【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。更多还原

【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.更多还原
