Abstract:

An evaluation to the saturation of oil & gas pool in accordance with the characters of reservoir &seal from the view of combining reservoir with seal is presented in the paper. The study suggests that reserving capacity is determined by the reservoir characters and the trapper characters the latter influences the petroleum migration. Furthermore, the strength and orientation of hydraulic flow may increase or decrease the height of oil & gas pool. It is indicated errors may be introduced because of the shortage of trapper’s data.
