摘要(Abstract)：

为了分析断裂在方正断陷油气成藏与分布中的作用,在断裂发育及系统划分基础上,采用断裂系统与油气分布之间叠合分析方法,研究方正断陷断裂系统对油气成藏与分布控制作用及模式.结果表明:方正断陷断裂系统对油气成藏与分布控制作用主要表现为:(1)Ⅵ类断裂系统为东部油气运移提供输导通道,其下盘断鼻构造是油气聚集的有利部位.(2)反向Ⅰ、Ⅳ类断裂系统为西部油气聚集提供遮挡条件,并且其封闭能力控制油气聚集.断裂系统控藏模式包括:(1)Ⅵ类断裂输导下盘在断鼻构造中控藏模式;(2)反向Ⅰ、Ⅳ类断裂下盘遮挡圈闭控藏模式.研究结果对认识方正断陷油气成藏与分布规律,指导该地区油气勘探有参考意义.

关键词(KeyWords)：方正断陷;断裂系统;油气运移;油气聚集;控藏模式
