摘　　要：城市燃气用气有季节、月、日及小时的不均衡性,根据国内某城市的预测数据分析,随着该城市用气量的增加,其所需调峰量也逐渐增加,但调峰缺口率却越来越大。为了解决这种供气与用气之间的矛盾,介绍了5种城市储气调峰的方式及其特点,包括水合物形式储气(NGH)、地下储气库储气、储气罐储气、高压管道储气和液化天然气储气。然后结合具体城市,对5种储气方式经过技术经济等比较后,最终得出了高压管道储气是该市最经济的储气调峰方式的结论。The urban use of natural gas has a non-balanced characteristic of season, month, day and hour. According to the analysis of some predicted urban data concerning a city, with an upgrading of urban gasification, its peak modulation volume needs to be increased gradually. However,the lack rate of peak shaving is also growing, so, in order to solve the contradiction between supply and demand,this paper introduces the characteristics of five kinds of urban peak modulation of gas pipeline, inculding NGH, underground gas storage, storage, high-pressure pipeline and LNG. Then,in combination with the concreted condition of the city,it also compares the scheme for packing the gas pipeline among the five types amt draws a conclusion that the most feasible scheme for packing is high-pressure pipeline.
