| 摘要: |
| 根据含氮化合物的分布特征,对周返断裂构造带各M位原油注入点位置与油气运移特征进行研究。结果表 明:含氮化合物总含讀在周11并到周丨3井之间呈现为高值，屏蔽塑二甲基咔唑明显富集，l,8-/2，7-DlVlC等比值 参数均有所增加，原油的注入位置位于周11井至周丨3井之间；以这两口井的区域为中心，洼陷内生成的油气向地 层抬升方向上发生明迠运移，表现出短距离侧向运移的特征，决定了研究区油气运移聚集模式主要为自生自储的 成藏模式。 |

| Abstract: |
| Based on the distribution rharautenzatiun of nitrogen compouiKls, the crude oil charge position and migration characterization in each layer of Zhoufan fault zone were studied. Tlie results show that the total nitrogenous compounds content from wells ZHou 11 to Zhou 13 is high and screened dimethyl carbazole tends to concentrate with 1 ,B-/2,7-DMC values increasing significantly. The hydrocarbons are charged between wells Zhou 11 and Zhou 13. Around the area of the two wells， the hydrocarbon generated in the depression migrates towards the stratigraphieally uplifting direction, as it is charartftrized by laterally migrating for a short distance, and it determines that the migration and concentration of hydrocarbon in this area is self-generated and self-accumulated model. |
