横波观测在地震勘探中,特别在增加岩性参数如 V_P/V_S 的确定方面正受到更大的关注。本文论述在常规地震工作中使用水平检波器进行的转换波观测工作。野外技术和数据处理使得转换波的采集和解释能与常规地震测量联结起来。对转换波记录的专门解释使我们得到横波速度和V_P/V_S 的关系。
S-wave observations are receiving more attention in seismic exploration, especially in determining lithologic parameters such as V_P / V_S. This article discusses the use of horizontal geophones in conventional seismic surveys. Field technology and data processing allow the acquisition and interpretation of converted waves to be linked to conventional seismic surveys. Dedicated interpretation of converted wave records leads us to the relationship between shear wave velocity and V_P / V_S.
