摘要
在天然气市场消费量快速增长、国内"三大四中"勘探开发格局逐步形成、陕西连续七年成为全国最大产气省份的背景下,我国天然气产量、消费重心变化明显。当前我国天然气供应呈现出"国产气为主,进口气为辅"的局面,天然气消费市场集中在环渤海、长三角和西南地区,2017年三地合计占当年全国天然气消费量的50%以上。运用重心理论,研究2006年至今我国天然气供需重心的分布位置和迁移路径。研究结果表明,我国天然气供需重心空间分布格局明显不同,供需重心都在向东南方向移动,但不存在交叉或重合,供需不均衡性在2014年后有加大趋势。建议在大力推进天然气产供储销体系的基础上,着力加快上游各方面建设,保障气源供应安全;加强基础设施建设,通过建设天然气支干线和联络线、LNG接收站解决供需两侧在空间上的矛盾,通过建设地下储气库等储气调峰设施解决时间上的矛盾;促进天然气回归其"商品属性",推进中西部地区天然气市场繁荣发展。
With the rapid growth of natural gas consumption in domestic market,the gradual formation of the exploration and development pattern of three large gas producing areas and four medium-sized gas producing areas in China,and the fact that Shaanxi Province has become the largest gas-producing province in the country for seven consecutive years from 2011 to 2017,China′s natural gas production and consumption gravity centers have changed significantly.At present,the supply and demand of natural gas in China presents a situation of relying mainly on domestic gas supplemented by imported gas,and the natural gas consumption market is concentrated in the Bohai Rim,Yangtze River Delta and Southwest China.In 2017,the total natural gas consumption of these three areas accounted for more than 50% of the national consumption.The theory of gravity center was introduced into the study on the distribution position and migration path of China ′s natural gas supply and demand gravity centers since 2006.The results show that the spatial distribution patterns of China′ s natural gas supply and demand gravity centers are obviously different,both the supply and demand gravity centers are moving towards the southeast,but there is no crossover or overlap,and the imbalance between supply and demand has presented a growing trend since 2014.On the basis of vigorously promoting the production,supply,storage and marketing system of natural gas,it is recommended to speed up the construction upstream to ensure the security of gas supply,strengthen the infrastructure construction to resolve the contradiction between natural gas supply and demand in space by building natural gas branch lines and tie lines and LNG receiving stations and to resolve the contradiction in time by building underground gas stor-ages,and promote the return of natural gas to its commodity attributes to promote the prosperity and develop-ment of the natural gas market in Midwest China.
