| 摘 要： | 综合利用断裂和圈闭发育史、油藏饱和压力、烃源岩主生排烃期、储层流体包裹体均一温度等方法对东濮凹陷濮卫洼陷油气成藏期进行了分析,并提出对于存在剥蚀厚度比较大的地区在利用饱和压力方法计算成藏期时应结合埋藏史。研究认为,该区主要为两期成藏,分别为古近纪末期和新近纪末期—第四纪,且东西两侧油气成藏期存在差异,东侧濮城地区两期成藏,在古近纪末期和新近纪末期—第四纪均发生油气充注成藏,而西侧卫城地区仅在古近纪末期存在油气充注成藏,为一期成藏。

| Abstract: | Based on fault and trap development history,reservoir saturated pressure,hydrocarbon-generated and hydrocarbon-expulsed process of hydrocarbon source rock,reservoir fluid inclusion homogenization temperature,the formation stages of oil-gas reservoirs in Puwei Subsag,Dongpu Sag are discussed,and calculating the formation stages of oil-gas reservoirs with saturated pressure should be combined with burial history for the area,in which the denudation is thicker.The results show that the accumulation phases of oil and gas reservoirs in Puwei Subsag are divided into two phases,Late Paleogene phase and Late Neogene-Quaternary phase;the petroleum accumulation phases in the oil and gas reservoirs are different between the eastern and western reservoirs;hydrocarbon charging times in the eastern reservoir are Late Paleogene phase and Neogene-Quaternary phase,but the time in the western reservoir is only Late Neogene. |
