| 摘 要： | 鄂尔多斯盆地内致密油资源潜力不清，资源分布不明，制约了鄂尔多斯盆地致密油的勘探开发。以鄂尔多斯盆地南部长6、长7和长8段致密油为研究对象，运用小面元容积法和分级资源丰度法2种方法对研究区致密油资源量进行了资源评价，从烃源岩特征、沉积相—储层特征和成藏特征系统分析了鄂尔多斯盆地南部长6、长7和长8段致密油的特征。小面元容积法评价得到长6、长7和长8段致密油资源量分别为12.24×108，8.42×108，9.60×108 t，分级资源丰度类比法评价得到长6、长7和长8段致密油资源量分别为12.13×108，9.00×108，9.50×108 t。高丰度区主要分布在樊学、新安边、吴仓堡、义正、张家湾—高哨和直罗—富县等地区。评价结果为鄂尔多斯盆地致密油的勘探与开发提供指导。

| Abstract: | The exploration and development of dense oil in Ordos Basin is restricted by the unclear potential and unclear distribution of dense oil resources.This study investigates the tight oil of the 6th，7th and 8th members of the Yanchang Formation in the southern Ordos Basin，using the small cell volumetric method and the hierarchical resource abundance analogy method to evaluate the potential of the tight oil resources，the characteristics of the source rocks，sedimentary facies，reservoirs and hydrocarbon accumulation processes have been systematically analyzed for the three members of the Yanchang Formation.Our results show that the geological resources of the 6th，7th，and 8th members of the Yanchang Formation are 12.24×108 t，8.42×108 t，9.60×108 t，respectively，by the small cell volumetric method，and are 12.13×108 t、9.00×108 t、9.50×108 t，respectively，by the hierarchical resource abundance analogy method.The areas with high abundance are Fanxue，Xinanbian，Wucangpu，Yizheng，Zhangjiawan-gaoshao and Zhiluo-Fuxian.These results provide important clues for the future exploration and development of the tight oil resources in the Ordos Basin. |
