Title: Potential replacement regions of hydrocarbon reserves in exploration domain of foreland basins
Abstract: foreland basins of central and western region of China are rich in oil and gas resources,so strengthen research on new exploration regions of foreland basin is important. Oil and gas exploration in foreland basins is more concentrated in six districts of extrusion anticline structure,lithologic traps,reef,drape anticline,stratigraphic traps and fault traps. extrusion anticline structure is major style,but its exploration is more and more difficult. Reference to important great discoveries in global exploration and combined with new trend of exploration breakthrough in foreland basins domain of China,this paper brings forward three potential replacement regions of hydrocarbon reserves,which is the concealed sequences under metamorphic rock thrust nappe of orogenic belt,the footwall thrust clamping piece structures of foreland thrust belts,the deep formation of foreland depression. three potential replacement regions of hydrocarbon reserves have biggish hydrocarbon exploration potential and have same petroleum geological conditions to foreland depression sequences. The concealed sequences under metamorphic rock thrust nappe of orogenic belt developed basin-forming period sedimentary sequence. The footwall thrust clamping piece structures of foreland thrust belts have favorable reservoir and seal condition. deep formation of foreland depression provided high quality source rock and reservoir. Exploration practices approved that these three potential replacement regions of hydrocarbon reserves have widely exploration prospect.
