The effects of operating pressure and ground stress on the seepage parameters (permeability and porosity) of surrounding rock and stability and tightness of salt cavern have been investigated, and a method is proposed for safe operating pressure…
To address flow-induced vibration failure problems of leaching tubing in salt cavern underground gas storage, a nonlinear flow-induced vibration model of the leaching tubing in salt cavern gas storage was established using the energy method, element…
Salt cavern gas storage is an important strategic method to shave the fluctuation of supply- demand of natural gas in China. However, due to low grades of salt beds, there remains lots of insoluble sediments accounting for 1/3 up to 2/3 of the…
to balance the intermittent of renewable power, large-scale energy storage in underground salt caverns can be utilized. And the construction and safety evaluations for these caverns become necessary. Aimed at the bedded salt rocks for energy storage,…
With the rapid development of the global economy and the adjustment of energy structure, the demand for underground salt cavern gas storage is particularly urgent. The technology of double-well cavity creation with small well spacing is a relatively…
Compressed air energy storage (CAES) is a promising energy conversion storage technology and underground salt caverns are recognized as the appropriate storage places for it. The reduction of air during the withdrawal periods leads to the surrounding…
Using nitrogen as the blanket for the construction of a gas storage salt cavern by the solution mining under gas (SMUG) method has many advantages, such as improved safety, enhanced environmental protection and better economy. A critical issue for…
To reduce effects from anthropogenically induced climate change renewable energy systems are being implemented at an accelerated rate, the UKs wind capacity alone is set to more than double by 2030. However, the intermittency associated with these…
Underground salt caverns provide appropriate space for storing natural gas. However, salt caverns have to be constructed in bedded salt formations in China. The traditional construction method of salt cavern encounters serious problems in such…
To fully utilize the abandoned salt cavern resources and to increase the total amount of the fossil energy reserve of China, reconstructing some of these salt caverns for underground gas storage (UGS) or strategic petroleum reserve (SPR) would be an…
With the rapid development of the global economy and the adjustment of energy structure, the demand for underground salt cavern gas storage is particularly urgent. The technology of double-well cavity creation with small well spacing is a relatively…
The current status and development trend of natural gas pipelines and storage in China is summarized briefly. With the development of economy, the natural gas demand in China increases rapidly
