Hu Tian-yue, Wang Run-qiu, Wen Shu-liang. Multibeam Filtering Method to Eliminate Multiple Seabed Seismic Data from the Sea. Petroleum Geophysical Prospecting, 2 0 0 2, 37 (1): 18 ~ 23 In this paper, The basic principles of multiples and the processing results of synthetic data are described in detail. The implementation steps and effects of using the poly-beam filtering method to eliminate multiple waves in the seismic data of two sets of deep-sea areas in the South China Sea are described in detail. For a large range of intense multiple waves produced by coral reefs, the multi-use clustering filtering method is used to eliminate multiple ranges of multiple waves respectively, and the optimization effect of higher resolution and smaller calculation amount is achieved. The processing results show that the beamforming method can eliminate the relatively strong multiple and enhance the weak primary. The results of processing a deep seabed seismic data of a seabed multiple-ocular submarine in the southeastern part of the Outer Mongolia Basin show that the clustering filtering method is quite effective in eliminating long-range and near-channel multiple waves and is superior to the conventional two-dimensional filtering method in multiple times Wave suppression effect
