Using simulated annealing algorithm to pre-stack seismic inversion

The principle of pre-stack simultaneous inversion and simulated annealing algorithm is discussed.It introduced the technical process to achieve the pre-stack simultaneous inversion using simulated annealing algorithm,and departed the process into four steps: high-fidelity seismic data processing,common angle gather generation,wavelet extraction and synchronous inversion.The application of simulated annealing algorithm in pre-stack simultaneous inversion is described.This method was proved in Sulige Gas field,and the result shows the features: fast calculation,stable algorithm and good prediction effect.Forecasting results verify the effectiveness of this proposed method.
