摘　　要：通过回顾济阳坳陷古近系—新近系页岩油的勘探历程,总结了前期页岩油勘探取得的理论成果和形成的技术系列,剖析了页岩油富集要素,结合页岩油已钻井实际情况,指出了下一步页岩油部署的方向。勘探实践表明,济阳坳陷陆相页岩不同于北美地区已突破的海相页岩,具有非均质性强、成岩作用弱、成熟度低等特点,需理论创新、勘探思路转变,形成适合东部陆相页岩油勘探的相关理论和配套技术方法;陆相页岩油赋存样式的复杂性,需要分类型、分步骤实施勘探,应先突破夹层、微裂缝、优质岩相发育的混合型页岩油,在其有效经济动用的基础上,再部署实施基质型页岩油钻探,尽快完善适用于东部陆相页岩油的目标优选评价体系,开辟老油区增储上产新领域。By reviewing the exploration process of the Paleogene-Neogene shale oil in Jiyang Depression,the theoretical achievements and the technology series obtained from the previous shale oil exploration were summarized and the elements of shale oil enrichment of the Tertiary in Jiyang Depression were analyzed.Besides,the direction of shale oil deployment was pointed out considering the actual situation of drilled shale oil wells.Exploration practice shows that the continental shale oil in Jiyang Depression is different from the marine shale oil that has been drilled successfully in North America,which is characterized by strong heterogeneity,weak diagenesis and low maturity.Theoretical innovation and new exploration ideas are necessary to establish relevant supporting technologies and methods suitable for eastern continental shale oil exploration as soon as possible.The complexity of the occurrence pattern of continental shale oil requires a classified stepby-step exploration.The mixed shale oil in the interlayer,micro-crack and high-quality lithofacies should be first developed.On the basis of its effective economic production,the implementation of the matrix shale oil drilling and deployment will be carried out next,and the target optimization evaluation system suitable for eastern continental shale oil should be improved as soon as possible,in order to open up new exploration targets to increase the reserve of old oilfields.
