Look at the ten years of development of chemical equipment and praise the prosperity of China. Replies and prizes are welcomed for discussion----------------------------------------------On December 7, 2022, the Nanbao 1-29 gas storage constructed by Jidong Oilfield began to supply natural gas, marking that China's first offshore gas storage officially entered the first round of gas supply period. 　　It is reported that the Nanpu 1-29 gas storage is located on the Nanpu No. 2 artificial island in the Jidong Oilfield. It is China's first offshore gas storage converted from an oil reservoir. Following the principle of "fewer wells and high efficiency" in gas storage construction, the gas storage is designed with an effective storage capacity of 1.814 billion cubic meters and a working gas capacity of 1.052 billion cubic meters. Up to now, Nanbao 1-29 gas storage has injected a total of 177 million cubic meters of gas, with a working gas capacity of 150 million cubic meters, and a daily gas supply of 400,000 cubic meters. In order to improve the speed of expansion and production of the first offshore oil reservoir converted gas storage, Jidong Oilfield carried out dynamic tracking evaluation, optimization of injection and production parameters, and high-pressure nitrogen-assisted pressure reduction and injection. This effectively alleviated the gas injection situation of "strong at one point and weak at the other". The daily gas injection volume can reach up to 1.5 million cubic meters, laying a solid foundation for stable gas production. 　　At the same time, in order to ensure safe and stable gas supply this winter and next spring, the oilfield has made preparations in advance for the transition from the gas injection period to the gas production period, dynamically adjusted the gas injection and production operation plan, and carefully formulated gas production operation arrangements. Carry out comprehensive risk investigation on the gas production process system ； Implement winter prevention and insulation work in advance, debug heating furnaces, electric heaters and other production support equipment, ensure the safe and stable operation of the gas production process during the peak shaving period, and actively implement ground construction support measures, combine existing electric heaters to provide heat loads, strengthen the identification of on-site facilities and operating activities, carry out risk identification of gas production operations, etc., to meet the peak peak shaving capacity of 400,000 cubic meters/day of gas supply production capacity. 　　It is reported that during the "14th Five-Year Plan" period, Jidong Oilfield will build 6 gas storages including Nanpu 1-29, Baogu 2, Nanpu 1-5, and Nanpu No. 2 buried hill. Once completed and put into use, the Jidong Oilfield gas storage group will become the gas storage center of North China, effectively improving the natural gas peak-shaving and supply capacity in the Beijing-Tianjin-Hebei region. * * Energy security and promoting regional economic development in the Beijing-Tianjin-Hebei region play an important role.
