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
Through the analysis of known oil and gas reservoirs, there are two kinds of oil supply methods for Tertiary clastic reservoirs in Jizhong area: one is oil supply in section; the other is oil supply in layered permeable layer. The oil-bearing fault not only controls the formation of trap and the distribution of reservoirs, but also directly controls the hydrocarbon migration path. Layered permeable bed oil supply controlled by the structural high point, the migration path is generally vertical structure contours along the nasal nose structure to the structural high point of migration. According to “follow the melon to find the vine, and then follow the melon” idea, traps along the hydrocarbon migration route is the most favorable oil and gas accumulation place. Therefore, the structure of the oil-bearing fault in the lower part of the nasal bridge structure and the nose is the next step rolling development of the most favorable site
