| 摘 要： | 通过流体包裹体的透射光和荧光镜下观察、包裹体均一温度测定,对南堡凹陷下古生界碳酸盐岩流体包裹体特征及油气成藏期进行了研究。结果表明:南堡凹陷下古生界碳酸盐岩储层流体包裹体较为发育,主要在碳酸盐岩脉中沿愈合裂缝呈带状分布,烃类包裹体在荧光下呈黄白色--蓝白色,说明研究区油气成熟度相对较高;由包裹体均一温度实测结果可知,该区包裹体均一温度具有明显的双峰特征,峰值分别为70℃~80℃和130℃~140℃;结合埋藏史和热演化史进行综合研究,认为研究区下古生界碳酸盐岩储层主要经历了两期油气充注,第一期为25~22 Ma(东营末期—馆陶早期),第二期为8~5 Ma(明化镇中期)。

| Abstract: | Based on observations of transmission light and fluoroscope as well as on measuring of homogeniza- tion temperature of fluid inclusions，the characteristics of fluid inclusions and hydrocarbon accumulation phases of the Lower Paleozoic carbonate reservoir in Nanpu Depression are discussed． The results indicate that the fluid inclu- sions are relatively abundant with zonal distribution along the healed fracture in carbonate veins of Nanpu Depres- sion． Organic inclusions present yellowish white and blue- white fluorescents，which indicates a higher maturity of oil and gas in this area． Homogenization temperatures measured in aqueous inclusions associated with hydrocarbon ones show a bimodal distribution with 70℃ ～80℃ and 130℃ ～140℃ as double peaks． Combined with burial his- tory and thermal evolution history，the Lower Paleozoic carbonate reservoirs in Nanpu Depression experienced two hydrocarbon accumulation phases，corresponding to 25 ～22 Ma (from the late Dongying stage to the early Guantao stage) and 8 ～5 Ma (the middle minghuazhen stage)． |
