中国地下储气库的发展驱动力

随着国内天然气需求的高速增长,地下储气库的需求也将不断增长,预计到2020年国内天然气需求量将达到4500亿立方米,对外依存度也将达到50%,同时按照储气库工作气量在天然气消费中所占比例,储气库建设规模也应至少达到450亿立方米以上。因此,分析了国内天然气市场现状以及国内储气库的现状,得出了地下储气库需求增长的驱动力：①天然气的大量进口,国内的开采量的提升以及各种非常规天然气的开发对储存的要求。②国内天然气消费量的高速增长以及天然气用气高峰期的调峰需求。③因为对外依存度高,为了应对因政治等问题产生的风险,储气库的战略储备能力显得格外重要。④国内地理因素和地质因素为大规模建设储气库提供了有利条件。

Motives for china underground gas storage

With the rapid development of domestic natural gas demand,the underground gas storage requirements will also be increasing,to 2020 domestic gas demand is expected to reach 450 billion cubic meters,external dependency will also reached 50%,at the same time,according to the working gas storage volume proportion in gas consumption,gas storage construction scale should be at least 45 billion cubic meters.Therefore,the analysis of the current situation of the domestic natural gas market as well as the status quo of domestic gas storage,it is concluded that the driving force of the underground gas storage demand growth：1.The natural gas of a large number of imports,domestic production of ascension as well as a variety of unconventional gas development requirement for storage.2.The rapid growth of the domestic consumption of natural gas and natural gas peak shaving of gas peak demand.3.Because external dependency,in response to the risk,because of the political issues such as strategic reserves of gas storage capacity is very important.4.The geographical and geological factors for domestic large-scale construction of gas storage provides favorable conditions.
