Study on repairing technical parameters of irregular gas storage salt caverns

On-site sonar measurements reveal a high proportion of salt caverns with irregular contours, which poses a potential risk. Therefore, repairing these irregularities is crucial for the safe and economic operation of gas storage salt caverns. This paper proposes criteria for assessing the rationality of repairing irregular salt caverns, which can be used to judge the rationality of repair work before it is carried out. A procedure is proposed for determining the technical parameters by conducting an in-depth investigation of the correlation between these parameters and the factors influencing them. Methods are also proposed to quantitatively determine the range of certain parameters that affect technical parameters. By using the technical parameters determined by these methods, the repair efficiency can be significantly improved and the best repair effect can be obtained. The research findings have broad applicability and offer valuable guidance for future repair techniques of irregular salt caverns.
