In light of the first underground gas storage engineering in China, the principles of underground gas storage caverns with water curtain are presented.

Control of water seepage in caven”was one of the most important works in the construction procedure of the undersea gas storage cavern.

At present,the exploration of such new technologies as transportation and storage of solid-state natural gas et al on hydrates have developed quickly,but the applications in these fields are all barried by some factors,such as low density of gas storage,slow rate of formation and long induction period.

N gasholder and flexible seal gasholder in blast furnace gas storage.

Discussion is made on the technological problems in CNG fueling station, including metering, compression and dehydration, gas storage and high pressure pipeline.

Experimental investigation on methane storage in hydrate form;

Micellar surfactant solutions were found to increase gas hydrate formation rate and storage capacity.

Study and application of tightness testing technology for salt cavern gas storage;

Design method for geometry of dissolution cavity of salt gas storage considering the stability;

Numerical simulation research on long-term stability of gas storage in Jintan Salt Mine;

Investigation on optimized gas recovery velocity of natural gas storage in salt rock layer by numerical simulation;

Underground natural gas storage (UGS) can be categorized into 4 types, including depleted oil and gas reservoir, aquifer, salt cavern and mined cavern.

Salt rock has very low penetrability and good creep behavior, and can ensure the leak tightness of the natural gas storage.
