摘要(Abstract)：
文南油田位于河南东濮凹陷中央隆起带向南的倾伏端,紧邻前梨园生油洼陷。研究区构造面积约55km2,是极为有利的油气聚集带。古近系沙河街组一段下亚段(Es1x)是该油田开发中的一个主要接替层系,油藏类型属于岩性、断层岩性和断块型油藏,油气聚集受砂体展布和断裂输导系统的控制。砂体展布受物源区性质和古沉积环境制约,因此,沉积微相与油气分布有密切关系。储集层主要发育在前梨园—席城集以西、胡状集—庆祖集以东地区,属于三角洲前缘水下分流河道、河口坝及前缘席状砂沉积。水下分流河道及河口坝砂层较厚,约4—7m,研究区分布广泛。研究区还存在分布广泛而稳定水下分流河道侧缘、河口坝侧缘以及席状砂砂体,砂层较薄,厚约2—3m。在水下分流河道的主河道沉积中,微相油层的层数多、厚度大,因此当其与构造高点得到合理配置时,常形成高产油流聚集区。
