地震全波形反演方法研究综述

The review of seismic Full waveform inversion method

近年来,随着计算机硬件水平的提高,地震全波形反演技术研究快速发展,并有效的推进了油气勘探.本综述主要对当前地震全波形反演主要存在反演非唯一性、噪声敏感性、初始模型强依赖、易陷入局部极值、计算量大等问题进行调研,重点介绍了地震全波形反演方法在时间域,频率域和Laplace域内的各种改进和优化的策略,为全波形反演方法研究提供参考.

There are some problems in the researching of waveform inversion at present, such as the non-uniqueness problem, its sensitivity to noise, depend only strongly on the initial model, convergence easily to the local minimum and general computational limitations and so on. According to the inversion content of the 78th SECT Annual Meeting, we introduced the improvement and optimization of seismic waveform inversion method in the time domain, frequency domain and Laplace domain, which has a significant effect on further research waveform inversion method.
