Protective barriers for small devices, such as sensors, actuators, flow control devices, among others, protect the devices from erosive and/or corrosive fluids, for example, formation fluids under harsh downhole conditions. The protective barriers include protective coatings and fluid diverting structures in the fluid flow which facilitate use of the small devices in high temperature-high pressure applications with erosive and/or corrosive fluids that are often found in downhole environments.

L'invention porte sur des barrières protectrices pour de petits dispositifs tels que des capteurs, des vérins, des débitmètres ou autres contre les fluides érodants et corrosifs tels que les fluides des formations, dans des conditions sévères de fond de puits. Lesdites barrières consistent en revêtements protecteurs et en structures déviant les fluides et permettant d'utiliser les petits dispositifs dans des systèmes fonctionnant à température et pression élevées et soumis aux fluides érodants et corrosifs souvent présents en fond de puits.
