【摘要】 准噶尔盆地西北缘中拐地区发育逆冲断裂带,同时还发育一系列花状构造。在区域构造特征分析基础上,以高分辨率三维地震资料为依据,对中拐地区断裂体系进行了研究。结果表明:该地区花状构造对油气的运聚成藏具有重要的双重控制作用,它既能作为有效的运移通道,又能够起遮挡作用而形成圈闭。这一认识对中拐地区及其他与其构造相似地区的油气勘探开发具有一定的参考价值。图3参8更多还原

【Abstract】 Thrust belts are developed in Zhongguai area,northwestern margin of Junggar Basin,and a series of flower structures are simultaneously developed. Based on regional structural characteristics analysis,the fracture system in Zhongguai area is studied according to high-resolution 3D seismic data. The result shows that the flower structure,which can not only act as an effective migration pathway but also a barrier resulting in forming trap,has a significant control on both migration and accumulation. This understanding guides E&P in Zhongguai area and other areas with similar structure.更多还原
