Abstract
Techniques for Gaussian beam migration imaging are described herein. According to some aspects, a seismic wave field of an earth surface is represented in the form of superposition of Gaussian beams with a present curvature parameter in a time-space domain. A width of the Gaussian beam based function and a spacing between centers of adjacent Gaussian beams of the seismic wave field of the earth surface are set as a preset width and spacing, respectively. A decomposition model is established according to the set seismic wave field. An optimization solution algorithm is applied, based on seismic data and a medium velocity model, to the decomposition model to obtain multiple waveform functions. Gaussian beams corresponding to the multiple waveform functions are propagated, based on the medium velocity model. Migration imaging is performed to obtain migration imaging results.
