摘要： The invention concerns a method for producing a composite block from seismic recording blocks, characterised in that it consists in: producing independent primary seismic blocks, each seismic block being constructed from seismic data registered along a predetermined acquisition direction, so as to obtain n primary seismic blocks {Ai(x, y, z)} with i varying from 1 to n, n being greater or equal to 2; computing for each point of each primary block Ai a quality criterion value representing the seismic attribute local quality, so as to obtain n quality criterion blocks {Qi(x, y, z)} with i varying from 1 to n, each quality criterion block Qi being associated with the primary block Ai; constructing a composite seismic block C(x, y, z) whereof each sample is computed as a combination of sample values of blocks Ai(x, y, z) weighted by their relative qualities Qi(x, y, z).
