摘　　要：本文运用故障树分析法,建立钻井井塌事故的事故树模型,通过计算最小割集、最小径集、结构重要度进行定性分析。通过对井塌事故定性分析可知,有192条路径会导致钻井井塌事故的发生,有12种方案可预防钻井井塌事故的发生。找出了对顶上事件发生影响最大的事件,为钻井井塌风险的预防以及安全管理工作提供了可靠的依据。Using the fault tree analysis method,an accident tree model of drilling well collapse accident is established,and the qualitative analysis is carried out by calculating the minimum cut set,minimum diameter set,and structural importance.Through qualitative analysis of well collapse accidents,it can be known that there are 192 paths leading to drilling well collapse accidents,and there are 12 schemes to prevent drilling well collapse accidents.The events that have the greatest impact on the top-of-line events is identified,and a reliable basis for the prevention of drilling well collapse and safety management is provided.
