摘要
Effective sand carrier beds are the sand layers experienced oil and gas migration.The transported hydrocarbon can be identified by the hydrocarbon show and fluid inclusions.Meanwhile,the distribution characteristics of effective carrier beds were studied by the distribution of hydrocarbon source rocks,the spatial location of the sand and tectonic setting.The results show that the distribution of the effective sand carrier beds is characterized by zonation and lamination in Gaoyou sag.The distribution of effective sand carrier beds in Gaoyou sag is multi-controlled by sedimentary facies,structure,distribution range of effective source rock,contact relationship with source rocks,faults connected to source rocks,regional seal,diabase invasion.
