摘　　要：本文介绍了管柱伸缩器的结构、工作原理、应用工艺及其在吐哈油田现场试验情况。管柱伸缩器应用于分层注水、气举采油等完井管柱中,可有效补偿因压力、温度等因素的变化而产生的额外管柱伸缩量,避免因管柱蠕动引起封隔器的失效或降低封隔器的使用寿命,从而延长动管柱周期,达到节约作业费用的目的,同时也阐述了这种管柱伸缩器存在的不足及下步改进措施。This paper introduces the structure,working tenet and applied technology of pipe string expansion system.It was used in zonal injection and pipestring of gas lift completion to compensate expansion length of extra pipe string caused by the change of pressure and temperature and also avoid to lose efficacy of packer or decrease packers' life caused by wriggle of pipe string.So the string expansion system can extend period of pipe string to save the work cost.
