Title
(EN) INSULATING FLUIDS CONTAINING POROUS MEDIA
(FR) FLUIDES ISOLANTS CONTENANT DES MILIEUX POREUX
Abstract
(EN)
Insulating fluids for use in drilling, production, and other applications are provided, the insulating fluids containing a porous medium (such as a sponge or foam) to limit the mobility of the liquid phase of the insulating fluid. The porous medium in the insulating fluid provides a mechanical means for reducing convective heat transfer, as the small pore spaces within the porous media create tortuous paths for the liquid moving therethrough. Methods include introducing the insulating fluid into an annulus of a drilling, riser, production, packer, or pipeline assembly to reduce heat transfer therethrough.
(FR)
L'invention concerne des fluides isolants destinés à être utilisés en forage, en production et autres applications, les fluides isolants contenant un milieu poreux (tel qu'une éponge ou une mousse) pour limiter la mobilité de la phase liquide du fluide isolant. Le milieu poreux présent dans le fluide isolant fournit un moyen mécanique pour la réduction du transfert de chaleur par convection, du fait que les petits espaces de pores à l'intérieur du milieu poreux créent des trajets tortueux pour le liquide se déplaçant à travers eux. Des procédés comprennent l'introduction du fluide isolant dans un espace annulaire d'un ensemble de forage, colonne montante, de production, garniture d'étanchéité ou pipeline pour réduire le transfert de chaleur à travers lui.
