【摘要】 分析了各向同性介质中多分量转换波地震数据采集的有效时窗,在有效时窗内追踪每个反射点的P-P波、P-SV波射线路径,通过求解Zoeppritz方程得出P-SV波与P-P波反射系数的比值,并将该比值的绝对值定义为控制因子G,用G优化最佳时窗的选择,为煤田多分量转换波采集接收时窗的确定提供依据.更多还原

【Abstract】 The effective windows of multi-component converted seismic data’s acquisition in isotropic media were analyzed.Within the effective windows,the P-P and P-SV wave’s ray pathes at all reflection points were traced,and the reflection coefficients’ratios of P-SV to P-P wave were calculated through solving Zoeppritz equations,and the ratios’absolute values were defined as the controlling factor G.Then G values are used to optimize the choice of the best receiving windows,and which provide the foundations for the decision of receiving windows for multi-component converted seismic data’s acquisition in coal-fields.更多还原
