石油天然气钻井工程风险量化技术

基于风险的概念,在对石油天然气钻井工程设计、工艺设备、施工管理、复杂情况和事故等总体分析的基础上,提出钻井工程风险量化方法———风险评估指数系统。此方法结合科学计算和专家经验,确定了固有风险指标、事故易发性指标和后果严重度指标等三个指标及量化标准,并将钻井工程风险划分为4个等级,最终建立了由指数体系、评分体系、风险分级标准组成的风险评估系统。本方法可用于专业机构的风险评估,也可用于安全管理部门的检查,以指导采取相应措施降低工程的危险性。

Risk quantitative technology of oil and gas drilling engineering

Based on the concept of risk, a quantitative approach of risk in drilling engineering-risk, assessment in- dex system, was presented by analyzing the design of the oil and gas drilling engineering, equipment, construction management, complex situation and accidents. Combining with scientific computing and expertise, this approach determined quantitative criteria and three indicators-inherent risk indicators, accident-prone indicators and conse- quences severity index, and it divided drilling was established which was made up of index engineering risk into 4 levels, eventually the risk assessment system system, scoring system, and risk classification standard. This ap- proach can be used for risk assessment of the professional institutions and also for the inspection of the safety man- agement departments to take appropriate measures to reduce the risk of the project.
