| Abstract: | The uneven loess cover thickness and great difference of seismic wave velocity in the loess table area of Qinshui Basin have significant influence on the excitation of seismic exploration. In view of the characteristics of regional surface strata, the seismic geological modeling is designed to analyze the forward records of different excitation horizons. Combined with the field tests, the forward modeling records are compared and analyzed. The results show that the reasonable excitation horizon can effectively suppress interference wave, enhance the reflection wave of target horizon, and improve the quality of 3D seismic primary data in loess table area. |
