根据三维地震资料和钻井资料的联合解释，结合平衡剖面技术，对渤海湾盆地长堤地区主要断裂及其伴生构造的地质特征进行研究。结果表明，长堤地区发育各种不同尺度和性质的断层，绝大多数断层属于生长断层。断裂活动受到“济阳运动”和“东营运动”的影响，具有幕式活动的特征。长堤地区规模较大的两期不整合界面的形成与断裂的幕式活动关系密切。沉积地层中形成的多期不整合界面，体现了长堤地区在新生代演化中经历了多旋回断陷作用。根据对长堤地区重要界面的识别以及结合区域沉降史分析，将其构造演化划分为褶皱隆升、伸展断陷和稳定沉降3个主要阶段，其中伸展断陷阶段进一步分为沙三期-沙二期的断陷I幕，沙一期-东营期的断陷II幕。长堤地区的油气圈闭类型主要受到断裂活动的控制，同时也受到其演化的影响。

The main fault and its associated structures in Changdi Area of the Bohai Basin are studied according to its 3D seismic data,drilling wells by using balanced section technique. The result shows that a variety of scales,shape and properties of the fault are developed in Changdi Area,the majority of which belong to growth fault. Fault activity has the characteristics of episodic by the influences of the Jiyang Movement and the Dongying Movement. The larger two unconformity interfaces are closely related to the fracture episodic activities in Changdi Area. The multi-phase unconformity interface reflects the tectonic evolution of the experience of polycyclic depression in the Cenozoic. According to the analysis of the major balanced cross section and identification of the important interface,and combined with regional subsidence history,the tectonic evolution of the Changdi Area can be divided into three stages:fold formation stage,fault depression stage and stable settlement stage. Fault depression stage can be further divided into episode I in Eocene(E2s3-E2s2)and episode II in Oligocene(E3s1-E3d). Hydrocarbon trap are mainly controlled by fault activities,and meanwhile under the influence of its tectonic evolution.
