摘要

在超高压管网进行水力计算时，必须考虑天然气的压缩系数。讨论了天然气压缩系数的几种计算方法及特点。通过拟合S-K模态图和状态方程，分别计算超高压多气源网络中天然气的压缩系数，然后根据各气源供气量加权平均。结果表明，超高压多气源管网水力计算中，合理选择天然气压缩系数计算方法至关重要。

Study of Compression Factor of Natural Gas in Superhigh Pressure and Multiple Source Networks

Compression factor of natural gas must betaking account of when doing hydraulic calculations in super high pressure network. Several calculation methods and features of compression factor of natural gas were discussed. The compression factor of natural gas in a super high pressure and multiple source network was calculated separately by fitting S-K nomogram and state equations, then weighted average according to the quantity of gas supply of each source. Results indicate that hydraulic calculation of super high pressure and multiple source network, chosing calculation methods of compression factor of natural gas resonably is critical.
