In order to evaluate the controlling effect of sandstone heterogeneity on oil-bearing difference in sandstone carrier bed, from the point of view of hydrocarbon accumulation dynamics, using the empirical relationship between porosity, permeability and displacement pressure, the displacement pressure of different sand bodies of the sandstone carrier bed in reservoir conditions is calculated. By comparing with the oil-water interpretation, the upper limit of reservoir displacement pressure in the north of Nanpu 4 structure is finally determined.
