摘　　要：东营凹陷沙河街组岩性油藏的形成与分布在宏观上受多种元素的控制,这些宏观地质控制因素包括构造带类型、沉积体系域类型、储集相类型、烃源岩条件和盆地温压条件等.根据岩性油藏的自身特点分析认为,东营凹陷沙河街组岩性圈闭能否成藏主要受到4大主控元素的控制,分别为岩性油藏输导通道因素、流体动力因素、储层临界物性因素、砂体封闭性因素.经研究在牛庄洼陷发现沙河街组岩性油藏具有“三元主控”的特征.Shehejie Formation of Dongying Sag develops many lithologic reservoirs.The formation and distribution of these lithologic reservoirs are controlled by many graphic factors,including the types of structural belts,the types of dispositional system tracts,the types of reservoir facies,the conditions of source rock and the condition of the temperature-pressure,etc.Through the comprehensive analysis of the characteristics of the lithologic reservoirs in Shehejie Formation of Dongying Sag,it is held that whether the lithologic traps can form oil reservoirs is usually controlled by four major factors:hydrocarbon migration pathways,power condition of fluid flow,physical properties of reservoirs,and the sealing condition of sandbodies.But the formation of the lithologic reservoirs in Niuzhuang Subsag is controlled by three factors.
