[Abstract]:The geological conditions of salt caverns in China are characterized by stratified distribution, many intercalations and great differences in burial depth. It is very important for the long-term stability and safe operation of salt caverns to control the formation of cavities with multi-intercalated salt caverns. The simulation and morphological control test equipment of salt cavities are developed successfully, which provides an advanced test method for indoor simulation and determination of the optimal salt cavity making process and shape control parameters. The device is designed and manufactured according to the principle of similarity. It consists of a test device frame, a multi-field coupling simulation system, a injection-production cycle system, a injection-production dynamic parameter measurement and control system and a salt cavity shape dynamic data acquisition system. The main structure of the test device is modular design; the multi-field coupling simulation system can simulate the ground and earth stress; the injection-production cycle system can simulate the injection and production water and the control oil cushion; the injection-production dynamic parameter measurement and control system can realize the inner and outer pipe height, The probe height and angle are controlled, and the dynamic data acquisition system of salt cavity shape can realize visual recording and real time measurement of the formation process. The experimental device can be used to visualize the influence of different construction technology and parameters on the process of salt cavern formation and the shape development of multi-intercalated salt rock under the condition of multi-field coupling. Through the cavity simulation test of different size salt core specimens, combined with the prediction of cavity development and the program of oil injection estimation, it is proved that the apparatus can simulate the visualization process of multi-intercalated salt cavities. The parameters of salt cavern construction and shape control can be used in field engineering.
