A METHOD FOR REMOVING NOISE FROM SEISMIC DATA |
摘要 |
The present invention is a method for processing seismic data comprising acquiring seismic data using a sweep sequence including a plurality of cascaded sweep segments. The seismic data include a plurality of data segments and a listen time. The listen is combined with an initial data segment. The seismic data segments are phase shifted to a phase of a target data segment to be denoised i.e. removal of ambient, harmonic and coherent noise. A difference between the target data segment and the remaining data segments is determined. If the determined difference exceeds a predetermined threshold, data in the target data segment is replaced with data derived from the remaining data segments. The data segments may be stacked to form a new target data segment. The listen time is extracted from the initial data segment.
