packer, which uses the method of lifting up and lowering the pipe string to set and lifting up the pipe string to unseal. It has the advantages of smooth lifting and lowering, no wrong sealing in the middle, simple sealing and unsealing operation, reliable sealing, high pressure bearing, large diameter, and low friction. It is mainly used in oil testing, water finding, and channeling inspection operations.

Features/Advantages

Combined with hydraulic anchors and reverse circulation valves, it can be used for hydraulic fracturing operations

Short length, good passability

Reliable sealing system that can withstand up and down pressure differences during operation
