摘　　要：陈官庄地区平面上主要发育北东向、近东西向和北西向断裂,剖面上主要发育断阶、地堑和地垒等断层组合。断裂演化受扭张作用的控制,根据断裂特征,将断裂带的演化分为前第三系沉积期、孔店—沙四段沉积期和沙三段沉积期3个阶段。断裂是研究区的主要构造现象,不同断裂组合形成了不同的构造样式,构造样式决定了不同的圈闭类型,而断裂起到了沟通油源、控制油气运聚及富集的作用。The fractures in NE, EW and NW are mainly developed in horizontal, the fault complexes （fault step, graben, and horst, etc.） are mainly developed in vertical direction in Chenguanzhuang area. The evolution of fault belt is controlled by the transtension, according to the fracture features, the evolution of fault belt is divided into three depositional stages （Tertiary system depositional stage, Ek-ES4 depositional stage and ES3 depositional stage）. The fracture is a main structure appearance in the area, the different structure styles are formed by the different fault complexes, the trap types depend on the structure styles, and the fault plays a role of connecting oil sources, controlling hydrocarbon transport and accumulation.
