摘　　要：塔里木盆地阿满地区走滑活动明显,发育了顺北1号、顺北5号等NE向大型走滑断裂带,这些断裂带存在明显的差异性,表现出“南强北弱”的特征.通过对顺北1号断裂不同位置及次级断裂的特征及活动性进行解析,并结合大量单井生产资料及地震资料分析了断裂对油气富集的控制作用.研究结果表明,顺北1号断裂不同位置及次级断裂在几何学、运动学及活动性上存在着很大的差异性.顺北1号断裂的差异性,使该断裂具有明显的分段性,形成了不同的走滑构造,这些构造控制了不同类型圈闭的形成和油气运移和聚集,进而影响着油气富集规律。Strike-slip fault activities are common in Aman area,Tarim Basin. There are many major strike-slip fault zones,including Shunbei 1 fault,Shunbei 5 fault and so on. The characteristics of these faults are obviously different,generally strong in the south and weak in the north. Based on the analysis of the characteristics and activity of different locations and secondary faults of Shunbei 1 fault,and combined with a large number of single well production data and seismic data,we analyze the control of faults on hydrocarbon accumulation. The results show that there are great differences in geometry,kinematics and activity between different locations and secondary faults of Shunbei1 fault. We find the difference of Shunbei 1 fault makes the fault has the distinct segmentation and forms of different strike-slip structures which controls the formation of different types of traps,migration and accumulation of oil and gas,and then it affects the regularity of oil and gas accumulation.
