掺氢天然气管道输送能够高效解决氢气产地和用氢地域的错配问题。然而，氢气注入天然气后，改变了原管道系统输送气体的流动状态及热力学特性。因此，对管道输送掺氢天然气的管线压缩机、计量方面的影响进行了总结；然后，综述了近年来对各种工况的掺氢天然气热物理参数研究内容，包括密度、温度、压力、黏度、比热容、互换性、压缩因子、发热量及焦耳-汤姆逊系数；最后，展望了掺氢天然气热物理参数研究的发展趋势。掺氢天然气热物理参数的总结能够为后续掺氢天然气管道输送的理论研究和工程应用提供参考。

The problem of mismatch between hydrogen production area and use area can be solved with hydrogen-injected into natural gas pipeline transportation effectively. However, the flow state and thermodynamic characteristics have been changed in the original pipeline system after hydrogen-blended into natural gas. Therefore, the influence of hydrogen-blended into natural gas of compressor and metering was summarized in pipeline transportation system. Then, thermophysical parameters of hydrogen-blended into natural gas was reviewed, including density, temperature, pressure, viscosity, specific heat capacity, interchangeability, compression factor, calorific value and Joule-Thomson coefficient, et al. Finally, the development trend of research on thermodynamic property parameters of hydrogen-blended natural gas were prospected. The summary of thermodynamic parameters can provide references for the theoretical research and engineering application of hydrogen-blended natural gas pipeline transportation.
