摘要
对随机地震反演技术在WC13 1油田薄钙质夹层随机地质建模中的应用效果进行了分析。随机地震反演的结果 ,可以是波阻抗 ,也可以是速度和密度 ,它们具有更强、更直接的岩石物理意义。随机地震反演技术在南海西部海域是首次应用 ,分辨出了 1~ 2m厚的钙质夹层 ,说明该技术适于薄夹层或波阻抗无法描述油藏的精细描述和地质建模。
The stochastic seismic inversion has been applied to geological modeling for the thin calcareous interbeds in WC13*.1 oilfield, and its effects are analyzed in this paper. The stochastic seismic inversion can result in impedance, velocity or density which are stronger and more direct in petrophysical significance. As the first application in the western South China Sea, this technique has identified calcareous interbeds thick only 1~2 m, suggesting that this technique is suitable for refined reservoir characterization and geological modeling of thin interbeds or other beds that can not be described by acoustic impedance.
