The second and third row structure exist the middle-turn low and mature Jurassicoil-gas from Cretaceous-Jurassic floors.
第二、三排构造存在白垩系—下第三系中转侏罗系低成熟—成熟油气的特征。

Vertically, coal distributes in Permo-Carboniferous and Jurassic; oil and uranium distributes mainly in Jurassic while gas distributes in Ordovician and Permian.
在纵向上，煤聚积于石炭—二叠系和侏罗系，石油和铀矿主要分布在侏罗系，天然气则储集在奥陶系和二叠系。

So it is important to rebuildpalaeogeomorphology and geology reservoir model and study oil-gas accumulationregulation accurately for oil-gas exploration of Jurassic in Ordos Basin.
