摘　　要：由于深水水下井口系统及井身结构设计套管层次多的特点,尾管悬挂工艺和尾管回接工艺是深水井的一项重要工艺技术。对目前国内外深水使用的常规尾管回接工艺技术进行了分析的基础上,详细阐述了其整个的工艺过程、相应工具的工作原理和特点以及现场应用情况,提出了存在的常见问题,并针对存在的问题结合目前常用的尾管回接工艺技术、使用情况以及国外行业的发展情况,介绍了2种不同思路的深水尾管回接工艺技术的发展方向,对后续深水尾管回接作业具有重要的借鉴意义。Due to the characteristics of wellhead system in deepwater,liner hanging and tieback technologies are important in deepwater wells. The paper introduces the conventional liner tieback technology in deepwater both in China and abroad,elaborates in detail about the whole process,working principles and characteristics of the corresponding tools and the field application; puts forward the existing problems. Aiming at the existing problems and according to the common-used liner tieback technologies and the application situation as well as the development conditions in foreign countries,the development direction of two liner tieback technologies,being developed with different ideas,for deepwater drilling are presented.
