摘要
通过对新疆沙南油田沉积特征的分析 ,将其重力流沉积岩分为砂砾岩相、块状砂岩相、粗粒浊积岩相、经典浊积岩相和泥岩相 5大类。利用岩心扫描对 FMI图像进行标定 ,确定了以上 5类岩相的 FMI图像特征 ,然后参照标定的图像对储层进行精细解释 ,从而解决了用 FMI对地质现象解释所存在的多解性 ,为重力流沉积环境下储层规律的研究提供了有力的证据。
According to the analysis of depositional features of Shanan Oilfield in Xinjiang, its sedimentary rock from gravity flow deposition is devided into five lithofacies, i.e. sandy conglomerate, massive sand, coarse grain turbidite, typical turbidite and mudstone facies. FMI image is calibrated by means of core scanning and the features of the five lithofacies mentioned above on FMI image are determined. Then fine interpretation of the reservoir in Shanan Oilfield is made with reference to the calibrated FMI image. Thus multisolution of FMI interpretation is eliminated, providing a solid ground for the study of reservoir under the depositional environment of gravity flow.
