摘要
This paper uses the method of petroleum system evaluation,analyzes the evolution and petroleum geologic characteristics of (Ural) foreland basin,interprets the typical oil-gas fields and summarizes the formation conditions and distribution of the fields.It is suggested that in the stage of passive continental margin of Frasnian to Famennian period of Late Devonian,Domanik hydrocarbon source rock with shale and marl was deposited in the foreland basin,which became the most important source rock in this belt.The study shows that the petroleum exploration is in middle stage in this area,but in the offshore of Timan-Pechora Basin and the central,the northern and southern parts of Volga-Ural Basin,their low explorative extents make them have great exploration potentials.
