通过油藏解剖和油成藏条件空间配置关系,对宋站南地区扶杨油层油运聚成藏机制和主控因素进行了研究,得到宋站南地区扶杨油层油主要来自青一段源岩。油源区内扶杨油层油运聚成藏模式为:三肇凹陷青一段源岩生成的油在超压作用下通过T2源断裂向下“倒灌”运移进入扶杨油层后,再在浮力作用下沿断裂向高断块圈闭进行短距离的运聚成藏。油源区外扶杨油层油运聚成藏模式为:三肇凹陷扶杨油层中的油在浮力作用下沿被断裂沟通的砂体侧向运移至宋站南地区,在断层上升盘圈闭中聚集成藏。油源区内扶杨油层油成藏主要受以下3个因素控制:①青一段源岩生成的油向下“倒灌”运移区控制着油藏形成与分布区域;②T2源断裂控制着油运聚的部位;③断裂上升盘是油聚集的主要场所。油源区外扶杨油层油成藏主要受以下2个因素控制:①位于运移路径上或附近的圈闭才能形成油藏;②断裂上升盘有利于油藏形成。综合上述研究可以得到油源区内T2源断裂附近和油源区外运移路径附近的断裂上升盘应为油勘探的有利目标。 Through the relationship between reservoir anatomy and spatial distribution of oil accumulation conditions, the mechanism of oil accumulation and main controlling factors of oil migration in Fuyang reservoir of Songzhannan area are studied. The oil from Fuyang reservoir in the south of Songzhan area is mainly from the source rocks . The oil accumulation and accumulation pattern of Fuyang oil layer in the oil source area is that the oil generated from the source rock of the Qingyuan area in the Sanzhao depression passes through the T2 source fracture to the bottom and backslides into the Fuyang reservoir under the action of overpressure Under the action of buoyancy, faults are transported to the high fault blocks for short-distance migration and accumulation. The oil accumulation and accumulation model of the oil reservoirs outside the Fuyuan oil reservoir is that the oil in the Fuyang oil layer of the Sanzhao depression migrates laterally along the fault-communicating sand bodies to the Songnan area along the buoyancy, Closed accumulation of accumulation. The oil accumulation in the Fuyang oil layer in the oil source area is controlled mainly by the following three factors: (1) the oil generated from the source rock of the Qingyi Member controlled the formation and distribution of oil reservoirs in the downfall; the T2 source fracture controlled Oil accumulation site; ③ fracture rise plate is the main site of oil accumulation. Oil reservoirs outside Fuyuan oil reservoir are mainly controlled by two factors as follows: ① the traps located on or near the migration path can form reservoirs; ② the fault rising trays are conducive to reservoir formation. Based on the above studies, we can get the favorable target of oil exploration by the fault rising plate near the source rocks in the oil source area and the outer source migration path in the oil source area.
