摘要
苏北盆地白驹凹陷目的层段泰一段储层具有低渗薄互层特征,且薄互层占很大比重,厚层也常具非均质性。由于受测井仪器分辨率所限,常规曲线分辨率较低,造成解释上的困难,极大地影响了对储层的正确评价。为此研究利用反褶积、纵向分辨率匹配和α因子法等薄层测井评价技术来提高常规测井曲线分辨率,论述了白驹凹陷各种常规曲线适用的处理方法。根据与岩心分析、试油结果对比,证明薄层测井评价方法在白驹凹陷的应用效果较好,为该地区的薄层处理解释提供了参考依据。
Thin layer and thin interlayer take great proportion of reservoir of Tai one section, and thick layer is always lack of homogeneity in Baiju Sag, Subei Basin. Due to the limited resolution of logging tools, which caused the resolution of conventional curve low and the interpretation difficult, the accuracy of evaluated reservoir was greatly influenced. To improve conventional curve resolution, some logging evaluation techniques for thin layer were used, such as deonvolution, vertical resolution matching and α factor method. The applicative processing method for all kinds of conventional curves in Baiju Sag is illustrated. According to the core analysis and test result comparison, the application effect of logging evaluation technique for thin layer in Baiju Sag proved to be effective. This paper is helpful for thin layer processing and interpretation in this area.
