Recently, a large-scale cold wave has affected many regions in China. On November 8, the gas storage group of Dagang Oilfield officially produced gas. Banzhongbeiku 3-3, Ku 3-18H, Ban 808/828 Ku 5-3, and Ku 5-5 were the first to start production. , Officially transporting natural gas to Beijing, Tianjin, and Hebei to face the cold wave.
As the regional regulated gas source with the largest working gas volume and the fastest effect in the Beijing-Tianjin-Hebei region, the Dagang Oilfield Gas Storage Group is mainly responsible for the functions of natural gas regional peak shaving, emergency gas supply, and strategic reserve. So far, underground gas storages have been built9 There are two gas storages under construction, and the underground wells can be used for gas extraction within 2 hours to reach the central city of Beijing. Among them, Dazhangtuo gas storage is known as "China's first gas storage." Since its commissioning, this gas storage has been operating safely and stably for 7,669 days. In the past 21 years, the cumulative gas injection and production volume of the storage group has ranked first in the country.
In order to better cope with the peak period of guaranteed supply, Dagang Oilfield optimized production increase measures and scientifically improved peak shaving capabilities. The overall gas injection cycle this year has been shortened by nearly 25 days year-on-year. The Bannan gas storage under the jurisdiction of the reservoir group has comprehensively improved its emergency peak shaving capacity. The entire reservoir group is expected to exceed the historical extreme in peak gas production this winter and next spring, laying a solid foundation for the continued stable and safe heating of the Beijing-Tianjin-Hebei region. At present, 16 gas wells have been opened in this group of reservoirs, which can meet the gas demand of more than 50 million households in the Beijing-Tianjin-Hebei region every day.
To meet the needs of the situation, the Dagang Oilfield Gas Storage Group will also add new "members". The two compressors of the Lvjuhe Gas Storage under construction have been installed, and important ground facilities have begun to take shape and will be added to the supply guarantee next year. queue.
