3.Working principle

Set: 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 center pipe, thus the the slip ring moves along the track groove of the trajectory center 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.

4.Product Feature

Can be set in different steel grade casing stable and reliably.

The sealing mechanism is consist of two kinds of hardness elements.

Mechanical set, easy operate.
