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。
Based on the analysis of the sedimentary characteristics of the Shanan oil field in Xinjiang, the gravity flow sedimentary rocks are divided into five categories: glutenite block, massive sandstone facies, coarse turbidite facies, classic turbidite facies and mudstone facies. The FMI images were calibrated by core scanning to determine the FMI image features of the above five types of lithofacies, and then finely interpreting the reservoir with reference to the calibrated images to solve the multi-solution of the interpretation of geological phenomena by FMI, which is Gravity flow deposition environment under the law of the reservoir provides strong evidence.
