摘要
依据上第三系的石油地质条件 ,设计了比较符合实际的地质模型。通过模拟实验 ,深化了油气运移、聚集机理 ,明确了馆下段块状砂岩及馆陶组内部次级断层作为油气运移疏导体系的作用 ,指出了馆下段顶部低幅度构造油藏和馆上段、明化镇组以岩性、地层为主控因素且与次级断层相连通的隐蔽油气藏是胜利油区今后上第三系油气勘探的重点 。
On the basis of petroleum geological conditions of Neogene, the geologic model according with practice fairly is designed. Through simulating test, the mechanism of hydrocarbon migration and accumulation is deepened. The massive sandstone in Guan downsection and secondary fault with Guantao group play hydrocarbon migration and systemdredging role, and it is determined. The lowamplitude structure reservoir in Guan downsection top and subtle reservor in Guan uppersection will be future exploration key points in Neogene of Shengli petroliferous area, and good results have been obtained in exploration practice.
