摘　　要：随着世界范围内油气资源的紧张,油页岩成为一种重要的能源来源。我国油页岩资源十分丰富,在国内多个盆地均有发现。新疆巴里坤县大长沟盆地东部在前期勘探中已发现有油页岩资源,但尚未进行详细勘探。通过钻井及测井资料,明确了研究区油页岩的测井曲线特征,构建了测井重叠图与交会图识别油页岩的方法。通过矿石含油率、工业分析、铝甑分析、元素分析等岩心实验,确定了研究区油页岩矿石品质,结果表明:研究区油页岩含油率为中等品质,灰分较低,含硫量低,油收率高,具有较高的工业开采价值。通过构建开发潜力指数,对研究区重点油页岩层进行了开发潜力评价,明确了研究区中部与西部为开发潜力较高的区域。With the tightening of oil and gas resources worldwide,oil shale has become an essential source of energy.China is rich in oil shale resources,which have been found in many domestic basins.The eastern part of Dachanggou Basin in Balikun country,Xinjiang,has been found to have oil shale resources in the preliminary exploration but has not been explored in detail.The logging curve characteristics of oil shale in the study area were clarified,and the method of identifying oil shale by logging overlap and intersection diagrams was constructed.The ore quality of oil shale in the study area was determined through the core experiments of ore oil content,industrial quality,aluminum retort analysis,and elemental analysis,and the results showed that the oil content of oil shale in the study area is of medium quality,with low ash content,low sulfur content,and high oil yield,which has a high industrial exploitation value.By constructing the development potential index,the development potential of the most valuable oil shale layers in the study area was evaluated,and the central and western parts of the study area were identified as areas with higher development potential.
