摘　　要：徐家围子断陷具有良好的天然气勘探前景。为了搞清徐家围子断陷构造及其演化特征,采用断层相关褶皱的原理和几何分析方法,利用平衡剖面的模拟技术,对徐家围子断陷断层相关褶皱类型及演化模式进行了探讨。研究认为:徐家围子断陷建造期发育正断层相关褶皱,改造期发育断层转折褶皱,正断层相关褶皱具有控盆和控隆作用,控制了徐中隆起、徐西坳陷和徐东坳陷的形成和发育,断层转折褶皱具有控制构造带和局部构造的作用,是有利的油气聚集区。Xujiaweizi Fault Depression has good gas exploration prospect. In order to make sense of the structures and their evolutionary characteristics, with the help of fault-related fold principle, geometric analyzing method and balanced section simulating technique, the types and evolutionary models of the fault-related folds in the depression are explored and discussed. The studies show that the normal-fault-related folds were developed in the building pe- riod of the depression, the fault-bending folds were developed in the reconstructed period; the former possesses the controlling actions on the basin and uplifts i. e. controls the formation and development of Xuzhong Uplift, Xuxi and Xudong Depressions; the latter dominates the structural belts and partly structures, is the favorable oil and gas accumulation areas.
