摘要: 本文通过系统的有机地化研究后认为:下中新统三号沟组暗色泥质岩系是盆地重要的烃源层,中-上中新统回环组暗色泥质岩系是潜在的烃源层。中新世良好的古气候条件和还原的沉积水介质环境有利于中新统生油岩系的发育。Abstract: Based on systematic organic geochemical research,it is considered that the dark argillite series in the Lower Miocene Sanhaogou Formation is the important hydrocarbon source layer of the basin,the dark argillite series in the Middle-Upper Miocene Huihuan Formation is the potential hydrocarbon source layer.The good paleoclimate conditions and the reducing water medium environment for sedimentation in the Miocene are favorable for the development of the Miocene hydrocarbon source rock series.
