摘　　要：综述了水平井数值模拟研究的最新进展,内容包括:水平井砾石充填机理及技术难题、充填过程中平衡砂床高度、临界流速的计算模型,描述了筛管/井筒环空砂浆流动、冲管/筛管环空纯携砂液流动以及它们之间流体的交换和向地层的滤失过程.重点介绍了α波充填过程中流动数学模型的研究现状及影响水平井砾石充填的各个因素和存在的问题.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 α wave packing, factors affecting horizontal well gravel-pack efficiency and existing problems are also discussed.
