摘要
为确定高邮凹陷北斜坡戴南组油藏的成藏期次,采用流体包裹体测温技术,对研究区3口井的流体包裹体特征和均一温度进行了分析。结果表明,该区戴南组储层流体包裹体分为盐水包裹体和有机包裹体;均一温度呈1期连续分布,主峰温在90～100℃。根据包裹体均一温度、地层埋藏史和热史,推测该区戴南组油气成藏时对应的地质年代约为垛二段沉积末期。结合圈闭发育史和烃源岩生排烃史等分析,最终确定研究区戴南组为1期成藏,时间为垛二段沉积末期。
The fluid inclusion tempreture measuring is used for the determination of she hydrocarbon accumulation stages of Dainan Formation in the Northen Slope of Gaoyou Depresstion. The characteristics and the homogenization temperature of the fluid inclusions in 3 wells were analyzed.It is found that the fluid inclusions in the reservoirs include brinish inclusions and organic inclusions,and the homogenization temperature of the fluid inclusions in this region distributes continuously in one ranges of 90- 100℃ The hydrocarbon-infilling stages in the area according to the reservoir burial history,homogenization temperature of the fluid inclusions and thermal history of source rocks. Their corresponding geologic epoch is the end of deposition of Sanduo Formation .Combined with trap development history and hydrocarbon generation and expulsion history of source rocks,we know that there was only one times of hydrocarbon accumulation and reservoir formation,and the epoch is the end of deposition of Sanduo Formation.
