Our method is based on non-linear convolution model and uses artificial nervous net algorithm and simulated annealing algorithm, introducing the acoustic impedance as condition of constrained solution to avoid the hypothesis of wavelet or reflection coefficient in common seismic inversion, and adopting the control of fine seismic interpretation model in extrapolation 反演方法以非線性褶積模型為基礎(chǔ),引入井旁聲阻抗作為解的適定性的約束條件,避開一般地震反演對(duì)地震子波及反射系數(shù)的假設(shè)。反演外推采用精細(xì)地震解釋模型控制。算法上,引用人工神經(jīng)網(wǎng)絡(luò)和模擬退火算法。
