我国天然气地下储气库布局建议

在我国天然气进口依存度持续高位的形势下,构建合理的天然气地下储气库布局对于保障国家能源安全、促进我国经济长效发展有着重要的现实意义。在调研国外天然气储备发达国家地下储气库布局的基础上,分析我国不同地区天然气消费与地下储气库建设资源特点,对我国天然气地下储气库布局提出建议。结果表明：我国西北部天然气供给多元化而消费量较少,且油气型储气库建库资源丰富,地下储气库建设应以战略储备为第一目的。我国中西部和西南部地区天然气供给充足,具备大型气藏型储气库建设条件,且邻近我国中部、东部经济发达地区,储气库建设应兼顾战略需求和调峰需求,建成中国天然气储备“枢纽区”;环渤海地区和东北地区季节调峰需求大,且具备一定的油型储气库建库资源,应以满足调峰需求为目的开展油气型储气库建设;中南地区建立油气型储气库资源不足,但具备建立盐穴型和含水型储气库的条件;东南沿海地区基本建立地下储气库的条件相对不足,应以LNG建设为天然气储备能力提升的主要手段。

Suggestions on the layout of underground gas storage in China

Under the situation of the high dependence on the import of natural gas in China, it is of great practical significance to construct a reasonable underground natural gas storage layout for ensuring the national energy security and promoting the long-term economic development of China. Based on the investigation of the layout of underground gas storage in foreign countries with developed gas reserves, analyzes the characteristics of natural gas consumption and underground gas storage construction resources in different regions of China, and puts forward some suggestions on the layout of underground gas storage in China. The results show that the supply of natural gas in Northwest China is diversified but the consumption is small, and the construction of oil and gas storage is rich in resources. The construction of underground gas storage should take strategic reserve as the first purpose. China"s central and Western and southwest regions have sufficient natural gas supply, and have the conditions for the construction of large-scale gas reservoir type gas storage, and are close to the economically developed regions in central and eastern China. The construction of gas storage should take into account the strategic demand and peak shaving demand, and build China"s natural gas reserve "hub area"; the Bohai Rim region and northeast region have large seasonal peak shaving demand, and have a certain amount of oil type gas storage capital In order to meet the demand of peak shaving, the construction of oil and gas storage should be carried out; the resources of oil and gas storage in central and southern China are insufficient, but the conditions of salt cavern and water-containing gas storage are available; the conditions of underground gas storage in southeast coastal areas are relatively insufficient, so LNG construction should be the main means to improve the natural gas storage capacity.
