Background:

Tunnel seismic data processing faces challenges due to small quantities, multi-component nature, and small offsets.
Traditional Kirchhoff migration, limited by ray theory and aperture, lacks the accuracy needed for high-precision tunnel imaging.

Purpose of the Study:

To analyze and compare the imaging accuracy of 3D Kirchhoff migration and 3D RTM using modeled and measured data.

Main Methods:

Utilizing the reverse-time recursion principle of the wave equation for cross-correlation imaging.
Applying 3D RTM to multi-component seismic data, overcoming small offset limitations.
Comparing single-component and multi-component Kirchhoff migration and RTM profiles.

Main Results:

3D RTM overcomes small offset effects, expanding migration imaging range.
Multi-component RTM improves anomalous interface energy and resolution.
Modeled and measured data validate the advantages of 3D multi-component RTM.

Conclusions:

3D RTM is the most accurate migration method for tunnel seismic data.
Multi-component RTM significantly enhances imaging resolution and energy compared to Kirchhoff migration.
The study confirms the superiority of 3D multi-component RTM for tunnel seismic applications.
