鄂尔多斯盆地多种能源矿产分布特征与协同勘探

Distribution and Co-Exploration of Multiple Energy Minerals in Ordos Basin

鄂尔多斯盆地富含油、气、煤、铀等多种能源矿产。多种能源矿产在空间上具有一定的分布规律和组合形式,在时序上具有较为一致的矿产富集和后期保存、改造时期,在成因上具有一定的成生关系。结合多能源矿产的成矿背景、成藏(矿)机理、赋存规律、勘探理论与实践等,基于经济效益最大化和勘探方法最优化原则,建立了鄂尔多斯盆地多种能源矿产的协同勘探模式,将盆地划分为7个协同勘探区,每一个勘探区以某一种或两种矿产为主探,兼探其他矿产。在协同勘探模式的基础上,针对不同协同勘探区,制定了相应的协同勘探方法,为多种能源矿产协同勘探的实施奠定了理论基础。

Ordos basin is abundant in energy minerals of oil,gas,coal and uranium.Multiple energy minerals have some distribution laws and assemblage styles,the accordant temporal stages for accumulation,conservation,and reformation of mineral reserves.Therefore,these minerals probably have some relation in genesis.Based on mineralization settings and mechanisms,accumulation laws,and exploration theory and practice,as well as rules of the largest benefit and the optimized prospect methods,the co-exploration modes have been established.The Ordos basin is divided into seven co-exploration zones.In each zone,one or two types of minerals are designated as the main exploration objective and other minerals as secondary aim.On the basis of co-exploration modes,different co-exploration methods are worked out for different co-exploration zones,and this will lay theoretical foundation for exploration of multiple energy minerals.
