Embodiment Construction
[0021] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0022] The process flow of the seismic prestack signal clustering method in the embodiment of the present invention is as follows figure 1 As shown, it specifically includes the following steps:
[0023] Step S1. The structure-oriented filtering algorithm removes noise, preserves structural features, and organizes the data of the target horizon segment into a format required by subsequent algorithms. Here, the structure-oriented filtering algorithm is usually used to remove noise, which can minimize the impact of noise on subsequent processing;
[0024] Each position of the prestack signal has multiple azimuths, that is, if a single azimuth data dimension is d, for seismic data with s azimuths in total, the characteristic data dimension of each position is s·d. Before performing the clustering algorithm, it is necessary to use the structure-guided filt...
