The eastern part of North China is an important energy-resource region in oft-com:office:smarttags" />China, and also a typical superimposed basin. On the basis of combination with the static framework of monotypic basin and the dynamic superimposition of multi-phase basin, the conception of basin superimposing units is brought forward. The eastern North China basin has six types of superimposing units. Analysis of petroleum geological conditions of the basin superimposing units shows that Ⅱ2 and Ⅱ4 are the favorable exploration areas where the oil and gas came from the hydrocarbon source rocks of Palaeozoic; andⅠand Ⅱ2 are the favorable exploration areas where the oil and gas came from the hydrocarbon source rocks of Mesozoic. This paper provides a new idea of correct analysis and evaluation of the petroleum geological conditions of superimposed basins.oft-com:office:office" />
