Expanding Screen Sand Control——A New Way for Mechanical Sand Control

摘要: 文章详细地介绍了膨胀筛管的基本结构、防砂机理及该项技术的优缺点。在辽河油田室内实验及现场应用试验的成功,为今后既防砂又能提高套管机械强度的防砂技术迈出了先导性的一步。

Abstract: It was described roundly the structure of the expanding screen the mechanisms of sand control and the advantages and disadvantages of using this technology in the paper. The technology,both sand control and enhancing the casing mechanical strength,has succeeded with experiment in laboratory and locales,which has stepped a prescient pace for the future.
