The ALFZ-D hydraulic-opening stage cementer features inner closing structure,opening by differential pressure. The closing plug drives the closing sleevedown and then shuts off circulating ports.

Features

1.Opening pressure can be adjusted and it is not affected by the hole angle or mudproperties for operation.

2. Thepressure-relief design prevents fluid trapping and compression during theclosing phase of the tool's operation.

3. TheI.D. of upper/lower sub is the same as that of casing, but smaller than that ofclosing sleeve, which can minimize chances of damages to the closingsleeve.

4. Theinner seats are made of an easily drillable butyronitrile rubber/aluminummaterial. Both the opening and closing seats lock against rotation for easydrillout.
