摘要(Abstract)：

为研究断裂在油气成藏与分布中的作用,在松辽盆地升西—徐家围子向斜区葡萄花油层和杏北地区扶余油层断裂发育及分布特征研究的基础上,采用断裂输导、封闭与油气分布之间关系分析方法,研究升西—徐家围子向斜区葡萄花油层和杏北地区扶余油层断裂控藏作用的差异性.结果表明:由于油运移方式不同,2个地区断裂输导油和聚集油作用存在差异性,升西—徐家围子向斜区断裂对葡萄花油层油运移起垂向输导作用,杏北地区断裂对扶余油层油运移起侧向连接输导作用;升西—徐家围子向斜区葡萄花油层油主要聚集在油源断裂上盘,即断裂密集带内,杏北地区扶余油层油主要聚集在反向断裂的下盘,即断裂密集带两侧,且反向断裂断距越大,越有利于油聚集.该研究结果对认识松辽盆地凹陷区下生上储式和源外隆起区上生下储式油气成藏规律和指导油气勘探具有参考意义.
