Actuatable sealing mechanism for fluid channels in tubular members
The granted patent US12044093B2 introduces an actuatable sealing mechanism designed to effectively seal a fluid channel situated between two co-axially arranged tubular members. This mechanism features an elastomeric seal with a convex sealing surface, an axially moveable actuating sleeve, and a radially moveable activating member. The mechanism operates by transitioning between an unsealed state, where the elastomeric seal remains uncompressed, and a sealed state, where the activating member moves the actuating sleeve to compress the elastomeric seal, expanding it radially to create a seal against the opposing tubular member. The design allows for the elastomeric seal to return to its original shape when the activating member is moved back, ensuring a reliable sealing function.
Additionally, the patent outlines various configurations and functionalities of the sealing mechanism, including the arrangement of the elastomeric seal and actuating sleeve in a ring shape, which allows for uniform sealing around the annulus. The mechanism can be integrated into drilling operations through an integration joint assembly, which connects to a riser system and accommodates a tubular work string. The sealing device within this assembly is capable of selectively sealing the fluid channel, enhancing the efficiency and safety of drilling operations. The patent also describes methods for sealing both the fluid channel and the annular space between inner and outer pipes, emphasizing the versatility and applicability of the actuatable sealing mechanism in various industrial contexts.
