油气管道并行敷设技术研究现状

我国油气管道并行敷设技术的应用和研究逐渐增多,简要介绍了我国数个大型油气管道并行敷设工程情况,对其安全性问题进行了探讨。总结了近几年来一些学者从不同角度进行研究所得的成果以及新技术、新方法在工程实践中的具体应用。分析了在管道间距的确定原则、管间热力影响和管道施工技术研究中存在的问题与不足,展望了油气管道并行敷设技术的研究方向和发展趋势。对油气管道并行敷设中的各种影响因素进行综合考虑,多条油气管道并行敷设及其合理布局、站场优化,均有待于进一步研究。

Research Status in Parallel Laying Technology of Oil and Gas Pipelines

The application and research on parallel laying technology of internal oil and gas pipelines are increasing.The problem of security and economy was discussed.Several large domestic projects were introduced.The results of some scholars＇ research from different angles and the specific applications of new technology and methods in engineering practice in recent years were summarized.The problems and insufficiencies existing in the research of the determining principle of pipeline spacing,thermal effect between pipelines and pipeline construction technology were analyzed.The research direction and the development trend of the parallel laying technology were looked into the distance.Comprehensively considering influence factors in parallel laying oil and gas pipelines,rationally laying and distributing several parallel oil and gas pipelines,and station optimization,have to be for further research.
