Pre-stack seismic inversion method and device, electronic equipment and storage medium

Abstract

The invention provides a pre-stack seismic inversion method and device, electronic equipment and a storage medium. The method comprises the steps of obtaining multiple pre-stack seismic angle stack data, target layer position interpretation data and logging data; synthetic record calibration is carried out to obtain synthetic record calibration data and seismic wavelets corresponding to each piece of pre-stack seismic angle superposition data, and a seismic wavelet matrix is constructed; based on the seismic wavelet matrix, calculating to obtain a time domain positive operator; based on the frequency spectrum of each seismic wavelet, calculating to obtain a frequency domain positive operator; according to the pre-stack seismic angle superposition data, correlation parameters are obtained through calculation; and constructing a target function, and determining a pre-stack seismic inversion result at least according to the correlation parameters, the time domain forward operator, the frequency domain forward operator, the pre-stack seismic angle superposition data and the target layer position interpretation data. Based on the technical scheme of the invention, the longitudinal resolution and the transverse resolution of the elastic parameter inversion can be improved.
