摘要
论述了天然气系统的储气要求,提出按储气目的进行分类,天然气储气可分为战略性储气(简称储备)、常规储气(运行调峰、应急储气)、商业性储气。为衡量战略性储备水平,笔者建议采用基本储备水平与安全储备水平两个指标。给出了基本储备水平公式、应急储气计算方法。提出内陆城市天然气公司应用LNG气源的方式——协议交换。建议我国天然气系统采取三级储存模式,提出了一系列关于天然气储存和储备的概念和观点。
The gas storage requirement for natural gas system is discussed. The classification of gas storage according to purposes is proposed. The natural gas storage can be divided into strategic storage （hereafter referred to as simply reserve） , conventional storage （operational peak shaving and emergency storage） and commercial storage, in order to estimate the level of strategic storage, two indexes for basic reserve level and safety reserve level are recommended to be used. The formula for basic reserve level and the calculation method of emergency storage are given. The application mode of LNG source by inland natural gas hompanies, namely the protocol exchange is presented. It is recommended that threestage storage mode is used for the natural gas system in China. A series of concepts and points of view concerning natural gas storage and reserve are put forward.
