摘　　要：分析了埋地天然气管道的水力特性、热力特性,介绍了利用BWRS方程求解天然气物性参数的方法。利用MATLAB App Designer模块开发埋地天然气管道物性参数分析软件(简称本软件),功能包括天然气物性参数计算、沿管长方向压力和温度计算。利用本软件对低压、中压、次高压3个天然气管道示例进行计算,得到了沿管长方向的天然气压力、温度及物性参数。为验证本软件的准确性,利用Pipeline Studio软件进行稳态模拟,将本软件计算结果与Pipeline Studio软件稳态模拟结果进行对比。本软件计算结果与Pipeline Studio软件稳态模拟结果基本吻合,本软件具有较高的准确性。The hydraulic and thermal characteristics of buried natural gas pipelines are analyzed,and the method of solving gas physical parameters by using BWRS equations is introduced.A software for analyzing the physical parameters of buried gas pipelines is developed by using MATLAB App Designer module(referred to as this software),which includes the calculation of natural gas physical parameters and the calculation of pressure and temperature along the length of the pipeline.This software calculates three gas pipeline examples of low pressure,medium pressure and sub-high pressure,and the gas pressure,temperature,and physical parameters along the length of the pipeline are obtained.To verify the accuracy of this software,Pipeline Studio software is used for steady-state simulation,and the calculated results of this software are compared with the steady-state simulation results of Pipeline Studio software.The calculation results of this software are basically consistent with the steady-state simulation results of Pipeline Studio software,and this software has high accuracy.
