| 发明名称 | Shape memory seal assembly | ||
| 摘要 | A sealing assembly including a seal element at least partially formed from a shape memory material. The shape memory material urges the seal element to revert to an original shape upon exposure to a transition stimulus. The seal element is operatively arranged for sealing against a downhole structure when in the original shape. An interlock mechanism is included for holding the seal element in a deformed position in which the seal element is not able to seal against the downhole structure even after exposure to the transition stimulus. A method of setting a downhole sealing assembly is also included. | ||

| 主权项 | 1. A sealing assembly comprising: a seal element at least partially formed from a shape memory material, the shape memory material urging the seal element to revert to an original shape upon exposure to a transition stimulus, the seal element operatively arranged for sealing against a downhole structure when in the original shape; and a mechanical interlock mechanism for holding the seal element in a deformed position in which the seal element is not able to seal against the downhole structure even after exposure to the transition stimulus, the interlock mechanism being actuated independently of seal element energy. | ||
