摘　　要：依据前人对构造变换带的研究,其可分为变换带和调节带2种,二者在应力机制、构造样式、发育部位等方面具有明显的差别。本次研究针对乌尔逊凹陷的铜钵庙构造带、巴彦塔拉构造带、苏仁诺尔构造带这3个较大的变换构造带,并运用其基本理论,结合地震解释资料,分析乌尔逊凹陷构造特征,认为铜钵庙构造带与巴彦塔拉构造带、苏仁诺尔构造带在剖面特征、平面断裂特征和剖面演化等方面存在明显差异。结果表明:铜钵庙构造带为构造调节带,巴彦塔拉构造带和苏仁诺尔构造带为构造变换带。Based on the previous studies, structural transfer zones can be divided into two types： transfer zone and accommodation zone, between which there are significant differences in the aspects of stress mechanism, structural pattern and development position. This study focuses on three large structural transfer zones of Wuerxun Depression： Tongbomiao structural belt, Bayantala structural belt and Surennuoer structural belt. The basic theory of structural transfer zone combined with seismic data is applied to analyze the structural characteristics of Wuerxun Depression. The result shows that there are obvious differences among Tongbomiao structural belt, Bayantala structural belt and Surennuoer structural belt in the aspects of structural characteristics, plane fracture characteristics and profile evolution. And it is believed that Tongbomiao structural belt is accommodation zone, while Surennuoer structural belt and Bayantala structural belt are transfer zones.
