文摘

Multiple pressure systems is consisted of three overpressure units. Three overpressure units corresponds to Es1, Es3 and Es4 source rock intervals. Most of hydrocarbons accumulated in the middle and bottom overpressure units. The migration of faults for hydrocarbon sourced from Es3 interval is more significant than that from Es4 interval. The pressure structure, the pressure seal ability and the overpressure evolution are all found to contribute to the distribution of hydrocarbons.
