摘　　要：大民屯凹陷勘探实践证实沙四段存在着丰富的页岩油资源,从泥页岩的有机非均质性入手,借助实验测试及改进模型测井方法,开展泥页岩的有机非均质性评价,从而识别出页岩中有机质富集段。结果表明:有机质富集段的泥页岩TOC高,生烃潜力大,含油性较好,是页岩油发育和聚集的有利层段,也是非常规资源勘探的现实目标。该项研究结果为深入认识页岩油的分布规律和下一步的勘探部署提供依据。Exploration practices in Damintun Sag have proved that there are plentiful shale oil resources in Sha4 member. Accordingly,the experiment test and improved model for logging were adopted to evaluate the organic heterogeneity of muddy shale,so as to identify organic matter enriching intervals in shale. The result shows that such intervals have high TOC,big hydrocarbon generation potential,and better oil-bearing potential. So they are favorable intervals for shale oil development and accumulation,and also practical target for exploring unconventional hydrocarbon resources. This research result can provide basis for deeper cognition on shale oil distribution regularity and future exploration deployment.
