深部找矿钻探工程施工中的风险评价

Risk assessment in the construction of deep prospecting and drilling engineering

深部找矿需要较深的深孔钻进,而在实际操作过程中时常会遭遇诸多的施工难题。针对深部找矿钻探工程施工中基础信息参数存在不确定性等一系列问题,以数学分析方法为基础,通过分析钻探工程中井下风险发生的致险机理,构建深部找矿钻探工程施工中的风险评价方法。本文提出的深部找矿钻探工程施工中的风险评价方法在对井下故障发生几率上的判别上具有明显优势,具体表现为其对风险的评价正确率远高于传统方法。

Deep exploration requires deep hole drilling,and in the actual operation process,there are often many construction problems.In view of a series of problems such as the uncertainty of basic information parameters in the construction of deep exploration and drilling engineering,based on the mathematical analysis method,the risk assessment method in the construction of deep exploration and drilling engineering is constructed by analyzing the risk causing mechanism of underground risks in the drilling engineering.The risk assessment method proposed in this paper has obvious advantages in distinguishing the probability of downhole failure,which is shown in that the accuracy of risk assessment is far higher than the traditional method.which is shown in that the accuracy of risk assessment is far higher than the traditional method.
