%X The palaeo-structrual pattern of Ordovieian are three uplifts and two neks and one depress in Ordos basin. Three uplifts control together sedimentary system of Ordovician, at the same time control the development of the original reservoir. After sedimentary of Ordovician, sedimentary are interrupted about a hundred million years , karst reservoir developed widely. From benxi formation to middle Trias, the upand-down configurations of Ordovician weathered crust peak are very steady, namely high in the middle and bellow in the east. There are a abrupt slope between uplift and depress, it is important to evolution of karst reservoir. Irate trias, the up and-down configurations of Ordovician weathered crust peak are high on the west-north and low on the east south, oil gas moved to west-north. The middle Jurassic, the up-anddown configurations of Ordovician weathered crust peak are high on the east and low on the west, oil-gas adjusted again, moved to east.
