Abstract: Based on traditional sefroleum geology,this paper deals with same new conceptions about the fact(phenomenon)that oil and gas pools are mostly distributed tonally horizontaly in many basins both at home and abroad.The author deems that in case of low thermal evolution(Ro=0.4-0.70),it is possible for humic organism to generate enough methane to form giant gas fieldss hydrodynamic conditions(fluid potential)and dextrorotation of the earth are important factors that control and affect the formation and distribution of oil and gas reservoirs.In combination with some actual basins in our country this paper also discussed the rneehanism of zonation of the oil and gas distribution.It will provide some new information and an analytical method for more reasonable deployment of the oil and gas prospecting and exploration.
