摘　　要：为揭示鄂尔多斯盆地多种能源矿产间的关系,根据盆地石油、油气伴生水以及煤、煤层夹矸、铀矿及围岩样品的氯仿沥青中57种元素的分析结果,进行了Q型聚类分析。结果表明:侏罗系下统延安组石油、侏罗系中统直罗组石油与三叠系延长组石油有相近的成因特征;三叠系延长组石油沥青、三叠系延长组含油砂岩沥青与侏罗系中统直罗组石油沥青具有类似的成因特征;神木侏罗系下统延安组煤沥青、东胜侏罗系中统直罗组煤沥青、铜川陈家山侏罗系下统延安组煤层石油以及铜川陈家山侏罗系下统延安组煤沥青成因特征相近;铜川陈家山侏罗系下统延安组煤层石油沥青可能与准格尔黑岱沟石炭二叠系煤沥青具有成因上的联系;侏罗系下统延安组石油沥青与放射性铀矿的形成具有密切关系;天然气的物质来源复杂,且与石油和煤的进一步演化有一定关系。鄂尔多斯盆地多种能源矿产成因较复杂、相互间关系密切,且具有多源性成藏(矿)特征。In order to reveal the relationship among multiple energy mineral deposits in Ordos Basin, the contents of 57 elements of the oil, oilfield water and the chloroform bitumen of coal, gangue, uranium deposit and their wall rock was calculated by Q-clustering. The results showed that genetic features of the oil with Lower Jurassic Yan＇an Formation and Middle Jurassic Zhiluo Formation and the petroleum asphalt with Triassic Yanehang Formation was similar; the petroleum asphalt of Triassic Yanchang Formation, the asphalt in oil sandstones of Triassic Yanchang Formation and the petroleum asphalt of Middle Jurassic Zhiluo Formation had similar genetic features; the coal asphalt of I.ower Jurassic Yan＇an Formation in Shenmu and Middle Iurassic Zhiluo Formation in Dongsheng, the petroleum and coal asphalt in the coal bed of 1.ower Jurassic Yan＇an Formation in Chenjiashan of Tongchuan had similar genetic features; the petroleum asphalt in the coal bed of Lower Jurassic Yan＇an Formation in Chenjiashan of Tongchuan was in connection with the coal asphalt of Permo Carboniferous in Heidaigou of Jungar; the petroleum asphalt of Lower Jurassic Yan＇an Formation was closely related with the enrichment of uranium mineralization; the origin of natural gas was complicated, and related with the further evolvement of petroleum and coal. The origin of multiple energy mineral deposit was complicated, correlative and the mineralization/reservoiring was muhi-source in Ordos Basin.
