渤海湾盆地惠民凹陷临北地区帚状构造物理模拟实验研究
|
摘要
渤海湾盆地惠民凹陷地质构造复杂。以惠民凹陷临北地区帚状构造为主要研究对象,通过大量地质、钻井及地震资料研究,建立了该区典型帚状构造发育的地质模型,应用构造物理模拟手段对帚状构造发育的古应力环境进行了构造变形的动态过程模拟实验。实验结果证明,临北帚状构造受控于右旋走滑构造应力场;基于此,自北而南发育形成了多组北东向呈雁列式展布的正断层;呈现为自北而南、自撒开端向收敛端的演化序列。且从沙四期始到东营组发育期,构造活动呈现了弱—强—较强的变化规律,从而控制了洼陷沉积和主要三角洲(鼻状构造)的发育和迁移。
Geological structure is very complicated in the Huimin Sag of the Bohai Bay Basin.The brush structure in Linbei area of the Huimin Sag was studied.Based on geologic,logging and seismic data,a geological model for the generation of typical brush structure in the study area was established.The paleo-stress circumstance when the brush structure developed was simulated through the dynamic modeling of tectonic deformation.The brush structure in Linbei area was controlled by the dextrorotatory strike slip tectonic stress field.Several sets of NE oriented echelon normal faults generated from north to south.The evolution sequence was featured by opening in the north and closing in the south.During the period from Es4 to Ed,structural activity changed from weak to strong and then to relatively strong,controlling sediment and the generation and migration of main deltas(nose structures).
