The Jidong Nanbao 1-29 gas storage is located about 20 kilometers northwest of Caofeidian in Nanbao Outer Bank, Tangshan City, Hebei Province. The joint oil and gas reservoir of this project includes the Nanbao 1-29 gas reservoir, the Nanbao 1-29 gas cap oil reservoir and the Nanbao 109 fault block gas reservoir. The capacity is 18.14×108 cubic meters and the working gas volume is 10.52×108 cubic meters. It is positioned as a seasonal peak-shaving gas storage. The gas source mainly comes from Tangshan LNG and Xintian LNG. The target market is mainly the three provinces and cities of Beijing, Tianjin and Hebei. Since the start of gas injection in the Hebei Nanbu No. 1 gas storage and Baogu 2 gas storage on April 29, 2021, as of May 24, 2023, the cumulative gas injection volume has exceeded 300 million cubic meters. The gas storage ground includes a collection station, a well site, two-way gas transmission pipelines and supporting stations. The centralized injection station was renovated and expanded in Nanbao Union Station, and a new set of 1100×104 cubic meters per day dew point control device, 700×104 cubic meters per day gas injection device and supporting auxiliary and public engineering facilities were built. On November 4, 2023, the Jidong Project of the Seventh Engineering Branch held a groundbreaking ceremony for the Jidong Nanbao No. 1 gas storage ground project. As a large-scale key project in Jidong Oilfield, this project marks that energy infrastructure construction has entered a new development model. Since the beginning of winter in 2023, China's first offshore gas storage - Nanbao No. 1 gas storage of Jidong Oilfield has started gas production, with a daily gas production capacity of 500,000 cubic meters, effectively improving the natural gas peak shaving and supply capacity in the Beijing-Tianjin-Hebei region, and ensuring the supply of natural gas. * * Energy security plays an important role in promoting regional economic development in the Beijing-Tianjin-Hebei region.
