Y211 packer
It can be widely used for zonal injection,extraction,leakage detection,squeezing,acid treatment and well texting.

Working principle:

 

Lifting the string and then lowing it according to the setting height,the centralizing block is against the casing wall under the action of the spring. When lift the string, the centralizer part of the packer is relatively displaced with the trajectory of central pipe,thus the slip ring moves along the track groove of the trajectory central pipe,moves from the upper dead point to the top dead center, the grip opens along the cone and fastened on the casing wall. At the same time, the setting pin is cut off under the string gravity, the upper joint and the trajectory of the center pipe move down together, compress the seal, larger the diameter, thereby isolating oil, casing annular space 

 

Release: lift the string, the upper joint moves up, and the seal is released, the slip ring moves to the lower dead point, the cone exit from the slip thus the grip is released.

Structure:

 

As the above Fig. showed, Y211 packer is composed of anti-corrosion barrel in high temperature and pressure, whole central pipe, friction commutator and lower joint. The slip has been treated by carburizing and quenching. The rigidity of surface and toughness of center is very high, so it's not easy broken when conflicts with load. The barrel is above the slip to avoid covered by sand. The structure is simple and easy to operate. 

 

Characteristics:

 

a) It's sealed by pulling and lowering column. It's released by pulling the column.

 

b) It is supported by unidirectional slip. Sealing and unsealing are convenient and reliable. 

 

Feature: 1. It can be set in most kind of casing safely and reliably

       2. Three seal in two kinds of hardness makes a sealing system.
