On July 31, the cumulative gas injection volume of the gas storage group of the North China oilfield exceeded 15 billion cubic meters, demonstrating the role of North China in ensuring natural gas supply. At present, the gas storage of Huabei Oilfield is conducting a new round of gas injection smoothly, and the number of gas injection Wells opened daily has reached the highest level in the same period of the past year.

In recent years, Huabei Oilfield has made great efforts to build the country's heavy "gas", taking advantage of its proximity to China's main natural gas consumption area, dense surrounding natural gas main pipe network, and many underground depleted oil and gas reservoirs, and vigorously promoting the construction of underground gas storage peak balancing center, which has played an important role in ensuring energy security. The gas storage group of North China Oilfield, which consists of Suqiao gas storage, Jing 58 gas storage and Wen 23 gas storage, adheres to the idea of "operation and construction". While successfully completing multiple rounds of injection and production tasks, it continues to carry out the evaluation and construction of new storage, the expansion and production of old storage, and the construction of ground supporting projects. The overall storage capacity, one-day injection and production capacity, and periodic peak load capacity have been improved year by year. During the period of supply protection last winter and spring, the daily gas production of the gas storage group in North China oilfield maintained a high operation for 31 consecutive days, and the volume of natural gas injection and production both exceeded the 2 billion cubic meters mark, and the working gas capacity of the storage group and the daily peak load balancing capacity both doubled in 5 years. Since the first gas storage was put into operation, the gas storage cluster of Huabei Oilfield has provided energy security for the Beijing-Tianjin-Hebei region for 15 consecutive years.
