Abstract
(EN) A fluid control device includes a support structure configured to be deployed in a borehole and a filtration component disposed at the support structure. The filtration component includes a porous medium made from a shape memory epoxy, the shape memory epoxy including a soft segment monomer and a hard segment monomer, the porous medium configured to be compacted from an initial shape to a compacted shape, deployed in the borehole, and subsequently expanded due to a downhole temperature to conform to a surface of the borehole.
(FR) Dispositif de commande de fluide comprenant une structure de support conçue pour être déployée dans un trou de forage et un composant de filtration disposé au niveau de la structure de support. Le composant de filtration comprend un milieu poreux fait d'un époxy à mémoire de forme, l'époxy à mémoire de forme comprenant un monomère à segment souple et un monomère à segment dur, le milieu poreux étant conçu pour être compacté d'une forme initiale à une forme compactée, déployé dans le trou de forage, puis expansé en raison d'une température de fond de trou pour se conformer à une surface du trou de forage.
