摘　　要：提出了将卡钻类型分为机械卡钻、压兰卡钻和循环卡钻三类的新方法。利用华北油田卡钻事故资料，通过多元聚类分析和多元判别分析的方法，建立了三类卡钻事故的预测模型，预测结果符合生产实际，可以作为卡钻事故处理的依据。A new classification for stuck pipe is presented in which the stuck pipe can be divided into mechanical, differential and circulation sticking. The prediction model is established by multivariate cluster and diagosis analysis, based on the stuck pipe data of Huabei Oilfield. The prediction results conform to the reality. The model can be used as a guideline for dealing with the drilling problems of stuck pipe.
