Geological conditions of salt cavern gas storage in China are characterized by dominantly layered layers with a high content insoluble mudstone. After the water leaching layer, large amount sediment accumulates at bottom cavity. During injection process, only clean brine above can be expelled, leaving layer 2–5 m and pore space sediment. To increase capacity, it is urgent to explore secondary d...

In response to the localized corrosion generated by underground casing, which seriously affects safe operation of salt cavern compressed air storage, we used commercial finite element software, ANSYS, propose a partial model applicable casings with pitting and strip corrosion. The results show that depth casing is closely related fracture collapse pressure. As increases, its effect on pressure ...

The cryostats of the ATLAS LAr calorimeter system are installed in the ATLAS cavern since several years. Following this, an effort to install and commission the front-end and back-end read-out electronics as well as the timing, trigger and control electronics (infrastructure, crates, and boards) has been ongoing and is finished now, in time for the cavern closure. Following cautious procedures ...

Aiming at the acoustic attenuation in salt-cavern environment, this paper established a theoretical relationship of ultrasonic gas storage, based on wave equation propagating non-ideal medium, and considering specific environment analyzes how wall roughness storage affects attenuation. The results show that inner has an effect surface is solid-liquid interface, where change medium will affect w...

This article presents an estimation of the temperature decrease in vicinity a salt cavern due to its leaching. The one-dimensional radially symmetry models were considered and described. initial rock massif was assumed as 50 ∘C leaching water varied seasonally from 6 20 ∘C. A significant influence season process, beginning on final distribution found. model takes into account: convection coeffi...
