中文摘要：

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一百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。

英文摘要：

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 strlke-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.
