中缅天然气管道放空实践及思考

天然气放空对气源和用户均会造成显著影响,同时在工程实践中存在较大安全风险,因此放空是输气管道维修施工及应急处置中的重要环节之一。基于天然气管道实际情况及相关标准规范的要求,采用科学工具确定放空关键参数是确保放空安全经济性的关键。通过对中缅天然气管道进行深入分析,确定其放空初始压力、选择可行的放空方式、计算放空时间、评估其对环境的影响;并对中缅干线管道放空实践等进行论述,为合理组织输气管道维修施工、提高输气生产调度决策水平提供了实践依据与技术支持。

Practice and thought on venting of China-Myanmar Natural Gas Pipeline

Natural gas venting will have a significant impact on the gas sources and users,and great safety risks may exist in engineering practice.Therefore,gas venting is one of the important tasks in the maintenance and construction of the gas pipeline.Determining the key parameters of venting with scientific tools based on the actual conditions of gas pipelines and requirements of the related standards and codes is critical to ensure the safety and economy of venting.Definitely,the initial pressure of venting was determined,a feasible venting method was selected,the venting time was calculated and its impact on the environment was evaluated through in-depth analysis of the China Myanmar Natural Gas Pipeline.Additionally,the practice of venting the China Myanmar main pipeline was discussed to provide important practical basis and technical support for reasonably organizing the maintenance and construction of gas pipelines and improving the decision-making level of gas production scheduling.
