This invention belongs to the field of salt cavern gas storage engineering, specifically disclosing a method for brine treatment, gas storage, and cavity expansion in salt caverns. The method integrates brine absorption, gas storage, and expansion in two salt caverns, A and B. Through the formation of a hydraulic fracturing network and pressure drive by the brine, rapid in-situ absorption of large volumes of brine can be achieved on an engineering scale, significantly improving brine absorption efficiency. Furthermore, hydraulic fracturing modifies the cavity of salt cavern A, increasing the brine storage space in the reservoir, allowing for more efficient and larger-volume brine discharge from salt cavern B, expanding its usable space, and increasing the construction volume of salt cavern B as a compressed air storage facility. In addition, the method reduces or even eliminates the energy consumption and facility investment required for large-scale surface brine concentration and evaporation or long-distance transportation, significantly reducing processing costs.
