ABSTRACT
It is a widely adopted technique to use solution min-
ing salt caverns as underground energy storage, es-
pecially in those countries which have abundant salt
dooms such as United States, France and Germany.
By comparison with ground gas storage, those are
main advantages such as it can store a large amount
of oil and gas, so it has a wide adjustment range; be-
ing economical; durability, it can run for more than
30-50 years; security. Because of all the advantages
above, it becomes an important resource. In Germa-
ny, gas storage in salt cavern is a developed technol-
ogy with a history of about 50 years. At the end of
2007, there are 169 salt caverns operated as under-
ground gas storage and still many salt caverns gas
storages are under construction. All those have a
geometric volume about 15.3 billion cubic meters.
The storage volume is accounted for 19% of annual
consumption, approximately 69 days reserve. The
salt solution mining also belongs to mining and the
government attaches great importance to using and
protecting it. Salt cavern surveying technique leads
an advanced position in the world, it works as main
measure for government to supervise the companies
