摘要: 浅层工程地震勘探单炮记录中包含了丰富的反射波和瑞雷面波信息,在实践应用中,采用固定接收排列的多次叠加观测系统,获得完整的波场信息,在后续处理中,可分别按照瑞雷面波和反射波的波场特征处理,实现一次数据采集,多参数综合解释。通过广西某工程的浅层地震勘探实例,介绍了采用全数字检波器及本观测系统采集的数据,提取瑞雷面波获得瑞雷面波速度结构,用于近地表速度结构重建,并通过拟合用于反射剩余静校正计算,提高反射叠加剖面的质量,并获得了较好的效果。

Abstract: In the shallow seismic geophysical investigation, the records of a single blasting contain information for the reflection and Raleigh waves. The fixed arrays of the receiving sensors are arranged in the field and the complete wave information can be collected. The surface Raleigh wave information can be obtained throughout the post process and the residual reflection calibration calculation can be performed using the data fitting method. Therefore, through one time data acquisition, both the surface Raleigh wave and the reflection wave information can be characterized and interpreted.
