渤海海域渤东地区新生代断裂特征及对油气的控制
|
摘要
由于郯庐断裂带控制着渤海盆地渤东地区断裂构造特征及油气聚集,在精选4条二维测线及PL2-2和LD32三维区块精细解释的基础上,系统研究了渤东地区新生代构造变形特征及郯庐断裂带对油气的控制作用。结果表明,渤东地区在平面上整体呈"入"字型排列,并由渤东1号断层及渤东2号断层组合发育成复合堑-垒结构,由此区域分为南、中、北3个区。郯庐断裂带在渤东地区的3个分支整体控制着渤东地区断裂的形成及演化。由三维地震资料精细解释渤东地区断裂系统为古近纪伸展断层系统和古近纪末期-新近纪走滑断层系统的叠加复合。渤东地区断裂演化影响烃源岩的分布与热演化,控制油气的运移及圈闭的形成,渤东低凸起及渤东凹陷中央走滑带形成的反转构造以及渤东凹陷东斜坡是有利的油气聚集带。
As to the Tanlu fault zone controlling the tectonic characteristics and hydrocarbon accumulation in Bodong area,this paper systematically studies the Cenozoic tectonic characteristics and the Tanlu fault zone controlling hydrocarbon accumulation in Bodong area on base of the explanation results of four seismic sections and 3D seismic data.The result indicates that the whole of Bodong area shows the shape of "入",the Chinese character "Ru" and mainly Bodong No.1 fault and No.2 fault make up complex graben-horst structure,which divide into the south and middle and north zone.The three branches of the Tanlu fault control the fault formation and evolution in Bodong area.The explanation results of 3D seismic data in Bodong area show that the Cenozoic fault systems combine with the normal fault system in the Paleogene and the strike-slip fault system in the Neogene and the Quaternary.The formation and evolution of branches of Tanlu fault controlled generation,migration and accumulation of hydrocarbon.The slope zone and central salient with growing long-term active faults become the advantage zone of hydrocarbon accumulation.
