摘要
以套管失效为顶事件建立了石油套管的故障树。通过对故障树的定性分析 ,得到了最小割集 ,确立了套管的主要失效形式为潜在损坏、套管挤毁、套管断裂及严重腐蚀 。
Taken the casing failure as top event, the fault tree was established in the paper. By qualitative analysis, the minimum cut sets were obtained. The casing failure is latent damage, collapse, fracture and serious corrosion, finally the paper presents some measures of improving reliability of the casing.
