Team 2302: Letter from October 28. Due to our limited level and lack of understanding of the specific circumstances, it is very difficult for you to make any specific comments. The following crude view, only for your reference. Wrong place, please criticize correction. The seismic geological conditions in your work area are rather complicated. The fourth to third instars are undisplaceable and loose, which will cause more serious interference. Second, the bottom line of the Tertiary is a clear demarcation of the density and velocity, so multiple waves (when the interface is smooth) or severe scattering may be generated (when the interface is rough) that obscures the reflection of the underlying formation. Again, from the explanation
