中文摘要：

探讨乌尔逊凹陷的构造特征及其演化规律，采用地震解释方法对构造层序界面进行识别与划分。结果表明乌尔逊凹陷发育四个区域性构造层序界面，将盖层划分出四个构造层。得出鸟尔逊凹陷经历了4个形成期和3个改造期的构造演化阶段。

英文摘要：

We probed into tectonic characteristics and evolution law of Wuerxun sag,integrated with seismic interpretation on identification and division of tectonic sequences interface.The results showed that Wuerxun sag had developed four regional tectonic sequences interface, and four tectonic layers out from cap rock.We concluded that Wuerxun sag had experienced four forming periods and three transforming periods of tectono-evolutionary stages.
