【摘要】 风成沙漠区表层吸收衰减十分严重,造成地震波下传能量很弱,并且各种干扰极为发育,使得所获地震资料品质低。首先分析了风成沙漠区的表层地质条件以及干扰波特征,然后在应用模型正演和精细表层结构调查的基础上,进行了激发方式、激发井深等试验,找到了较好的激发介质,确定了通过组合激发提高风成沙漠区资料品质的地震激发方式。更多还原

【Abstract】 Because of the strong attenuation from the near surface in aeolian sand area,seismic data are weak.The quality of seismic data is further deteriorated by diverse noises.Based on an investigation of the near surface structure and interferences in the aeolian sand area,we carried out forward modeling and experimenting on shooting methods and parameters such as shot depth and charge size.Optimal lithology and shot array for exciting seismic waves were determined,which guarantees the quality of seismic data in aeolian sand area.更多还原
