摘要
应用层次分析法 ,将双河油田核桃园组第三段的地层边界到交错层的纹层边界的泥岩隔层分为 10个层次。利用测井曲线星形图将 5级以上层次的隔层区分开来 ,依靠测井曲线和岩心识别隔层厚度和层次 ,进而实现对隔层层次的描述。在隔层成因沉积学解释的基础上 ,运用密井网解剖提取隔层的宽度、厚度、宽厚比和对称性等形态参数 ,建立了隔层分布的知识库 。
Mudstone barriers from the formation boundary of the third section of Hetaoyuan Formation to the surface of laminas within the cross-bedding in Shuanghe Oilfield were classified into ten degrees of hierarchies. The barriers over five degrees were determined by logging star-plot. The thickness and frequencies of the barriers were described by the use of cores and logging curves. On the interpretation principles of genetic sedimentology, a knowledge bank for storing barrier distribution parameters including thickness, width, width-to-thickness ratio and the symmetry of barriers was built by means of close-well correlation, which provided the basic conditions for hierarchical reservoir modeling.
