On April 6, the gas storage operation of the Xiangguosi gas storage in the Southwest Oil and Gas Field Company of PetroChina began on the 6th. At this point, the 23 gas storages of PetroChina have started gas injection operations in full, preparing for the supply of natural gas in winter and spring. According to reports, the Xiangguosi gas storage is the largest gas storage capacity in China. In 2018, PetroChina plans to inject 8.6 billion cubic meters of underground gas storage, of which Xiangguosi gas storage plan plans to inject 1.72 billion cubic meters of gas, creating conditions for this year's peak gas production of 1.65 billion cubic meters. Ma Xinhua, general manager of PetroChina Southwest Oil and Gas Field Branch, said that in 2000, China's natural gas consumption was 24.5 billion cubic meters, and by 2017 it reached 230 billion cubic meters, with an average annual growth of more than 10%. In the future, China's clean energy development strategy will be further promoted. Experts predict that by 2020, the apparent consumption of natural gas will reach 320 billion cubic meters, reaching 550 billion cubic meters in 2030, and the proportion of natural gas in primary energy will reach more than 10%. "The demand for natural gas is large in winter, and the demand in other seasons is small. It is the basic market law. If the production, supply, transportation and sales cannot be coordinated, there will be a passive situation of winter 'gas shortage' and off-season 'desolation'." CNOOC Research Institute Xu Jiangfeng, a senior engineer in the comprehensive planning of the Planning and Research Institute, told the China News Service that the development of the natural gas industry has driven huge demand for gas storage. The underground gas storage has become an important infrastructure for the country's strategic reserves and safe and stable gas supply. At present, there are 25 underground gas storages in China, including 23 of them, with a gas storage capacity of 40 billion cubic meters and a peaking capacity of more than 10 billion cubic meters, accounting for 98% of the domestic gas storage peaking capacity, which has promoted domestic The transformation from peaking of gas transmission to peaking of underground gas storage.
