Abstract: In the paper,regional geological basis forming stratigraphic-lithologic pools are expounded firstly,that is,(1) there are two types of fault basins,(2) three types of sedimentary systems and five types of reservoir,(3) three types of stratigraphic overlap-uncomformity associated with source beds.Conditions forming stratigraphic-lithologic pools and characteritics of stratigraphic-lithologic pools are discussed as an important problem.The authors present a distribution model of accumulation belts of stratigraphic-lithologic pools in fault basins.has certain significance to the exploration of stratigraphic-lithologic pools.
