| 摘 要： | 通过采集泌阳凹陷王集-新庄地区岩心样品,对其中包裹体进行盐度特征分析、镜下观察及均一温度测定;结果表明王集-新庄地区包裹体分为两期,与盆地埋藏史和热史研究划分的早、晚两个成藏期相对应。结合生排烃史综合分析,该区油气分两期成藏,早期油气成藏期主要发生在核一段末期~廖庄组沉积期,为小规模油气成藏,该期主要生成低熟油;晚期油气成藏期主要发生在廖庄末抬升期,为大规模油气成藏,是形成现今油田的主要成藏期。利用油气包裹体进行油气成藏研究,必须和宿主矿物的矿物岩石学分析及其他成藏期次分析方法结合使用,才能使分析结果更加客观可信。

| Abstract: | Study of fluid inclusions indicates that burial and thermal evolution of the basin may be divided into two stages in the Wangji-Xinzhuang region which are corresponding with the early and late accumulation stages. The early hydrocarbon accumulation occurred mainly in the end of Ehl or sedimentary period of the Liaozhuang Formation with a small-scale oil and gas accumulation with low mature hydrocarbon generated. The late hydrocarbon accumulation occurred mainly in uplifting of the last Liaozhuang period with a large-scale oil and gas accumulation. This is the main accumulation period. |

| Keywords: | Salinity of fluid inclusion homogenization temperature accumulation stage Wangji-Xinzhuang |
