【摘要】 与叠后地震反演相比,叠前地震反演可得到更丰富的储层信息,可提高储层的描述精度.目前,叠前地震反演主要包括弹性阻抗反演、叠前P波阻抗和S波阻抗联合反演、叠前地震波形反演.文中概述了叠前地震反演各项技术的主要进展及其典型应用实例,提出了叠前地震反演技术在岩性油气藏勘探开发中的应用策略.叠前地震反演技术在未来的油气勘探开发中将有广阔的应用前景.更多还原

【Abstract】 The pre-stack inversion can get more information of the reservoir and improve precise of reservoir characterization than the post-seismic impedance inversion.The pre-stack inversion mainly include the elastic impedance inversion,Pre-stack simultaneous inversion for compressional impedance and shear impedance,and pre-stack waveform inversion.The paper summarizes the key techniques of the pre-stack inversion and its characterization of application,gives the some of t typical cases study,put forward the strategy of the pre-stack inversion in exploration and production for the lithologiccal reservoirs.In the future it will have a wide application in different aspects of reservoir characterization and pre-drill geo-hazard analysis.更多还原
