主 题：Africa sedimentary basin hydrocarbon distribution
摘 要：There are eighty sedimentary basins in five different types in African continent,*** sag basin,foreland basin,intermountain basin,passive margin basin and rift basin,which underwent the stress environment of stable *** first three types of basins had been intensely influenced by Hercynian and Alpine tectonic movement,while the later two types of basins always exist in a stable extension *** basin evolution caused the obviously hydrocarbon distribution *** North Africa,marginal craton sag and rift basins show great expedition potential of hydrocarbon,marginal craton sag basins had good formation and preservation of Lower Silurian hot shale,tectonic-strata traps and migration pathway formed by Hercynian unconformity,and rift basins had excellent Upper Cretaceous marine source rocks and good hydrocarbon preservation with little tectonic ***,in the salt-containing passive margin basins and delta basins of West Africa,thick strata containing high quality source rocks and plastic strata were well *** rocks of high maturity,good hydrocarbon preservation,growth faults and deformational structure traps were formed by abundant overlying sediments and sources supplied from Tertiary large water system.
