Title (EN) DOWNHOLE TOOL CONSISTENT FLUID CONTROL
(FR) COMMANDE DE FLUIDE COMPATIBLE AVEC UN OUTIL DE FOND
Abstract: front page image
(EN)A downhole apparatus for use in a wellbore includes a housing having at least one passage or cavity capable of receiving a fluid. The downhole apparatus further includes an orifice in fluid communication with the passage or cavity. A viscosity-altering member is positioned in proximity to the orifice and is capable of being activated to change the viscosity of the fluid and thus a rate at which the fluid is able to pass through the orifice.
(FR)La présente invention concerne un appareil de fond à utiliser dans un puits de forage, qui comprend un logement ayant au moins un passage ou une cavité capable de recevoir un fluide. L'appareil de fond comporte en outre un orifice en communication du point de vue des fluides avec le passage ou la cavité. Un élément de modification de viscosité est positionné à proximité de l'orifice et peut être activé pour changer la viscosité du fluide et donc un débit auquel le fluide peut passer à travers l'orifice.
