The surface of the loess mountain area in southern Ordos is covered by a thick loess layer, and the seismic exploration process has poor excitation and reception effects of seismic waves, and the reflection energy of seismic waves in the target horizon is weak, and the quality of collected data is poor. According to the principle that high water saturation and good lithology of loess layer will be beneficial to seismic wave excitation, through the investigation of water saturation and lithology of loess layer in the study area, the best seismic wave excitation horizon and depth are determined, and the best single well excitation dose is determined according to practical experience. In the aspect of seismic wave receiving and recording, the basic flow of survey line layout is worked out, and the seismic wave acquisition scheme suitable for the study area is finally worked out by combining the seismic wave receiving scheme with small path distance, large offset distance and high coverage times.
