摘　　要：真武-汉留断裂带构造复杂,前人研究了两者演化特征,但未明确其演化的内在联系,针对此问题,基于三维地震解释资料,运用构造几何学运动学分析方法,利用断层活动性定量表征手段,剖析各断层几何特征和活动规律,总结形成演化模式,进而分析其对油气聚集成藏的影响。研究结果表明:断层走向转变与区域应力场变化有关;真①断层分段性影响了真②和汉留断裂带分段特征;分段形成的横向背斜有利于油气聚集成藏,控制油气在平面上呈带状分布。该研究为该区的勘探开发提供新的思路。Based on the 3D seismic interpretation,tectonic geometry kinematics analysis was used to further understanding the formation and evolution patterns of Zhenwu-Hanliu fault zone in Gaoyou sag.Quantitative characterization of fault activity was adopted to analyze the geometric features and activity patterns.The corresponding evolution mode was summarized to analyze its effect on hydrocarbon accumulation.Research indicates that the fault strike variation is dependent on the variation of regional stress field.The Zhen①fault segmentation affects the segmentation features of Zhen②and Hanliu fault zone.Segmented lateral anticline is favorable to hydrocarbon accumulation,which controls the zonal hydrocarbon distribution.This research could provide new ideas for the exploration and development in this area.
