摘要： 准噶尔盆地西北缘前陆冲断带构造样式复杂多样，除规模较大的逆断层外，还发育一系列北西向的走滑断层。以高分辨率三维地震资料为基础，对断裂体系分析表明克拉玛依—百口泉地区的走滑断层可分为花状走滑断层和简单走滑断层两类，二者在成因、剖面特征等方面具有明显差别。研究结果认为走滑断层对油气的运聚成藏具有重要的双重控制作用，即能作为有效的运移通道，又能够起遮挡作用而形成圈闭。

Abstract: The foreland thrust belt has complex and various structural styles. Besides the large-scale reverse faults, there are a series of north-west strike-slip faults. Based on high-resolution seismic data, the foreland fault systems in the NW margin of Junggar basin were analyzed. It reveals that the strike-slip fault system of Ke-Bai area can be divided into two types, namely the flower strike-slip faults and the simple strike-slip faults, which have obvious differences in genesis and section features.The strike-slip faults have dual influence on hydrocarbon migration and accumulation. They can not only be effective migration channels for petroleum, but also can seal petroleum.
