摘要
运用平衡剖面和去压实校正原理,从几何学、运动学的角度,对济阳坳陷沾化凹陷的渤南地区新生代构造特征及演化进行了研究。结果表明:①渤南地区新生代以发育盆倾的盖层滑脱正断层为主要构造特点,由于基岩和边界断层的影响,东部和西部的构造有明显差异。②新生代构造演化可以分为古近纪断陷阶段和新近纪、第四纪坳陷阶段,孔店组至沙三段沉积时期是主要的断陷期。③构造运动控制了圈闭的分布和类型,第三系油气圈闭主要分布在陈家庄凸起北斜坡向北凸出的部位,且自南而北分别由以地层圈闭为主过渡到以构造圈闭、构造-岩性圈闭为主。在圈闭的空间分布上,坡折带以南的斜坡上部以地层圈闭为主;坡折带附近及深洼区以构造圈闭和构造-岩性圈闭为主。
Based on the balanced section and the decompaction correction principle, the tectonic evolution of Cenozoic in the Bonan Region is analyzed from tectonic geometry and movement. The marginal slip normal faults are the main feature of the structure. Influenced by basement rocks and border faults, the structures in the west and in the east are obviously different. The Cenozoic tectonic evolution is divided into Paleogene faulting episode, Neogene depressing episode and Quaternary Depressing episode. The period between Ek and Es3 is the primary faulting phase. The tectonic movement controls the distribution and type of traps. The Tertiary traps mainly occur in the northward bulge in the northern slope of the Chenjiazhuang uplift, with the stratigraphic trap in the south and the structural and structural lithologic traps in the north. The stratigraphic trap is the main type in the upper position of the slope south of the slope break, while the structural trap and the structural-lithologic trap dominate in the deep water area and the in the vicinity of the slope break.
