摘　　要：赵凹油田安棚主体区厚油层隔夹层分布复杂,非均质性严重。通过利用岩心和测井资料,识别出泥质隔夹层、钙质隔夹层和物性隔夹层3种类型隔夹层,分析了不同类型隔夹层成因与岩性特征;在岩心标定测井的基础上,选取合适的测井曲线建立了不同类型隔夹层测井响应判识的定量标准。基于储层构型研究以及层次分析方法,将隔夹层分为单层间隔层、单砂体间夹层和单砂体内夹层3个层次,并分析了不同层次隔夹层的分布规律。The distribution of the interlayers is of within thick oil reservoir in anpeng Mainbody Area of Zhaowa Oilfield, the heterogeneity of which is serious. By using core and well logs data, three types of barrier interlayers are identified in our discussion, including mudstone barrier interlayers, carbonate barrier interlayers and physical barrier interlayers. Their formation will cause and lithologic characteristics. On the basic of core calibration logging, the quantitative criteria in logging response identification for different interlayers are established in selecting appropriate logging curves. Based on the research on reservoir configuration and analytic hierarchy process, the target reservoirs are divided, into three hierarchies, including the barriers between the two intercalations between the two single sand bodies and the intercalations in a single sand distributions is analyzed.
