On April 12, Sinopec’s Jiangsu Oilfield launched the construction project for the Zhujiadun gas storage facility. The project is designed with a storage capacity of 662 million cubic meters and a working gas volume of 330 million cubic meters. Once in operation, it is expected to have a maximum daily peak-shaving capacity of 4.1 million cubic meters, sufficient to meet the gas needs of 8.2 million households per day. This will further enhance the region’s capacity for seasonal peak-shaving and emergency gas reserves in the Yangtze River Delta area, ensuring adequate gas supply there. The Zhujiadun gas storage facility is located in Yandong Town, Tinghu District, Yancheng City, Jiangsu Province. The main project is based on the Zhujiadun gas reservoir in the Jiangsu Oilfield. Studies have shown that the cap rock and faults surrounding the Zhujiadun gas reservoir possess good sealing properties, which provide favorable conditions for building an underground gas storage facility. It is expected that once the Zhujiadun gas storage facility is completed, it will be able to be connected to existing gas pipelines through interconnection lines, thereby enabling seasonal peak-shaving and emergency gas supply services for Yancheng, Jiangsu Province, and the Yangtze River Delta region. Why build new gas storage facilities? Natural gas is a natural fuel with a high calorific value, as well as an important raw material for organic chemical manufacturing. As a clean energy source, natural gas is gaining increasing popularity, with its share in the energy mix continuing to rise. With the continuous discovery and exploitation of natural gas resources in our country, its applications are becoming increasingly widespread. However, due to factors such as the annual and seasonal peak-valley differences between the gas supply area and the user areas, the imbalance between supply and demand is becoming increasingly prominent. It is at this time that the role of the gas storage facility becomes apparent. What is a gas reservoir? Gas storage facilities are known as underground \"natural gas banks\"; they are fundamental energy infrastructure that serve functions such as seasonal peak shaving, emergency gas supply in case of accidents, and **energy strategic reserves. As the share of natural gas in China’s energy consumption structure continues to increase, contradictions such as the disparities between supply and demand as well as seasonal variations in natural gas usage are becoming increasingly apparent. Gas storage facilities can serve as a means of \"storing\" gas when there is a surplus in the natural gas market, and can be used to \"release\" that gas when there is a shortage during the winter heating season, thereby enabling the regulation of natural gas supply. The location selection for gas storage facilities is highly demanding; it must meet criteria related to safety and reliability, technical feasibility, and economic rationality. The facilities need to be able to accept gas, store it, and extract it, while also being located away from cities, residents, and buildings. Additionally, they must be cost-effective. Currently, gas storage facilities include four types: oil and gas fields, salt caves, aquifers, and mine pits. In China, oil and gas fields are primarily used as gas storage facilities, that is, depleted oil and gas fields are converted into such storage sites. To accelerate the construction of essential natural gas infrastructure, ensure the implementation of projects beneficial to people’s livelihoods, and promote local economic development, the National Energy Administration issued the “Implementation Plan for Building National Gas Storage Capacity”. The Zhujiadun Gas Storage Facility is included in this plan. Sinopec has included the Zhujiadun gas storage facility in the key construction projects of the 14th Five-Year Plan. It is expected that once the Zhujiadun gas storage facility is completed, it will be able to be connected to existing gas pipelines through interconnection lines, thereby enabling seasonal peak-shaving and emergency gas supply services for Yancheng, Jiangsu Province, and the Yangtze River Delta region. In the design of gas storage reservoirs, taking into account the characteristic of single sand bodies in these gas reservoirs, a deployment scheme that combines horizontal wells with conventional wells is adopted to fully leverage the advantage of horizontal wells in terms of high capacity for gas intake and output ； In terms of information technology development, an intelligent gas storage facility construction management model based on \"fully digital design and full-life-cycle management\" is adopted, with the goal of creating high-quality projects for Sinopec.
