| 摘 要： | 在分析盐城凹陷构造演化史、朱家墩构造圈闭发育史和盐城凹陷主力烃源岩生、排烃特征的基础上,系统研究了朱家墩气藏K2t(泰州组)储层流体包裹体类型、分布特征和均一温度。研究表明,K2t储层流体包裹体明显分为盐水包裹体和有机包裹体;均一温度明显分为两期(即渐新世晚期和新近纪末期)。结合构造演化史、圈闭发育史和生、排烃史,并经综合分析认为,在渐新世晚期和新近纪末期,朱家墩气藏有过两期主要的油气充注,且以第2期充注为主。

| Abstract: | This paper discusses the distribution type,characteristics and homogenization temperature of fluid inclusion in reservoir systematically on the basis of analyzing the tectonic evolution of Yancheng Depression,the trap formation and evolution of Zhujiadun structure and the genetic and expulsive characteristics of main source rock in Yancheng Depression.It shows in our study that the fluid inclusion in K_2t reservoir can be obviously classified into saline water inclusion and organic inclusion and the homogenization temperature,and can be obviously classified into two stages(the corresponding geological time is Late Oligocene and the end of Neogene).Combing with the tectonic evolution hydrocarbon history ,trap development history and genetic and expulsive hydrocarbon history,it is thought there are two stages gas filled in Zhujiadun gas reservoir in Late Oligocene and the end of Neogene,between which the Late one is more important. |
