Abstract

L'invention concerne une surface barrière pour composants élastomères de fond de trou. Dans un mode de réalisation, un composant élastomère pour utilisation fond de trou, tel qu'un joint d'étanchéité destiné à une pompe submersible électrique (ESP), est composé d'un matériau de base élastomère perfluoré protégé par une couche de surface barrière composée d'un fluoropolymère ou d'un polyaryléthercétone, afin d'isoler la base élastomère perfluorée des fluides de forage haute température et chimiquement agressifs. Cette couche de surface barrière augmente la durée de vie utile du composant élastomère en empêchant l'hydratation à haute température des réticulations polymères dans le matériau de base élastomère perfluoré sous-jacent, et en augmentant le pouvoir lubrifiant de la surface extérieure. Un agent de blocage, tel qu'une argile à l'échelle nanométrique, du noir de carbone, du talc, du mica, de la silice,du graphène, des nanoplaquettes de graphite, des particules métalliques ou des nanoparticules métalliques, peut également être ajouté à la couche de surface barrière afin d'armer encore plus la surface barrière contre les fluides de forage.
