摘要/Abstract

摘要： 本文从砂粒的受力分析出发，讨论了重力、范氏力和双电层斥力对出砂的影响。提出了油层出砂的门限流速概念，对于合理地确定油井产能、保护油层有着一定的实际意义。

关键词: 油层出砂, 砂粒受力, 门限流速, 油井产能

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.

Key words: reservoir sand production, sand stress, threshold flow velocity, oil well productivity
