浙江省天然气市场已进入高速发展阶段，“十二五”期间将逐步形成六大气源混输供应体系。气源多元化提高了天然气供应系统的安全性，但天然气产地及生产工艺不同，不同气源特别是管输天然气和液化天然气的组分及气质特性存在着较大差异，不同气源进入主干管网时必须考虑互换性。采用华白数法、美国燃气协会（A ．G ．A ）法对浙江省现有五大气源天然气的互换性进行了分析。借鉴国外解决多气源互换性问题的相关做法，提出了浙江省多气源混输格局下管网供气的解决方案。

The natural gas market has entered a stage of rapid development in Zhejiang prov-ince ,and six supply systems of gas source mixed transportation will be gradually formed during the twelfth five-year period .The diversification of gas source has improved the security of natural gas supply system and the interchangeability of different gas sources ,however ,must been taken into consideration when getting into the main pipeline network due to the differences of natural gas origin ,production process ,and gas source ,especially the air components and characteristics between natural gas and liquefied natural gas .Using Wobbe index method and America Gas As-sociation (A .G .A) method ,the interchangeability of five major sources of natural gas in Zhe-jiang province was analyzed .Referring to the foreign methods of solving gas interchangeability problem ,solutions of gas pipeline network supply under the structure of gas source mixed trans-portation in Zhejiang province are put forward .
