Title (EN) WELLBORE SEALS WITH COMPLEX FEATURES THROUGH ADDITIVE MANUFACTURING
(FR) JOINTS D'ÉTANCHÉITÉ DE PUITS DE FORAGE POURVUS DE FORMES COMPLEXES OBTENUES PAR FABRICATION ADDITIVE
Abstract:
(EN) A wellbore sealing device having an elastomeric element with complex features and associated additive manufacturing method is disclosed. The complex features can include voids such as isolated voids and undercut-like voids that cannot be reasonably produced using existing molding techniques (e.g., due physically impossible mold shapes or cost- prohibitive mold requirements). These complex features can alleviate stress and increase radial expansion of the elastomeric element in response to axial compression of the elastomeric element. Such elastomeric elements with complex features can be additively manufactured (e.g., through three dimensional printing). In some cases, the elastomeric elements can be additively manufactured directly on a tool, such as on an end plate or mandrel of a wellbore sealing device.
(FR) L'invention concerne un dispositif d'étanchéité de puits de forage comportant un élément élastomère pourvu de formes complexes, et un procédé de fabrication additive associé. Les formes complexes peuvent être des vides, tels que des vides isolés et des vides de type évidements qui ne peuvent pas être raisonnablement produites à l'aide des techniques de moulage existantes (par exemple, en raison de formes de moules complexes ou d'exigences de moules au coût prohibitif). Ces élémentformes complexes peuvent atténuer la tension et augmenter la dilatation radiale de l'élément élastomère en réponse à la compression axiale de ce dernier. De tels éléments élastomères pourvus de formes complexes peuvent être obtenus par fabrication additive (par exemple, par impression tridimensionnelle). Dans certains cas, les éléments élastomères peuvent être obtenus par fabrication additive directement sur un outil, tel que sur une plaque d'extrémité ou un mandrin d'un dispositif d'étanchéité de puits de forage.
