A stage cementing tool for use in cementing a casing in the well is disclosed. The stage cementing tool include housing with a mechanically set packer to seal against the well. A hydraulically actuated opening sleeve will move in the housing to uncover flow parts in the housing and allow flow there through into the well.
1. Opening pressure can be adjusted and it is not subjective to hole angle.
2. The pressure-relief design prevents fluid trapping and compression during the closing phase of the tool's operation.
3. The I.D of upper/lower sub is the same as that of casing, but smaller than that of closing sleeve, which can minimize chances of damages to the closing sleeve.
4. The inner seats are made of an easily drillable butyronitrile rubber / aluminum material. Both the opening and closing seats lock against rotation for easy drill-out.
