| 摘 要： | 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。

| Abstract: | 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 displacement-distance method. The Yubei area mainly consists of a number of faults striking northwest. From the northeast section to the southwest section, the direction of the main fault gradually changed from southeast to northwest. 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 displacements in Yudong 3 fault zone. The evolution of this transfer zone can be divided into three stages, i.e. the formation of isolated reverse fault, formation of transfer-zone and complication of transfer zone. |
