Description

Technical Field

[0001] This invention relates to the field of sonic logging pipe construction technology, and more specifically to an enhanced connection device and method for achieving long-term sealing of sonic logging pipe joints. Background Technology

[0002] Currently, the main connection technologies for sonic logging pipes include welding, threaded connections, rubber sleeve connections, multi-stage sealing structures, flange butt joints, and PVC heat shrink tubing. Among these, welding connections offer strong and durable connections, but produce numerous weld slag burrs, leading to unevenness within the pipe. Threaded connections rely on proper alignment for sealing and are prone to loosening and leakage. Rubber sleeve connections have low strength and are susceptible to detachment due to thermal deformation. Multi-stage sealing structures are complex and costly. Flange butt joints require bolt tightening, resulting in slower installation and higher costs. PVC heat shrink tubing requires specialized heating tools and is also expensive. These technologies primarily rely on the inherent sealing properties of the pipe material itself, lacking a convenient and reliable connection device and method. Summary of the Invention

[0005] Preferably, the sealing tape is a waterproof butyl tape.

[0006] Preferably, the width of the sealing tape is 10cm.

[0007] Preferably, the sealing range of the sealing tape is 30cm, extending from the center of the acoustic tube joint to 15cm on each side.

[0009] An enhanced connection method for achieving long-term sealing of sonic logging pipe joints, utilizing the aforementioned enhanced connection device for achieving long-term sealing of sonic logging pipe joints, includes the following steps: S1, Sonic logging pipe section cutting: Configure sonic logging pipes according to the length of the wall; S2, sonic logging pipe connection: After the sonic logging pipes are matched, they are connected according to the length of each single pipe. The sonic logging pipe joints are fastened with special hydraulic clamps. S3, Sealing of sonic logging pipe joints: After the sonic logging pipes are connected, seal the joints with sealing tape. S4, Installation of sonic logging pipes: After the sonic logging pipes are connected according to the length of the ground wall, the steel cage is installed. The processing of the ground wall steel cage is divided into three steps: binding of the lower row of steel bars, binding of the truss, and binding of the upper row of steel bars. The sonic logging pipes are installed and fixed after the truss binding is completed.

[0010] Preferably, in S1, the length of the ground wall is 33m, and 4 sonic logging pipes are installed in each section of the ground wall, requiring a total of 24 sonic logging pipes. The configuration of each section is: bottom pipe + middle pipe + top pipe = 6 + 4 6+3.
