摘要：

通过已知油气藏的分析,冀中地区第三系碎屑岩油气藏的供油方式有两种:一是断面供油;二是层状渗透层供油。导油断层不仅控制圈闭的形成和储集体的分布,还直接控制油气运移路径。层状渗透层供油受构造高点控制,运移路径一般为垂直构造等高线沿鼻状构造的鼻梁向构造高点运移。按“顺瓜找藤,再顺藤摸瓜”的思路,沿油气运移途径的圈闭是最有利的油气成藏场所。因此,紧靠导油断层的构造中低部位和鼻状构造的鼻梁带是下步滚动开发的最有利部位。

Abstract:

There are two kinds of oil supply ways in the Tertiary clastic rock oil reservoirs in Jizhong Region:one is fractured surface supply oil;the other is bedded permeable layer supply oil.Oil diverting faults did not only control trap formation and reservoir distribution,but also controlled the migration paths.The bedded permeable layer supply oil is controlled by structural hights,the migration paths are usually the counter lines of vertical structures,and oil migrates towards the height of noze structure along the noze bridg.The traps along oil and gas migration paths are favourable for hydrocarbon pool formation.It thus suggested that the middle and the lower parts close to oil diverting fault and the bridge of the noze structure are most favourable for future rolling exploration.

Key words: Jizhong Region, oil-providing condition, complex block, rolling exploration, oil diverting fault, nose zone
