通过对塔里木盆地玉北地区最新的三维地震资料进行解释分析，运用断层的位移－距离分析方法，探讨了玉东3断裂带的转换带特征，并分析了转换带形成的三个阶段。玉北地区断裂发育，主要为北西走向。由北向南，玉东3断裂带从北东段到南西段断层倾向由 SE 向逐渐变为 NW 向，根据这种变化及其剖面组合关系，采用 Morley 对转换带的分类方案，确定在转换段内形成了聚敛叠覆型转换带。转换段的转换带传递了北东段断层和南西段断层的位移量，使玉东3断裂带的总位移量保持一致。该转换带的形成演化主要经历了孤立逆断层、转换带形成和转换带复杂化等三个阶段。

Based on the interpretation of the latest 3D seismic profiles,this study discussed the characteristic and evolution of the transfer zone in Yudong 3 fault belt in Tarim Basin according to the analysis of displace-ment-distance method.The Yubei area mainly consists of a number of faults striking northwest.From the north-east section to the southwest section,the direction of the main fault gradually changed from southeast to north-west.According to the combination and intersection relations of fault structures in this area,the transfer zone in transform section was interpreted as convergent-overlap type based on the classification of Morley.The transfer zone between the two sections has transferred their displacements and keeps the conservation of fault displace-ments in Yudong 3 fault zone.The evolution of this transfer zone can be divided into three stages,i.e.the for-mation of isolated reverse fault,formation of transfer-zone and complication of transfer zone.
