摘要：NOVELTY - The method involves extracting the time slices of non-uniform three dimensional (3D) seismic data in two spatial directions. The non-uniform quasi-wave inverse transform operator between the uniform warp coefficient and the space loss data under the non-uniform sampling is established and then solved by the linear Bregman algorithm. The homogeneous curve coefficients of irregular seismic data under non uniform sampling are obtained by exact inversion. The three-dimensional seismic data reconstruction method based on linear Bregman algorithm is developed. USE - Method of reconstructing three dimensional seismic data of non uniform curve. ADVANTAGE - The resolution and signal-to-noise ratio of the reconstructed signal is improved. The reconstructing precision of three dimensional seismic data of non uniform curve is improved. DESCRIPTION OF DRAWING(S) - The drawing shows a flowchart illustrating a method for reconstructing three dimensional seismic data of non uniform curve. (Drawing includes non-English language text)
