Abstract

Abstract: The cyclic water flooding in layered heterogeneous sandstone reservoir has been studied by means of VIP simulator and pseudo-2 -layer geologic model in order that the cyclic water flooding method would be tested and widely used in field. By studying the influence of various geologic development and factors on cyclic water flooding results in layered heterogeneous sandstone reservoir, the mechanism of cyclic water flooding in layered! heterogeneous sandstone reservoir has been derived; the interlayer pressure difference and elastic force are strengthened, capillary pressure and gravity are activated, flow passing alternately through low permeability and high permeability layers are caused in cyclic water flooding, and finally the reservoir volume and ultimate recovery factor by water flooding are improved.

Key words: Sandstone reservoir, Cyclic injection, Heterogeneity, Numerical simulation
