    Genetic Origin of CO2-Rich Oil Reservoirs and Pool-Forming Period in Melut Basin, Southern Sudan

    • 摘要: Palogue油田的发现打开了Melut盆地古近系勘探新方向,证实了北部凹陷为富油气凹陷.Palogue油田具有以下白垩统为主力烃源岩,古近系为主力成藏组合的跨时代运聚风格,幔源CO2气体对油气的聚集和改造具有不可忽略的作用.通过对CO2气体、原油特征、生标特征、包裹体特征进行研究,结合地层埋藏史,分析油气特征及成藏期次.结果表明:Palogue油田具有两期成藏的特征,古近纪中期发生第1期油气成藏事件,随后原油被降解;古近纪晚期-新近纪以来,伴随幔源CO2气体油气发生第2次运移充注事件,且CO2气体对油藏进行了强烈的气洗作用.
