On the base of core observation, starting with individual-well facies, combining with the models of seismic and logging facies, along with numerous analysis data of lithology and grain size, etc. the direction of clastics source, depositional system, structure-petrographical zone and its oil-bearing factor are researched. The conclude shows it has two large source areas, which are eastern and western source areas respectively. Five large drainage systems controlled the distribution of eleven sand bodies. Finally, five types of depositional system, such as fan-delta, are classified. Six kinds of structure-petrographical zone, such as the type of abrupt slope fan-delta structure-petrographical zone with platform, are summed up. Meanwhile, the oil-bearing factor of three types of structure-petrographical zone, different from the typical single rifted sag, is discussed preliminary.
