| description | A wellbore isolation device includes a mandrel, a sealing element disposed around at least a portion of the mandrel, and a delay coating disposed on at least a portion of an outer surface of the sealing element. The sealing element includes a swellable material and the delay coating covers a cross-linked polymer. The delay coating is configured to swell or degrade in a wellbore fluid.
L'invention concerne un dispositif d'isolation de puits de forage qui comprend un mandrin, un élément d'étanchéité disposé autour d'au moins une partie du mandrin, et un revêtement retard disposé sur au moins une partie d'une surface extérieure de l'élément d'étanchéité. L'élément d'étanchéité comprend un matériau gonflable et le revêtement retard recouvre un polymère réticulé. Le revêtement retard est conçu pour gonfler ou se dégrader dans un fluide de puits de forage. |
