| Research on High-precision Processing and Imaging Technology of 3D Seismic Data in Coalfields |
| As a key technology for fine detection of coal geological structure and coal seam occurrence, 3D seismic exploration plays an important role in coal exploration and development and safe production. To solve the problem of conventional seismic data processing methods having limited imaging accuracy and resolution for complex geological structures, high-precision 3D seismic processing and imaging technologies in coal fields are investigated in this paper. The signal-to-noise ratio and resolution of seismic data are effectively improved by integrating multi-domain and multi-method denoising, maximum likelihood prediction filtering, combined deconvolution, high-precision residual statics, 3D data regularization, and bidirectional extension frequency. The bending ray Kirchhoff prestack time migration technique is used to obtain a high-precision time-domain imaging profile, which significantly improves the resolution of seismic signals and the imaging accuracy of geological anomalies. The method proposed in this paper provides an effective technical means for the fine processing and imaging of 3D seismic data in coalfields and plays an important supporting role in ensuring the safe mining of coal resources. |
