Embodiment 1
[0063] In order to solve the above-mentioned technical problems existing in the prior art, an embodiment of the present invention provides a method for suppressing noise of a vibroseis.
[0064] figure 1 It is a flow chart of an embodiment of the noise suppression method of the vibroseis in the present invention, such as figure 1 As shown, the noise suppression method of the vibroseis in this embodiment may specifically include the following steps:
[0065] 100. Taking the current suppressed channel as the center, establish a five-dimensional offset vector tile (Offset Vector Tile, OVT) gather corresponding to the current suppressed channel;
[0066] In this embodiment, the five-dimensional OVT gather includes dimensions including offset, azimuth, common depth point (Common DepthPoint, CDP), CDP line and time.
[0067] In a specific implementation process, for the common shot point gather, each seismic trace is placed in the CDP grid (CDP bin) according to the position of th...
