一种快速连接深水膨胀型表层导管
By triggering the self-expanding outer layer of the shape memory alloy ring to make close contact with the soil, and the inner metal bushing providing rigid support, the hydraulic support components absorb vibration, thus solving the problems of low connection efficiency and poor sealing performance of traditional deep-water surface conduit, and achieving stability and efficient operation of the wellhead structure.

AI Technical Summary
Traditional deepwater surface conduit has low connection efficiency, poor sealing performance, and weak resistance to lateral pressure, making it difficult to maintain wellhead structural stability in harsh environments.
The outer layer of the structure, which is triggered by a shape memory alloy ring, is in close contact with the soil. The inner metal bushing provides rigid support, and the hydraulic support absorbs vibration. Combined with the double sealing structure, it achieves rapid connection and reliable sealing.
It significantly improves the efficiency of deepwater drilling operations, enhances the lateral friction and bending resistance of the surface guide tube, ensures the stability of the wellhead structure, extends its service life, and reduces maintenance costs.
