  • The paper discussed the geological forming cause of reservoirs which distribute like brushes, brought forward the limitation of fault-sealing, and validated it by physical simulation experiment. Through the comparison between measured data and calculated data of oil column height sealed by fault, it is believed that the fault-sealing for oil and gas is limited. When hydrocarbon column height reaches the threshold, oil will spill from the top of reservoir along fault, and the scale of reservoir will remain invariable. When the sealing capacity of fault is settled, the area of oil and gas in fault-screened traps is controlled by the obliquity of reservoirs. The area of oil and gas increases with the decrease of reservoirs obliquity.
