中文摘要：

依据泥页岩层系划分标准及横向选区、纵向选层系的原则，在东濮凹陷北部沙河街组优选页岩油有利区。纵向上，基于泥页岩层系划分标准进行泥页岩层系识别，依据资源价值、油气富集概率优选富含页岩油的泥页岩层系（即页岩油层系）；横向上，利用泥页岩层系内有机碳展布、可动资源量及可采性指数的叠合图优选页岩油的有利区。纵、横向结合确定了地下页岩油富集的空间位置：沙三中亚段页岩油的有利区分布在马寨和柳屯洼陷，纵向上分布在Es3zl、Es322、Es323、Es325、Es326、Es327；沙三下亚段页岩油的有利区分布在柳屯洼陷和卫城地区，纵向上分布在Es3x7。

英文摘要：

Abiding by the classifying standards of the mud-shale layer series and selecting principles of horizontal plays and vertical layer series, the favorable areas of shale oil are optimized for the Shahejie Formation of North Dongpu Sag. In vertical, on the basis the above dividing standards, the mud-shale layer series is identified, and furthermore considering the resource value and hydrocarbon enriched probability, the series enriched shale oil i. e. shale oil layer-series is optimized; in horizontal, making full use of TOC spread, movable resources amount and congruent map of the recoverability index, the favorable areas of the shale oil are optimized. The accumulated spaces of the oil is determined by the combination of the vertical and horizontal： the favorable areas in Es3z Mem- ber shale oil are distributed in Mazhai and Liutun Low, in detail vertically distributed in Es3zl, Es3z2, Es3z3, Es3z5, Es3z6, Es3z7 sublayers ; the favorable areas in Es3x Member are located in Liutun Low and Weicheng re- gion, the vertical distribution is focused in Es3x7 sublayer.
