苏北盆地富民油田阜宁组储层长石石英砂岩储层发育烃类和盐水包裹体。通过显微荧光观察，储层中石英颗粒加大边与石英颗粒微裂隙硅质胶结物的烃类包裹体明显不同，前者荧光主要为灰黄色与淡黄色，后者则为蓝色与蓝白色。根据与烃类包裹体伴生的盐水包裹体均一温度法和地质综合分析结果，阜宁组储层发育两期油气充注，早期充注时间为53～46 Ma，晚期为45～30 Ma。

Hydrocarbon and brine inclusions developed in arkose quartzite reservoir of Funing group of Fumin oilfield in North Ji-angsu basin. By microscopic fluorescent observation, quartz grains oversize boundary in reservoir is clearly different from the hydro-carbon inclusion of quartz grains microfissure siliceous cement. The florescence of the former are mainly the grayish yellow and faint yellow, while that of the latter are bule and blue-white. According to the homogenization temperature method and comprehen-sive geological analysis results of the brine inclusions accompanying with the hydrocarbon inclusions, two-step hydrocarbon filling developed in Funing group. The early filling time is 53~46 Ma while the later time is 45~30 Ma.
