摘要： 以渤海湾盆地济阳坳陷古近系沙河街组沙三下亚段和沙四上亚段2套页岩为研究对象，从生烃条件及含油性研究入手，进行了页岩油地球化学评价，认为这2套页岩具备形成页岩油的物质基础。建立了有机碳含量、氯仿沥青A含量和溶解烃含量的页岩油分级评价标准，结合自然演化剖面的规律剖析，提出了页岩油富集门限值，东营凹陷沙三下亚段和沙四上亚段、沾化凹陷和车镇凹陷沙三下亚段泥页岩是济阳坳陷良好的页岩油勘探目的层系。

Abstract: Taking the shale members of Lower Es3 and Upper Es4 of the Paleogene in Jiyang depression as research subjects and starting from the hydrocarbon generation condition and oil?bearing property, the geochemical characteristics of the shale oils are evaluated. The results show that the shale members have favorable conditions for forming shale oil. This paper establishes the grading evaluation criteria of shale oil in terms of organic carbon content, chloroform bitumen“A”content and dissolved hydrocarbon content“S1”. Combined with the evolution of profiles, it proposes the shale members’oil enrichment thresholds, and suggests that the shale members of Lower Es3 and Upper Es4 in Dongying sag and Lower Es3in Zhanhua sag and Chezhen sag are favorable target zones for shale oil exploration in Jiyang depression
