Abstract

Abstract: A mathematical model of one dimension displacement was established in the base of taking into account the starting pressure gradient, and then a solution of equation was solved. The results indicated that in the lowermeability reservoirs, the presence of the starting pressure gradient cause to the increase of the formation pressure and the decrease of the average water saturation. Different direction of the oil displacement brought
the different effect in the low-permeability reservoirs development.

Key words: low-permeability, displacement, apparent viscosity, starting pressure gradient
