鄂尔多斯盆地蕴藏着丰富的油页岩资源，积累了大量测井系列齐全的石油钻探资料，但针对油页岩的调查评价工作程度低，可利用的含油率数据十分有限，难以准确评价油页岩资源量。利用陕西铜川地区油页岩探井的测井与含油率分析资料，结合ΔlogR方法，建立了该区油页岩含油率测井解释模型，可较准确地识别油页岩层段和解释计算含油率。在此基础上，利用大量的油气井测井资料解释含油率、识别和统计油页岩厚度，对1.3×104km2工作区内三叠系延长组长7油页岩资源量进行了评价，估算油页岩分布面积为1.08×104km2，预测远景资源量为3866×108t，干馏油页岩油远景资源量为179×108t，具有形成大型-特大型油页岩矿产地的资源潜力，为该区油页岩勘查利用提供了重要依据。

Ordos Basin is rich in oil shale resources and has a series of oil drilling data. However, the investigation and evaluation of oil shale resources are still inadequate due to limited useful oil content data, which makes it difficult to predict oil shale resources prop-erly. According to such drilling data in Tongchuan area as logging and oil content in combination with ΔlogR methodology, the oil content log interpretation model has been established, which can identify oil shale layer and interpret and calculate oil content much more precisely. Moreover, on the basis of oil content and oil shale thickness given by plenty of oil drilling data, the quantity of oil shale resources of Chang 7 of Triassic Yanchang Formation in the study area of 1.3×104km2 is evaluated, and the oil shale distribution area is estimated to be 1.08×104km2. Besides, the quantity of oil shale prospective resources is estimated to be 3866×108t while that of the counterpart of carbonization oil shale is 179 × 108t, which indicates the great potential to form superlarge oil shale resources. The results achieved by the authors provide significant evidence for the exploration of oil shale in this area.
