摘　　要：在松辽盆地杏北地区扶余油层油分布规律和断裂发育及活动特征研究的基础上，采用典型油藏解剖及油分布与断裂之间空间匹配关系分析的方法，对杏北地区断裂在扶余油层油运聚成藏中所起的作用进行了研究。结果表明：断裂对扶余油层油运移的控制作用主要有2个方面，一是断裂侧向输导是油向杏北中央背斜带北部运移的主要输导通道，二是断裂垂向输导造成油聚集分布层位变浅；断裂对扶余油层油聚集的控制作用也主要有2个方面，一是断裂密集带附近的正向构造是油聚集的有利部位，二是反向断裂规模控制着油的富集程度。On the bases on the studies on the oil distribution laws, fault development and its activity characteristics for Fuyu oil reservoirs in Xingbei region of Songliao Basin, the studies on the actions of the faults on the oil migration and accumulation are conducted with the help of the analyzing methods of the anatomy of the typical oil reservoirs and matching relation between the oil distribution and faults. The results show that the controlling roles of the faults on the oil migration are presented as follows： one is the lateral transportation of the faults is the main transporting pathways of the oil migrating to North Central Anticline Belt in Xingbei region; the rest is the vertical transportation of the faults results in the shallow accumulation of the oil ; the controlling actions of the faults on the oil accumulation show as follows： the first is positive structures near the fault condensed belts are favorable places for oil to accumulate; the second is the size of the transoid faults controls the enriched and accumulated degree of the oil.
