与P—SV转换波和横波有关的几个速度参数

Velocity Parameters on P-SV Conversion Wave and Shear Wave

针对P—SV转换波资料的特点,基于水平层状介质模型,从"深度唯一"的法则出发,定义和推导了P—SV转换波资料解释中使用的若干速度参数,介绍了一种根据质量好的纵波与P—SV转换波资料求取横波速度信息的方法并验证了其实际计算效果。

Based on specialty of P-SV conversion wave and model with horizontal layered medium, we defined and deduced some formulas about velocity parameters from principle of ＂The depth is the only one＂. These velocity parameters can be used to interpret of P-SV data. Introduced a method using P wave and P-SV wave data with good quality to obtain velocity information of shear wave and showed actual calculating effect.
