Characteristic analysis and initial understanding of hydrocarbon distribution of foreland basins in the world

Foreland basin is the richest in oil and gas distribution of the world's different petroliferous basins.It has more favorable petroleum geology conditions and greater exploration potential.In this paper,the authors compare and analyze the coupling relationship between basins and adjacent mountains of foreland basins and the controlling factor of oil and gas,then acquire the initial understanding of the oil and gas reservoir characteristics foreland basins.That the structure of foreign typical foreland basin is a single,generally superimposed over a passive continental margin or back-arc basins.While the basement structure of Chinese central and western foreland basins is of much complexity,multi-stage evolution and more cause types.The distribution of oil and gas is related to the development characteristics of the fold-thrust belt.
