| 摘 要： | 苏里格地区储层段砂岩与泥岩的纵波速度、密度和纵波阻抗等参数相互叠置，造成常规叠后波阻抗反演难以进行储层预测和流体识别，为此，利用测井资料，开展了以地震岩石物理参数分析为基础的叠前储层预测与流体识别可行性研究。结果表明，利用岩石的弹性物理参数能很好地区分砂岩和泥岩；利用储层含气性敏感参数，可进行流体识别。储层舍气性敏感参数研究为此工区开展叠前储层预测和流体识别提供了依据。

| Abstract: | Because the compressional wave velocity, density and longitudinal wave impedance parameter of reservoir sandstone and mudstone in Sulige Region overlay eaeh other, the post-stack acoustic; impedance inversion is difficult to reservoir prediction and fluid identification. Therefore, using the logging data, this paper studies the pre-stack reservoir prediction and fluid identification based on the parametric analysis of seisnfic rock physics. The results show that the elastic physical parameters can distinguish between sandstone and mudstone, and identify the fluid based on the reservoir or gas sensitive parameters. This study can provide basis for the study of pre-stack reservoir predietion and fluid identification. |
