【摘要】 二分量（Ｘ，Ｚ） 理论合成地震记录的处理证明了极化滤波的思想是正确的，也是目前分离二分量记录中Ｐ波和ＰＳＶ波的一个比较有效的方法。各种滤波参数对二分量地震记录滤波效果影响规律的试验、分析结果表明：（１）在滤波器的滤波参数中对滤波效果影响最大的是极化方向的加权值ｑ，其次是滤波的时窗值Ｎ，极化程度加权值ｐ 对滤波效果影响不大；（２）对不同分量、不同炮检距、不同深度的地震记录应采用不同的滤波参数（ｑ，ｐ，Ｎ）进行滤波处理，只有正确地选取滤波器的滤波参数，才能获得比较满意的滤波结果更多还原

【Abstract】 The thought of polarization filtering is proved to be correct with theoretical two component(X,Z)seismic recording processing.The results of Various filtering parameters affecting two component seismic record filtering show:(1)polarization direction’s weight value(q)is the largest affecting factor,polarization filtering time windows(N)is secondary and polarization degree’s weight value(p)has little effect on filtering parameters of the filter,(2)seismic records of different components,different distances between shot and collect and different depths must be processed by different filtering parameters.As long as correct filtering parameters of filter are selected,satisfied filtering results can be acquired.更多还原
