Omnidirectional vector seismic data processing method and apparatus, computer-readable storage medium and device

A computer-readable storage medium including computer-readable instructions, applied to an omnidirectional vector geophone, the omnidirectional vector geophone comprises:

• eight wave detectors and support structures thereof, the support structures are used for supporting the eight wave detectors such that bottom surfaces of each two wave detectors are on one of regular triangular surfaces of a regular tetrahedron, crossing points of working shafts of the two wave detectors that are on the same regular triangular surface that cross with the regular triangular surface are both on an angular bisector of an angle of the regular triangular surface and are symmetric with respect to a center of the regular triangular surface;
• wherein, when being executed, the computer-readable instructions cause a processor to execute at least the following operations:
• 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;
• performing space vector calculation and wave field recovery operation on the pressure wave data and the shear wave data, wherein the wave field recovery operation includes a statics correction and a deconvolution operation;
• performing an imaging operation based on the pressure wave data and the shear wave that are subject to the wave field recovery operation, to obtain pressure wave imaging data and shear wave imaging data;
• performing modeling based on the pressure wave data and the shear wave data that are subject to the wave field recovery operation and the pressure wave imaging data and the shear wave imaging data, to obtain a pressure wave velocity model and a shear wave velocity model.
