摘要
The internal structure of fault zone in extensional normal fault consists of fault core and damage zone.There may be several slip surfaces and kinds of fault rock in fault core which the permeability of them depends on both the shale content in the fault zone and the type of fault rock. Based on the relationship between the SGR value of sealing fault in fault zone and the pressure difference between footwall and hanging wall, the quantitative relationship is established between SGR value and height of hydrocarbon column sealed by lateral fault seal. Fault trap can be classified as entirety efficient trap, partly efficient trap and entirety inefficient trap according to the height of hydrocarbon column and its scope.
