The Dazhangtuo gas storage in Dagang Oilfield set a record for the longest "standby" operation of domestic gas storage reservoirs

As of October 8, China's first commercial underground gas storage - Dazhangtuo gas storage has achieved continuous safe production for 8,002 days, setting a record
since the construction and operation of domestic gas storage.

Dazhangtuo Gas Storage Reservoir, which belongs to Dagang Oilfield, was completed and put into operation in 2000, and is the first large-scale commercial underground gas storage in China, with multiple functions
such as seasonal peak regulation and emergency reserve.
After 22 cycles of injection and production tasks, the gas storage has produced a total of 9.
493 billion cubic meters of gas and 10.
165 billion cubic meters of gas, efficiently completing the tasks of natural gas peak regulation and emergency supply assurance, and delivering a steady stream of clean energy
to Beijing and surrounding areas.

In order to ensure safe and stable operation, Dagang Oilfield Gas Storage Group has always adhered to the policy of "safety first, prevention first, and comprehensive management" for many years, established the concept of "people-oriented, safe development", strictly implemented the safety production responsibility system for all employees, improved the safety system system, ensured safe production input and basic guarantee, promoted the construction of risk prevention and control system, innovatively summarized and used the "SRAD" method of gas storage safety physical examination and the "6815" workflow, and comprehensively strengthened the fine operation of gas storage injection and production.
Comprehensive supervision and management of equipment preventive maintenance and safety to improve emergency response capabilities
.
Through regular monthly safety meetings, thematic analysis meetings in key areas and other activities, we constantly build management consensus and improve management level
.

Since the beginning of this year, Dagang Oilfield has closely followed the themes of "System Construction Year" and "Gas Storage In-depth Assessment and Improvement", improved the standardization process, deepened the standardized operation, and continued to strengthen the operation management
of grassroots shift stations and contractors.
At present, it has organized 13 safety inspections such as "grasping teams, controlling the scene, ensuring safety" and "four not two straights", continuously promoting hidden danger investigation and governance, continuously improving the level of on-site risk management and control, and successfully completing the task
of ensuring natural gas supply during major events such as the National "Two Sessions", the Beijing Winter Olympics and the Winter Paralympics.

Up to now, the current round of gas injection in the 11 underground gas storage reservoirs belonging to Dagang Oilfield has exceeded 2.
057 billion cubic meters, 99.
1% of the overall gas injection plan has been completed, and more than
90% of the gas production preparation work has been completed.
The gas production of the Dagang Oilfield Gas Storage Group is expected to exceed 2.
3 billion cubic meters in the winter of 2022, which will provide a strong guarantee
for the demand for clean energy in Beijing and other surrounding areas.
