Quantitative characterization of development of permeable interlayers in continental shale strata

摘要

摘要: 勘探实践表明，富有机质页岩层段中的砂岩夹层或碳酸盐岩夹层的发育程度是页岩油富集高产的关键因素之一。目前尚无针对上述夹层发育程度的定量评价模型和方法，建立页岩相对高渗夹层定量评价模型，完善该地质因素定量评价流程和方法具有重要意义。利用夹层在地层中发育、分布的位置及分散程度，建立表征夹层发育程度的数学模型。以地层岩性属性的地震反演数据体、三维构造建模数据体、钻井数据为基础，以虚拟/实际钻井岩性数据为计算单元，应用夹层厚度比临界值为约束，通过建立数学模型，对钻井开展夹层发育强度（DS）、分布位置（DP）及分散系数（DC）计算。再通过归一化处理综合计算夹层发育指数（STI），结合沉积相研究结果确定的主要物源方向，采用克里金插值计算目的层STI的平面分布。应用上述方法，对渤海湾盆地东营凹陷沙四上亚段STI进行计算，通过与现有钻井试油成果对比，高产井STI主要在0.4~0.8之间，显示STI分布范围对页岩油勘探井的部署具有参考意义。

Abstract: Exploration practice shows that the development of sandstone interlayers or carbonate interlayers in organic-rich shale intervals is one of the key factors for shale oil enrichment and high yield. At present, there is no quantitative evaluation model or method for the development degree of these interlayers. The quantitative evaluation model of relative hypertonic interlayers in shale is established. It is of great significance to improve the quantitative evaluation process. A mathematical model for characterizing the development of the interlayers is established by using the position and dispersion of interlayers in a formation. Based on seismic inversion data, three-dimensional structural modeling and drilling data of the lithology properties of the formation, the virtual/actual drilling lithology data is used as the calculation unit, and the sandstone thin interlayer index (STI) is used as the constraint value. The developmental strength (DS), distribution position (DP) and dispersion coefficient (DC) of the well were calculated. Then, the STI is calculated by normalization, and the main source direction is determined by the results of sedimentary facies research. The STI plane distribution of the target layer is calculated by Kriging interpolation. Using the above method, the STI of the upper part of the Shahejie Formation in the Dongying Sag was calculated. Compared with the existing drilling test results, the STI of the high-yield well is mainly between 0.4 and 0.8, indicating that the STI distribution range has a guiding significance for shale oil exploration.
