摘　　要：叙述了曙一区馆陶组稠油至超稠油的地质特征,查明了油藏的形成机理及油藏分布的控制因素;认为该油藏为自凝结型稠油油藏,原油来自下伏兴隆台油层,原油在运移和成藏过程中,经历水洗作用,使原油粘度增加、凝固点降低,由于原油凝固点温度高于地层温度,原油自凝结形成沥青壳圈闭而聚集成藏,油藏的分布受油源位置、原油密度、粘度和凝固点的控制。The geologic characteristics of viscous and super-viscous oil reservoirs in Guantao Formation of Shuyi Region are denoted. The reservoir forming mechanism and the control factors of reservoir distribution are investigated. It is considered that the reservoir is a self condensate viscous reservoir, where oil is from the underlying Xinglongtai reservoir and it is water flushed during the migration and reservoir forming process. Thus its viscosity increases, condensate point decreases. Because the temperature at its condensate point is higher than that of formation, an asphaltic trap resulted by oil of self condensation is accumulated to be the reservoir, its distribution is controlled by oil position, density, viscosity and its condensate point.
