| Abstract: | Basing oil the analysis of the sand stress,this paper discusses the effect of gravity, Van der Waals force and repelling force of double electrical layer on sand production,and presents the concept of threshold flow velocity of reservoir sand production. It is of practical significance to rational determination of oil well productivity and reservoir protection. |

| Keywords: | reservoir sand production sand stress threshold flow velocity oil well productivity |
