Abstract
Combined with marker bed,jurassic stratigraphic in Ordos basin was divided into An’ding formation,Zhiluo formation,Yan’an formation and Fuxian formation by the method of logging facies and lithofacies,then the Yan'an formation was divided and compared,which has important significance to steady increase oil and gas production in future and to find oil and gas target.
