By using Gaoyou Depression in Subei Basin as an example, the constrains of discordogenic faults to deposit , structure and potential field of fluid are analyzed. It is considered that the discordogenic faults not only control the factors of source, reserve and cap-rock, also control the factors of migration and accumulation. Effect of the big boundary fault in Gaoyou Depression on oil & gas migration and accumulation is emphatically analyzed. It is pointed out that the discordogenic faults not only control the reservoir plane distribution characters of the oil and gas bearing basin, but also control the vertical distribution of hydrocarbon properties.
