Technical development status quo and inspiration of typical gas storages in North America

Underground gas storage plays an important role in natural gas markets. It is irreplaceable in peak shaving and gas supply safety assurance. In recent years, the construction of domestic gas storages has been developed fast, but still remained at the initial stage while compared with North America. This paper concludes the experiences in design, construction, operation and management of foreign gas storages based on detailed investigation and researches on status quo, operation and management and technical features of gas storages in North America. It is proposed as follows for the development of domestic gas storages, refer to the routine operation and management modes of gas storages in North America, strengthen the researches on drilling technologies, take the large-diameter horizontal wells and elevate injection-production ability of single well and highlight material innovation researches
