摘　　要：在伸展盆地中,构造转换带对油气具有重要的控制作用,往往是油气聚集的有利部位;在简化构造转换带概念基础上,分不同构造层对研究区构造转换带进行系统识别、特征分析及形成机制研究;综合钻井、地震及油藏资料,总结了高邮凹陷构造转换带对油气成藏控制作用。研究认为高邮凹陷构造转换带主要发育形式为走向斜坡、横向低凸起及变换断层,对沉积砂体展布、圈闭及油气运移聚集具有明显的控制作用,是下步勘探的有利目标。In the extensional rifted basin ,the structure transfer zone has a significant control on petroleum ,which is u-sually a favorable position for petroleum accumulation .On the basis of simplifying the concept of the structure transfer zone ,it was carried out a series of studies on system recognition ,characteristics analyses and formation mechanism accord-ing to various structural layers in the research area .By integrating drilling,seismic,and reservoir data,it was summarized the controlling effect of the structure transfer zone on petroleum formation in Gaoyou sag .The research results suggested that the main types of the structure transfer zones are relay ramp ,transverse relief and transform fault ,which obviously af-fect on the sand body distribution ,trap and petroleum accumulation ,and are favorable exploration targets in the future .
