Method for attenuating noise in seismic data |
摘要 |
The invention is a method for attenuating noise in seismic data traces, in which at least a portion of the noise is noncoherent in the common-shot domain but coherent in the common-receiver domain, the coherent noise having a move-out velocity different from the move-out velocity of the data signal in the seismic data traces. The method comprises sorting the seismic data traces into common-receiver order and using the difference in move-out velocities to separate the coherent noise from the data seismic signal. This method is useful in suppressing noise in two and four-component ocean bottom cable data.
