摘　　要：膨胀筛管防砂技术是最近几年内出现的一种新型完井工艺,即在套管的射孔段或裸眼的目的层段下入膨胀筛管,然后膨胀在井壁或套管内壁用来防砂。详细介绍了膨胀筛管管串的组成、筛管的结构原理、筛管的膨胀工具的结构和膨胀原理、筛管防砂机理等,在介绍膨胀筛管防砂技术在渤海湾油田的现场使用情况的基础上,对该技术的现场应用进行了风险分析。The expandable sand screen is a new type of completion technology in last few years. The first to be done is running this tool in perforated hole sections or target intervals of open holes, and then expanding it against casings or wellbores for sand control. This article details its components, design, structures and expansion principles of its expandable parts, sand control mechanisms, etc. This article presents field applications of this technology in Bohai oilfield as well as risk evaluations. 
