【摘要】 探讨了极化滤波法在海底多分量地震数据中纵横波波场分离的应用。通过振幅随偏移距变化的P波和PS波地震记录的合成原理构建地质模型数据,利用地质模型数据和实际海底多分量数据对该法进行应用,并绘制矢量端点图说明分离效果。结果显示,以上数据中垂直Z分量的转换波和径向R分量的纵波基本消失。对于海底多分量数据,极化滤波法能够将纵横波波场彻底分离。更多还原

【Abstract】 The paper discussed the application of polarization filter in the wave-fields decomposition of the ocean bottom multi-component seismic data.It constructed the P wave and PS wave seismic data of a geological model.Polarization filter is applied to the geological model and a real ocean bottom multi-component seismic data.The vector plots before and after decomposition are presented for analyzing the results.PS wave of vertical Z component and P wave of radial(horizontal) R component disappear in the processing results.Polarization filter can effectively do the processing of wave-fields decomposition of the ocean bottom multi-component seismic data.更多还原
