针对超深井短轻尾管悬挂及丢手判断难度大的问题,进行短轻尾管悬挂、丢手判断关键技术分析研究。以塔河油田超深井短轻尾管作业实践为基础,进行理论分析和经验总结,提出短轻尾管范畴,引入顶升力影响因素,形成了以“上提悬挂，下压丢手”为原则、理论计算实测跟踪为手段、多方面考虑多角度验证为保障等一系列技术方案。将超深井短轻尾管悬挂、丢手判断数据化、规范化。应用表明,该技术方案具有易操作、低风险的优点，可有效解决超深井短轻尾管悬挂及丢手判断难的问题，对超深、复杂地层的油气开发具有参考意义，值得进一步优化及推广应用。

In view of the judging difficulties in hanging and releasing short-light liner in ultra-deep well, analysis has been carried out on the key technique of hanging and releasing in short-light liner operation.Based on the practice of short-light liner cementing in the ultra-deep well of Tahe Oilfield, the theory analysis and experience summary were carried out, and the category of short-light liner was proposed, and the influencing factors of top-lift were introduced.In this paper, a series of technical solutions are formed such as the lift-hanging and press-releasing, theoretical calculation of measured tracking as a means, and multi-angle verification as a guarantee.The data of the short-light liner in ultra-deep well is analyzed and standardized.Field application shows that the method has the advantage of easy operation and low risk,which provides technical support for short-light liner work,and guidance for ultradeep,complex for mation of oil-gas development and is worth further optimization and application.
