AI Technical Summary
The lack of existing technologies for simultaneously designing irregular excitation and receiving points makes it difficult to maintain the sparsity of excitation or receiving points during seismic acquisition, thus affecting the quality of seismic imaging.
By determining the grid size and layout coordinates of two types of seismic physical points, the work area is divided using a global grid size, and the coordinates of un-deployed seismic physical points are determined in the grid, thereby achieving the joint irregular layout of excitation and reception points and optimizing the distribution of seismic physical points.
This achieves a more uniform distribution of excitation and receiver points, reduces correlation, improves the spatial image reconstruction quality of seismic imaging, and enhances image generation quality while maintaining the signal-to-noise ratio.
