The main solution mining method of gas storage in salt cavern is positive cycle in China. The solution mining speed is low which need from four years to five years to build a cavern with the volume of 200000 cubic meters. The method of solution mining is single. It is difficult to adapt to the rapid development of domestic underground gas storage. Many kinds of solution mining methods are required to be studied in order to increase the solution mining speed. By numerical calculation and field application, the process and advantages & disadvantages of all sorts of solution mining modes are described, the reasean to increase solution mining speed are analyzed such as reverse circulation, large hole, double well, double strings and so on. Research shows that the main solution mining modes of gas storage in salt cavern in the future are reverse circulation, large hole, double well and double strings, which can increase solution mining speed effectively. There are some shortcomings and difficulties of solution mining with large hole cavity and double well and double strings. Many key technologies need to be studied. Cementing is difficult for large hole method, it is difficult to control cavity for double well method, production casing is vulnerable to brine corrosion for double well method. The solution mining of reverse circulation is relatively mature with cavity controlling and cushion detection, which can improve solution mining peed effectively by more than 20% and can advance the construction process of gas storage in china.
