HAZOP技术是一种用于辨识装置设计缺陷、工艺过程危害及可操作性问题的定性风险评价方法，主要通过偏差查找事故发生的原因、可能造成的后果，并且在已有保护措施的基础上，提出控制或降低风险的建议措施。因其分析的系统性、科学性等优点，目前已广泛应用于石油、化工等行业。针对地下储气井腐蚀、老化等问题的日益凸显，采用 HAZOP技术对CNG 地下储气井展开安全性分析，共提出了建议措施94条，采用率达到90％以上，为生产安全管理工作提供了有力依据。同时，归纳总结了HAZOP技术的优缺点，明确了今后改进的方向。%HAZOP technology is a qualitative risk assessment method used to identify the design defects ,process hazard and operability problems .It mainly finds the consequences and the cause of the accident through deviations ,and on the basis of existing protective measures ,it proposes the sug‐gestions to control or reduce risk measures .Because of its advantages of systematic and scientific , HAZOP has been widely used in petroleum ,chemical industry ,etc .In view of the underground gas storage well growing problems such as corrosion ,aging ,this article used the HAZOP technology to analyze CNG underground gas storage well safety for the first time .The article proposed 94 measures and the adoption rate could reach more than 90% ,w hich provided a strong basis for the production safety management .Meanwhile ,the advantages and disadvantages of HAZOP technology were sum‐marized ,and the direction of future improvement was clear‐cut .
