摘要
近年来,随着实体膨胀管技术的不断发展,国外成功研制了可膨胀尾管悬挂器并逐渐趋于成熟,在很多油气田投入工业性应用,取得了显著的经济效益。详细介绍了里德公司的HETS-LH悬挂器、TIW公司的XPAK悬挂器、哈里伯顿公司的VersaFlex悬挂器和威德福公司的EXR悬挂器的基本结构、工作原理及现场应用情况,分析了其优缺点,并在此基础上对国内可膨胀尾管悬挂器的研究与发展提出了建议。
In recent years, with the development of sohd tube expansion technology, the overseas ex pandable liner banger （ELH） technology is gradually becoming mature. The ELH has been applied in many oil and gas fields and remarkable benefits have been achieved. This paper introduces the structure, mechanism, on-situ application and performance of ELHs made by Read, TIW, Halliburton and Weatherford. In addition, recommendations for research and development of domestic ELHs are proposed.
