基于改进阿基米德优化算法的波阻抗反演研究
Research on Wave Impedance Inversion Method Based on the Improved Archimedes Optimization Algorithm
摘要
Abstract
The article proposes an Improved Archimedes Optimization Algorithm(IAOA)aimed at enhancing the accuracy and stability of seismic impedance inversion to address is-sues such as lithological analysis and storage calculations in subsurface media.IAOA im-proves population initialization based on AOA,incorporates automatic balancing of local and global development during iteration,and enhances population information in the later stages of AOA iteration.To evaluate the performance of IAOA for seismic wave impedance inver-sion,three theoretical geological models were designed for algorithm testing.The results were compared among IAOA,AOA,and Particle Swarm Optimization algorithm(PSO)when applied to invert the same model.The PSO algorithm was selected as a comparison be-cause of its wide application and stable performance in seismic wave impedance inversion.The model test results demonstrate that IAOA achieves high precision in inversion results,maintains a stable convergence process,and can effectively contribute to wave impedance in-version tasks.Finally,this paper employs measured a research area in northern China to as-sess the ability of IAOA in inverting actual data.The obtained results indicate that IAOA possesses strong practicality by providing effective subsurface stratigraphic information bene-ficial for subsequent research such as reservoir calculation.关键词
