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

The underground salt rocks in China are mostly layered salt beds, and some of the salt beds are deeply buried, which makes the construction of salt cavern gas storages face more technical challenges in the process of drilling and completion [3]
Summary
Underground gas storage is a key link in the natural gas industry chain and an important part of the pipeline transportation system. It adjusts the balance of supply and demand in the daily natural gas supply, but it plays an irreplaceable role in an emergency situation in which an accident occurs. Underground gas storage has played a pivotal role in the natural gas storage system of various countries and has formed a relatively complete operating mechanism.
