郯庐断裂与渤海海域反转构造及花状构造

郯庐断裂在渤海海域不同区域的展布及其特征有所差异,渤中凹陷以南表现为多支,渤中凹陷及其以北地区表现为单支,在断裂各分支及其附近形成了花状构造、正反转构造、潜山构造等一系列有利于油气聚集的构造圈闭.文中再次提出“辽东凸起—渤东低凸起带”是发育于郯庐断裂带上的一系列构造带,而不是凸起带.郯庐断裂的活动对渤海海域油气聚集有至关重要的影响.

RELATIONSHIP OF TANLU FAULT TO THE INVERSION AND FLOWER STRUCTURES IN BOHAI BAY

Tanlu fault displays different characters in different areas in Bohai Bay. Branchs of the fault and aruond them appear flower structures, positive inversion structures and buried hill structures. They are good structural traps for hydrocarbon accumulation. Author proposes again that real meaning of " Liaodong uplift- Bodong low uplift" is a series of structure zones along Tanlu fault, not uplift belt. Activities of Tanlu fault significantly affected on hydro carbon accumulation in Bohai Bay.
