The present invention relates to a salt rock butted-well water solution cavity body flow field and concentration field stimulation experiment method. The method comprises the steps of: constructing abutted-well water solution cavity flow field and concentration field stimulation experiment device; processing a salt rock test piece, and preparing brine; connecting an experiment system; performingexperiment steps; and processing experiment data. The method provided by the invention presents complex characteristics of the actual flow field, researches a key effect of the flow of the solution cavity fluid on the extension of the cavity shape, achieves combination of engineering practice and a fluid theory, explores the general characteristics of the complex flow field of the butted-well solution cavity and obtains optimal production parameters in a technical process, so that the cavity construction cycle time is shortened, more economic benefits are created, requirements of practical application are satisfied.
