| 摘 要： | 源岩、盖层及断裂为东营凹陷深层天然气成藏的主要要素,其深层烃源岩主要分布于沙三下亚段、沙四上亚段及孔二段,主要区域盖层为沙三中下部厚层泥岩、油页岩.烃源岩大量排气期、盖层封闭形成期、断层活动期的时间匹配关系研究表明,东营凹陷深层盖层封闭的形成时期早于烃源岩的大量排气期,断层的活动时期早于盖层封闭的形成时期,对深层天然气的聚集成藏有利.源盖断时间匹配关系表明,北部利津-民丰洼陷为深层天然气勘探的有利地区.

| Abstract: | Source rock,cap rock and faults are the main accumulation factors of the deep gas in Dongying Depression.The lower part of the third member,the upper part of the fourth member of Shahejie Formation and the second member of Kongdian Formation are the main source rocks,and the grey mudstone and oil shale in the middle and lower parts of the third member of Shahejie Formation consists of the regional caprock of high quality.The analysis of the time matching relation among the expulsion hydrocarbon period of so... |
