Seismic data inversion method, device and apparatus

The invention relates to a seismic data inversion method, device and apparatus. According to the method of the invention, an l2 norm constraint-based elastic impedance inversion optimization model isbuilt; an optimal regular parameter is determined by means of a threshold filtering factor and an L-curve criterion, and then, the Tikhonov filtering factor is adopted to solve the minimum solution ofthe optimization model, and therefore, calculation accuracy and the stability of the solution can be effectively improved; the algorithm is tested by a low signal noise ratio theoretical model and actual seismic data; the inversion result of the low signal noise ratio theoretical model is basically consistent with a model forward modeling condition; an actual seismic data-based elastic impedanceinversion result is consistent with a rock physics analysis result in a region; and therefore, the prediction result of further obtained brittleness index distribution is also matched with a borehole.The algorithm has the advan
