The invention relates to a frequency wavenumber domain high-angle fracture extraction method and device, a storage medium and equipment, and the extraction method comprises the following steps: a, measuring a seismic crack to obtain an original seismic data volume, and splitting the original seismic data volume into a plurality of adjacent sub-blocks; b, performing f-k transformation and f-k inverse transformation processing on each sub-block body in the step a; and c, splicing the plurality of sub-blocks processed in the step b to obtain a high-angle fracture extraction result. The extraction method belongs to a high-angle continuous fracture reflection surface extraction method, and solves the problem that a traditional fracture information extraction method for seismic data volumes such as a coherent body and a curvature body cannot extract a high-angle fracture reflection surface.
