AI Technical Summary
Existing technologies have low computational efficiency in seismic data reconstruction and insufficient reconstruction accuracy for irregular data, which cannot meet the high-precision processing requirements of complex seismic wavefields and weak energy seismic signals.
The gather data of each pre-collected shot point is divided into multiple three-dimensional data volumes, and three-dimensional curvelet transform is performed in parallel. An iterative threshold function is constructed, and the reconstructed data is obtained through iteration and inverse transform. The signal-to-noise ratio and root mean square amplitude are used to determine the end of the reconstruction.
It improves computational efficiency, enhances the quality and accuracy of reconstructed data, ensures that the amplitude of the reconstructed data is not distorted, and meets the high-precision requirements of seismic data processing.
