Gas well high-pressure pipeline friction resistance coefficient measurement and vibration monitoring device and method

The invention belongs to the field of onshore natural gas development, and particularly relates to a gas well high-pressure pipeline friction resistance coefficient measuring and vibration monitoring device and method. And gas pipe friction resistance and vibration signals generated when different gases pass through the simulation pipeline at a high speed can be simulated. According to the gas well high-pressure pipeline friction resistance coefficient measuring method, the actual production process is directly simulated, the gas friction resistance is directly calculated through the gas parameters and the pipeline parameters, and data are more real. According to the gas well high-pressure pipeline vibration monitoring method, the change rule of the whole displacement of the simulation pipeline along with the gas injection time is analyzed according to the displacement attenuation characteristics of all the measuring points at the same time, due to the fact that gas friction and pipeline vibration are correla
