| Abstract: | Aiming at the special seismic and geological conditions of the loess plateau slope zone, the combined excitation mode of the slope zone is numerically simulated by using the spectral element method wave field simulation algorithm, the wave field characteristics are accurately reflected,and the multi-well combination excitation parameters are optimized theoretically. The numerical simulation agrees well with the experimental results. A high-density seismic wave excitation technology has been explored, and high-precision 3D seismic data have been obtained. |
