摘　　要：杨村断裂是金湖凹陷南部边界断层,控制龙岗、汊涧次凹形成和演化,由于其展布方位与区域南北向拉张应力的交角不同,导致沿走向不同部位断裂性质、活动性等存在明显差异。正是基于这种差异,杨村断裂不同部位对油气运聚的控制作用也有所不同,为进一步总结杨村断裂油气运聚规律,挖掘该区成藏潜力,指导下步勘探方向,从断裂应力特征、活动性质、断面形态等多个角度对杨村断裂几何、运动学特征进行系统研究,结合现今已发现的油藏,总结杨村断裂对油气运聚的控制作用,建立断裂控藏主要模式,同时指出了杨村断裂下步勘探有利层系与潜力地区。Yangcun Fault,located in the south boundary of Jinhu Depression,controlled the formation and evolution of Longgang and Chajian sub -depression.Affected by NNE regional strike -slip stress,the stress characteristics of different parts along its trend varied,with a complicated fault system which has multiple tectonic patterns.The formation and evolu-tion features of Yangcun Fault were systematically studied in this paper from various aspects,such as fault stress character-istics,activities,tectonic patterns,and so on.Combined with the information of discovered oil reservoirs,analyzed the con-trol functions of faults on oil and gas migration,the main pattern of fault controlling to reservoir was established,which can guide the future prospection direction of the interested area.
