根据地震资料和断层的位移-距离曲线，对辽东湾坳陷中部金县构造变换带的发育特征进行了分析。金县构造是一个发育在走滑断层叠置段内的大型含油气构造，属于郯庐走滑断裂带组成部分的辽中1号断裂带的两条分段断裂在金县地区发生相互作用和叠置，形成了在平面上呈菱形展布的走滑双重构造。菱形断块体同时也传递了分段断层的位移量，使其在空间上保持守恒，从而形成了金县斜向背斜型构造变换带。金县构造变换带的形成演化主要经历了孤立断层发育、变换带初始形成、变换带复杂化和变换带破裂4个阶段。针对渤海地区不同类型构造变换带进行深入分析，对指导油气勘探具有重要意义。

Based on seismic data and displacement-distance scaling,this paper analyzes the formation of the JX transfer zone in the middle part of the Liaodongwan depression.The oil-bearing JX structure is a large-scale strike-slip duplex structure where two segmented faults of the Liaozhong-No.1 strike-slip fault overstep and inter-act each other.The rhombic faulted block between the two segmented and overstepped faults transferred their displacements,and the conservation of fault displacements formed the JX transfer zone which belongs to the type of oblique anticline.The JX transfer zone experienced four evolution stages,including the isolated faults,trans-fer zones initiation,complication and rupture.The integrated study on transfer zones has important significance to oil and gas exploration in the offshore part of the Bohai Bay basin.
