摘　　要：在介绍顶驱下套管驱动工具结构与原理的基础上,指出套管驱动工具的突出特点。介绍了国外顶驱下套管驱动工具的动力总成、限位总成和卡瓦总成的结构;阐述了动力总成中液缸径向和轴向2种抱紧套管的方式;分析了限位总成中减振限位、结构限位和送管控位3种限位方式。指出卡瓦总成中的球形卡瓦较传统卡瓦在承载能力上的优越性。指出了我国顶驱下套管驱动工具与国外的差距并提出发展建议。After introducing the structure and principle of casing drive tool, the casing drive tool＇s outstanding characteristics are pointed out. The tool includes several parts, such as power, limit assembly and slip assembly. In the power part, the hydraulic cylinder along radial and axial pro- moting the slips to hold the casing is described;in the limit assembly part,the paper introduce damping limit, the structural limit and casing feeder; in the slip assembly part, comparing with conventional slips,the advantage of ball slip is pointed out. Finally,our casing drive tool gap with foreign countries is pointed out and development proposals are put forward.
