及早识别卡钻迹象并采取适当措施，可以大幅减少钻井过程中的非生产时间，并提高钻井安全性。本文提出了一种时间序列分析方法，并描述了一种可靠、易用的工具，用于自动、准确、早期地检测卡钻。基于深入的理论分析和历史卡钻数据分析，本文主要识别了钻井作业中出现的早期卡钻指标。
一般来说，卡管事故可分为差动卡管事故和机械卡管事故。本文详细介绍了差动卡管事故的机理和症状，以及机械卡管事故的主要类型。
卡管迹象。虽然卡管的原因各不相同，但地面测量数据反映出的不同类型卡管的迹象非常相似。
Recognizing stuck-pipe signs early and adopting appropriate action can greatly reduce nonproductive time during drilling and improve drilling safety. This paper proposes a time-series-analysis approach and describes a reliable, easy-to-use tool to automatically detect stuck pipe accurately and early. Based on an in-depth theoretical analysis and historical stuck-pipe-data analysis, primarily early stuck-pipe indicators seen in drilling operations are identified.
In general, stuck-pipe incidents can be classified as differential and mechanical. The mechanisms and symptoms of differential sticking and the primary types of mechanical sticking are detailed in the complete paper.
Stuck-Pipe Indicators. Although the causes of stuck pipe vary, the signs of different stuck-pipe types reflected in surface measured data are very similar.
