摘　　要：该文在对汶东凹陷主要构造特征进行剖析的前提下,结合大量现场地质资料,对该区储集层进行了认真细致的研究,提出了古近系大汶口组地层既是主力生油层,又是主要储集层的认识。认为该区主要储油岩是碳酸盐岩、油页岩和砂岩;主要储集空间是原生孔隙、裂缝和次生溶孔;断裂构造控制着凹陷的形态和沉积,控制着裂缝发育带,控制着油气藏分布。为该区的进一步勘探与开发提供了依据。On the premise of analyzing main structural features of Wendong sag, combining a large amount of on-site geologic data, the paper made a serious and detail stud y on the reservoirs of the area, putting forward the viewpoint that Dawenkou gro up formation of palaeo-recent series is both major oil source formation and main reservoir. The author thought the dominant reservoir lithology was carbonate ro ck, oil shale and sandstone, main storage space was original pore, fracture and secondary solutional void, ruptural structure controlled sag morphology and depo sition, fracture developed belts and reservoir distribution. The paper provided the basis for further exploration and development in this area.
