摘　　要：为了保证特高压井口的远程控制、信号传输和通讯功能在役全过程良好实现并风险可控,本文采用“风险辨识—事件树分析—不确定性分析”3步结合的风险分析方法,辨识井口远程终端控制系统涉及风险源,确定各失效模式发生频率,针对评估结果中重要危险场景进行不确定性分析,判断其失效概率的波动情况。研究结果表明:特高压井口远程终端控制系统中控功能风险在可接受范围内,本文使用的风险分析方法能直观定量识别出系统内重要风险点,并给出相应建议。To ensure that the remote control,signal transmission and communication functions of the ultra⁃high⁃pressure(UHP)wellhead are well realized and the risks are controllable,this paper adopts a analysis method combining“Risk identification-ETA-Uncertainty analysis”to identify the risk sources related to the UHP wellhead remote terminal unit(RTU)control system,determine the frequency of each failure mode,and analyze the uncertainty of the important danger scenarios in the assessment results to judge the fluctuation of its failure probability.The results show that the risk of the central control function of the UHP wellhead RTU control system is within the acceptable range,and the risk analysis method used in this paper can intuitively and quantitatively identify the important risk points in the system and give corresponding suggestions.
