Abstract:

Tectonic migration is a very common geological phenomenon in the process of basin evolution. The characteristics of tectonic migration in Qinnan sag are of great significance for understanding its hydrocarbon accumulation regulation. This study explores the effect of tectonic migration on hydrocarbon accumulation by analyzing the Cenozoic activity, spatiotemporal distribution characteristics of the main controlling boundary faults of each subsag in Qinnan sag, and migration of the depocenter and subsidence center of subsags in various periods. The research suggests that the activity intensity of the main controlling boundary faults in each subsag is significantly different; the tectonic migration in subsags can be divided into two types: self-migration and hetero-migration, characterized by migration from north to south and from west to east; the tectonic migration is reflected in the change of tectonic style, difference in the activity intensity of the main controlling boundary faults and multistage episodic tectonism. The migration of the depocenter and subsidence center in Qinnan sag results from the combined action of extensional strike-slipping and extensional rifting of the large boundary faults in each subsag. Tectonic migration can provide a space for source rocks, influence and control the distribution of source rocks, promote the migration and accumulation of hydrocarbons, and cause differences in petroliferous property of subsags in the horizontal and vertical enrichment layers. The hydrocarbon-rich conditions are different for each subsag in Qinnan sag. There are abundant hydrocarbons in the southeastern subsags, poor exploration degree in the western subsags, and great exploration potential in the eastern subsags.

Key words: depocenter, subsidence center, tectonic migration, hydrocarbon accumulation, Qinnan sag, Bohai Bay Basin

摘要：

构造迁移是盆地演化过程中十分普遍的地质现象。秦南凹陷的构造迁移特征对其油气聚集规律的认识具有重要意义。通过分析秦南凹陷各洼陷主控边界断裂在新生代的活动性、时空展布特征以及洼陷在不同时期沉积中心和沉降中心的迁移，探讨构造迁移对油气聚集的影响。研究认为：各洼陷的主控边界断裂的活动强度具有明显的差异性；洼陷的构造迁移分为"自迁移"和"异迁移" 2种类型，具有从北向南、从西向东迁移的特征；构造迁移体现在构造样式的变迁、主控边界断裂活动强度的差异以及多期次幕式构造活动上。秦南凹陷沉积中心和沉降中心的迁移是各洼陷边界大断裂伸展-走滑与伸展-断陷共同作用的结果。构造迁移可为烃源岩提供可容纳空间，影响和控制烃源岩的分布，促进油气的运移和聚集成藏，并造成洼陷的含油气性在平面及纵向富集层系上的差异。秦南凹陷各洼陷的富烃情况有所不同：东南洼是目前已探明的富生烃洼陷；西洼的探明程度较差；东洼为潜在富烃洼陷，具有很大的勘探潜力。
