摘　　要：AVO技术已经成为油气地震预测中应用最为广泛的技术之一,但常规AVO技术在识别薄互储层、区分流体、解决调谐效应及频散方面存在"瓶颈".频变AVO技术是在频率域研究AVO特征,随着该项技术的迅速发展,频变AVO技术在解决上述问题方面具有优势.本文从频变AVO技术发展的基本状况入手,归纳总结频变AVO技术发展的四个阶段,并对各个阶段具有代表性的技术:频谱交会技术、频散AVO反演技术和基于岩石物理分析的频变AVO技术进行详细介绍.最后指出,基于各向异性研究、基于岩石物理分析的频变AVO研究是该项技术发展的主要趋势.AVO technology has become one of the most widely used technology in oil and gas prediction,but conventional AVO technique in identifying thin interbedded reservoir,distinguishing fluid,solving the tuning effect and dispersion is obviously insufficient.Frequency-dependent AVO technique is studied AVO characteristics in the frequency domain.With the rapid development of technology,frequency-dependent AVO technique has advantages in solving these problems.Beginning with the basis situation of the frequency-dependent AVO technique,we summarize the four stages of technological development frequency-dependent AVO in this paper,and the technical representative at all stages in detail：Spectrum rendezvous technique,dispersion AVO inversion technique and frequency-dependent AVO technique based on rock physics analysis.Finally,the frequency-dependent AVO studies,based on the anisotropic research and rock physics analysis,are the main trends in the development of the technology.
