  • Patent number: 10578757
    Abstract: The invention discloses an omnidirectional vector seismic data processing method and apparatus, a computer readable storage medium and a device, applied to an omnidirectional vector geophone. Wherein the method comprises: collecting omnidirectional vector seismic data of the omnidirectional vector geophone, and performing a pre-processing operation on the omnidirectional vector seismic data; performing pressure and shear waves separation operation on the omnidirectional vector seismic data after the data is subject to the pre-processing operation, to obtain pressure wave data and shear wave data; sequentially performing space vector calculation, a wave field recovery operation and an imaging operation on the pressure wave data and the shear wave data, and then performing modeling to obtain a pressure wave velocity model and a shear wave velocity model.
