摘　　要：针对大安寨油藏致密的特点,结合钻井、测井资料建立地震正演模型,对模型正演计算的合成记录进行随机地震反演研究,结果表明该反演方法适用于大安寨致密介壳灰岩储层的预测。进而对实际三维地震资料进行反演,其预测结果与实钻资料分析相吻合。Daanahai reservoir is a tight-oil one.So,in this study,a seismic forward model is established combining with drilling and well-logging data.And a stochastic seismic inversion is conducted to the synthetic record calculated from this model.Results show that the inversion is suitable for predicting the shell limestone of Daanzhai tight- oil reservoir.Moreover,the inversion to the actual 3D seismic data is implemented,and its prediction result accords with the analysis of actual drilling data.
