OCCURRENCE AND CORRELATION OF VARIOUS ENERGY RESOURCES IN THE ORDOS BASIN

摘要: 鄂尔多斯盆地蕴藏着丰富的石油、天然气、煤炭、煤层气、砂岩型铀矿等能源矿产,其分布具有南油北气、上油下气、煤层分布广、盆缘有含铀矿化及富集煤层气的特点。物质"来源"研究表明,石油主要源自中生界湖相源岩;天然气除了上古生界煤系源岩外,海相灰岩对成藏也有贡献;煤层气主要由聚煤中心煤化作用形成;铀源可能有中酸性花岗岩的贡献,也含有赋存层位的铀质来源。成矿年代及形成机理表明,它们之间存在着一定的内在成因联系,特别是侏罗系煤层不能形成大型油藏、煤系作为天然气的主力贡献、煤层气区对深盆气的形成补充以及天然气对铀矿化的还原作用等方面表现均较为显著。Abstract: The Ordos Basin is rich in oil,natural gas,coal,coalbed methane and sandstone-type uranium deposits.Oil pools mainly locate in Triassic and Jurassic in the south.Natural gas vertically situates beneath oil pools in the north.Coal measures are widespread.The margin of the basin is characterized by sandstone-type uranium deposits and abundant in coalbed methane.Geneses of various energy resources have been defined by source investigations.Oil is mainly originated from Mesozoic lacustrine source rocks.Natural gas derives from Upper Paleozoic coal series as well as marine limestones.Coalbed gas is formed during the coalification of coal accumulation centers.Uranium source may be offered by medium-acidic granite and uranium-bearing formation.Timing and formation mechanism of these resources suggest that there are genetic relationships among them,especially the difficulty for Jurassic coal to form commercial oil accumulation,the contributions of coal to natural gas,the supplement of coalbed methane to deep basin gas and the reduction of natural gas to uranium deposits.
