This paper reviews the latest
advances of numerical simulation for gravel packing in horizontal wells.
The discussions focus on the following topics: gravel packing process
mechanism and technology; calculation model for equilibrium bank
height and critical velocity in packing. A description is made on slurry flow in
screen/wellbore annuli, carried fluid flow in wash-pipe/screen annuli and
fluid transfer between two flow system and fluid leak-off into formation.
The mathematical model for bank height in $\alpha $ wave
packing, factors affecting horizontal well gravel-pack
efficiency and existing problems are also discussed.
