The article presents the results of a numerical simulation deformation-stress state in rock mass around salt cavern which is part CAES installation (Compressed Air Energy Storage). model based on parameters Huntorf power plant installation. influence temperature and salt-creep speed stability storage was determined basis three different stress criteria effort points at time intervals. analysis ...

Underground TWH (Two-well-horizontal) salt caverns are an ideal storage medium for large-scale energy storage, having large usable volumes and high construction efficiency. Different tubing/oil-blanket lifting techniques relate to different solution mining rates help define cavern geometries based on the previous experience of SWV (Single-well-vertical)-cavern construction. In this study, we pr...

Evaluating the possibility to store CO 2 in salt mines is made complex because of lack necessary data and different mechanisms that act on time scales. This analysis can be using traditional methods geographical survey, lab experiments digital simulations. Storing needs done a stable geological area. The cavity must thoroughly analysed for dimensions, depth, permeability porosity. Based studies...

In the early construction of cavern leaching in salt gas storages, inner tubing is often blocked, frequently leading to bending deformation phenomenon strings, which can result out-of-control cavity shapes. It difficult monitor stress, vibration, and morphological changes tube during a cavity. There are few research results this field at home abroad, they limited only preliminary explorations m...

With the rapid development of national economy and increasing demand for energy, acceleration natural gas storage strategies, underground has become more important in China’s oil consumption energy safety. Underground salt cavern many advantages is very suitable peak shaving?However, most rocks China are layered beds, some beds deeply buried. This article introduces history deep technical chall...

Abstract Jianghan Oilfield salt cavern gas storage is characterized by depth, high temperature and pressure. At present, the main problem of that in process cavitation, frequent bending deformation at end cavitation tubing string leads to difficulty operating string, which extends period affects production storage. The was counted, causes were analyzed from aspects layer geological characterist...
