Full-waveform inversion method and device, storage medium and electronic equipment

The invention relates to the technical field of velocity modeling and seismic imaging of oil and gas exploration and development, in particular to a full-waveform inversion method and device, a storage medium and electronic equipment, and solves the problems of low resolution and insufficient precision when a full-waveform inversion method is used for processing a complex stratum. The method comprises the following steps: acquiring actual seismic data and an initial velocity model; acquiring simulated seismic data according to the initial velocity model, introducing a high-order total variation regularization item according to the actual seismic data and the simulated seismic data, and constructing a high-order total variation regularization target functional; processing the high-order total variation regularization target functional through seismic wave forward modeling to obtain an inversion solving target functional; solving the inversion solving target functional to obtain a full-waveform inversion iterat
