摘　　要：高邮凹陷横向变换构造带具有不连续的"S"形展布特征。利用地震、地质等资料研究高邮凹陷主要断裂沿走向构造特征的变化,圈定了具有分区意义的横向变换构造带,分析不同构造部位发育的横向变换构造样式及其特征。同时,横向变换构造带不仅控制有机质的形成环境,而且自身也可以形成各种圈闭,成为不同次凹油气混注的油气富集区带。The transverse transition zones in Gaoyou Sag were distributed discontinuously in 'S' shape.Seismic and geological data were used to study the structural characteristics of main faults changes along their strikes in Gaoyou Sag.The transverse transition zones used as marks of zone partition were located.Types and characteristics of transverse transition structures at different structural positions were also analyzed.Transverse transition zones can not only dominate the forming environment of the organic matter,but also can form various traps by themselves,it becomes the area of abundant oil and gas enrichment in different sub-depressions.
