虽然储层地震反演技术在储层预测与描述中取得了一些效果,然而由于复杂的地震地质条件以及对该项技术的应用条件缺乏深入系统的研究,在一定程度上影响了该项技术的广泛应用。在对目前反演方法分类描述的基础上,通过理论模型以及大量资料的反演处理实践,研究总结了几种反演方法各自的适用条件,阐述了反演技术在应用中存在的一些关键问题,提出了相应的解决对策。

Although some progresses have been made in reservoir prediction and description by application of seismic reservoir inversion technology, complex seismic and geological conditions and inadequate research on its application conditions impedes the wider use of this technology. Eased on a classification of available inversion methods, the author summarized the application conditions for each method through theoretical modeling and data processing practice on a large quantity of real data. The key problems in the application of inversion technologies and policies in dealing with these problems are put forward.
