device and method for directional deconvolution of seismic data

摘要

device and method for directional deconvolution of seismic data. It is a computing device, computer instruction, and method for directional deconvolution of seismic data d with a given source directivity. The method includes obtaining directional operators r, calculating a model u with a modified source directivity based on (1) seismic data d, and (2) an operator consisting of a combination of directional operators r and an inverse transform operator l; using the u model to obtain dfree seismic data with modified source directivity; and generate a final subsurface image using dfree seismic data.
