摘要
为了揭示渤海湾盆地板桥凹陷内部新生代断裂构造与油气关系,利用油区构造解析理论对板桥凹陷新生代断裂构造发育及演化特征进行研究。综合生储盖组合、断裂构造以及油气分布特征,总结断裂活动对油气成藏各要素的控制作用。研究结果表明:板桥凹陷可划分为北部复杂断裂褶皱带、中部大型断鼻构造带以及南部雁列式走滑变形带3个具有明显不同的新生代构造变形组合特征的区段,新生代断裂活动主要发生在沙一下—沙一中亚段以及东营组沉积时期,构造演化具有明显的继承性。板桥凹陷在不同区段的构造变形特征造成了油气成藏模式的差异性。
In order to reveal the relationship between the Cenozonic fault structure and hydrocarbon distribution of Banqiao sag of Bohai Bay Basin, the development and evolution of the fault structure were researched by using the oilfield structural analysis method. Based on comprehensive research of source-reservoir-caprock combination, fault structure and the hydrocarbon distribution, the control of fault activity on hydrocarbon accumulation was summarized.The results show that the sag can be divided into three different segments based on their Cenozoic deformed structure assemblages, i.e. the complex faulted fold in the north, the large faulted nose belt in the central and en-echelon strike-slip deformation belt in the south. The evolution of Cenozonic fault structure mainly developed in the period of lower Es1-middle Es1 and Dongying formation has obvious inheritance. The structure deformations in different segments of the Banqiao Sag result in the difference of various hydrocarbon accumulations.
