【Abstract】 As a new thinking and method of research during hydrocarbon exploration, the petroliferous system has got attention from more and more scholars recently. In this paper, the Ordos Basin is preliminary divided into the Middle, the Upper and the Lower Paleozoic three gas bearing systems according to the source of hydrocarbon, the stratohorizon of hydrocarbon occurrence and the assemblage of reservoir and cover. At the same time, the characteristics of the Lower Paleozoic gas bearing system are described emphatically, the distributive rule of the Lower Paleozoic natural gas is summarized, and the favorable prospecting zones potential are pointed out.更多还原
