【摘要】 地震反演技术是储层建模的重要手段。叠前弹性阻抗反演,它是地震剖面叠加以前利用反演振幅随入射角变化的特征进行波阻抗反演。弹性阻抗反演是利用不同炮检距道集数据及横波、纵波、密度等测井资料,联合反演出与岩性、含油气性相关的多种弹性参数模型,进行储层建模,综合判别储层物性及含油气性。更多还原

【Abstract】 Seismic inversion technique is an important means for reservoir modeling.The prestack elastic wave impedance inversion is to use the character of amplitude various with input angle for inversion before seismic profile stack.The prestack elastic wave impedance inversion technique is to use data of different offsets gathers and s-wave,p-wave and density logging data for joint inversion of lithologic and oil/gas-bearing-related multi-elastic parameters for reservoir modeling to analyze integrative recognition of reservoir nature and oil/gas-bearing ability.更多还原
