| 摘 要： | 通过油藏解剖和其与成藏条件时空配置关系分析，在总结长10区块扶余油层油运移机制及模式的基础上，对其运移输导通道及其对油成藏与分布的控制作用进行了研究，得到长10区块扶余油层油运移输导通道主要包括①T2源断裂是三肇凹陷青一段源岩生成的油向下伏扶杨油层“倒灌”运移的输导通道；②T2断裂配合砂体是三肇凹陷扶杨油层中油向长10区块侧向运移的输导通道。长10区块扶余油层油运移输导通道对油成藏与分布的控制作用主要表现为①T2源断裂发育程度控制着三肇凹陷向长10区块扶余油层油供给量；②T2断裂密集带是长10区块扶余油层油聚集的主要区域，被T2断裂配合砂体形成的输导通道连接的高断块是油聚集的主要部位。

| Abstract: | Through oil reservoir anatomization and analyzing its spatial-temporal relationship with reservoir forming condition, migration pathways and the control on oil accumulation and distribution were studied on the basis of summarizing oil migration mechanism and mode in Fuyu oil layer in Chang 10 block. It was considered that oil migration pathways of Fuyu oil layer in Chang 10 block were as follows in main. ①T_2 source faults are transporting pathways through which oil that generated by K_1 qn_1 source rock migrated downward into underlying F, Y oil layers in Sanzhao depression. ②Faults combining with sand bodies are transporting pathways of oil in Fuyu oil layer in Sanzhao depression migrating laterally to Chang 10 block. The controlling roles of oil migration pathways of Fuyu oil layer in Chang 10 block to oil accumulation and distribution are mainly manifested as: ①Development degree of T_2 source faults controis oil supply amount of Fuyu oil layer in Chang 10 block. ②Fault concentrated belts are main oil accumulation areas of Fuyu oil layer in Chang 10 block, and high fault block connected by transporting pathways that formed by faults combing with sand bodies are main oil accumulation positions. |
