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.
