Research on maintenance and application of data management system for salt cavern

With the growing demand for energy of China, oil and gas storage safety will directly influence the development of Chinese economy, The use of salt cavern storage of oil and gas because of its unique advantages has become an important way for oil and gas storage, which has shown a good application effect in many countries. China is abundant in underground rock salt resources and is provided with geological conditions of basic construction of salt cavern storage. In order to exploit salt cavern for oil and gas, in the construction and management process of salt cavern, people must performed shape measurements on the salt cavern, and then analyzed the measuring data processing. In this paper, by the German SOCON company salt cavern surveying data as the research object, in-depth analysis of the record format salt cavern surveying data, using C# language programming to achieve the salt loading data, establishing salt cavern data application system, and realizing three-dimensional model of salt cavern exhibition, and also put forward a method to calculate the volume of the cave. To improve the security of the salt cavern gas storage, pave the way for the further study of salt cavern gas storage optimal shape.
