Method and device for attenuating random noise in seismic data

摘要

Methods (600, 1100) and devices (1200) for seismic data processing attenuate noise by replacing an attribute value v(i) of a selected data point (700) i with a weighted average v̂(i) of attribute values of data points j from a window (710) that includes the selected data point i. The contribution to the weighted average of an attribute value v(j) corresponding to a data point j depends on how similar attribute values in the neighborhood N_j of the data point j are to attribute values in the neighborhood N_i of the selected data point i.
