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 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.
Key words: Yubei area; Yudong 3 fault zone; segmentation; transfer zone; evolution characteristic
