摘要
简要分析了压差卡钻的机理，提出了影响压差卡钻临界值ΔＰＬ的几个因素。指出临界值是一个受多因素影响的变量而非固定值，并利用多元回归分析方法和中原油田实际卡钻井的数据资料，给出临界值计算模式，结果可用于指导生产实际。
The mechanism of differential sticking isbriefly analyzed, and some factors effecting criticalvalue of differential sticking are pointed out. The value is a variable, not a fixed value effected by variousfactors. With multivariate regression analysis and thedata from actural sticking wells in Zhongyuan Oilfield,the calculation model for critical value are presented,which can be applied in practices.
