一种从地震记录中去除面波的方法和装置
摘要：
本申请实施例公开了一种从地震记录中去除面波的方法和装置。该方法包括：对待处理的地震记录进行分频扫描，获得面波频段的分布范围；根据面波频段的分布范围，对地震记录进行小波分频，获取不同频段上的地震记录；根据面波频段的分布范围，从上述不同频段上的地震记录中识别出包含面波的地震记录，对包含面波的地震记录进行径向道变换；根据面波频段的分布范围确定高通滤波的频率，对径向道变换后的地震记录在径向道域进行高通滤波；对高通滤波后的地震记录进行反径向道变换；将反径向道变换后的地震记录和不同频段上的地震记录中不包含面波的地震记录进行小波重构，得到去除面波的地震记录。
摘要（英）：

The embodiment of the invention discloses a method and device for removing surface waves from seismic records. The method includes the steps that frequency division scanning is conducted on the seismic records to be processed, and the distribution range of surface wave frequency bands is acquired; according to the distribution range of the surface wave frequency bands, wavelet frequency division is conducted on the seismic records, and the seismic records on different frequency bands are acquired; according to the distribution range of the surface wave frequency bands, the seismic records containing the surface waves are recognized from the seismic records on the different frequency bands, and radial way conversion is conducted on the seismic records containing the surface waves; according to the distribution range of the surface wave frequency bands, the high-pass filtering frequency is determined, and high-pass filtering is conducted on the seismic records acquired after radial way conversion in a radial way domain; Reverse radial way conversion is conducted on the seismic records acquired after high-pass filtering; wavelet reconstruction is conducted on the seismic records acquired after reverse radial way conversion and the seismic records on the different frequency bands and not containing the surface waves, and the seismic records with the surface waves removed are acquired.
