2、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、Es3z2、Es3z3、Es3z5、Es3z6、Es3z7;沙三下亚段页岩油的有利区分布在柳屯
3、洼陷和卫城地区,纵向上分布在Es3x7。关键词:东濮凹陷;有利区优选;泥页岩层系;页岩油层系中图分类号:TEl21文献标识码:A文章编号:1000—3754(2013)06·0155—06oPTIMIZATIoNoFTHEFAVoRABLEAREAoFTHESHALEoILINSHAHEJIEFoRMATIoNoFNoRTHDoNGPUSAGWANGWenguang,LUShuangfang,WANGMin,PENGJun,LUKun,YUANBo。(1.CollegeoftheGeosciences,N
