Research on Dynamic Evaluation Technology of Multi-period Injection-Production Technology in Gas Storage

For gas storage multi-cycle injection and production process dynamic evaluation technology, mainly including gas storage geomechanical test analysis, injection and production well completion process research, gas storage capacity and injection and production layer gas analysis, the numerical simulation of aquifer gas storage effect, the influence of gas storage on condensate gas reservoir rocks and fluids, etc. In addition, the analysis of cavity creation and injection and mining technology of deep salt hole gas storage, the simulation calculation study of the dynamic injection and mining process of salt hole gas storage, and the determination of the operating pressure limit and the cavity shape detection in the process of injection and mining operation were completed. Finally, innovative puts forward a kind of intelligent gas storage multi-cycle injection-mining process dynamic evaluation system, the artificial intelligence technology applied to underground gas storage injection-mining process dynamic evaluation system, can realize gas storage efficient repeated injection supplement inventory, complete from underground gas storage facilities in high speed repeated injection and gas ability optimization and intelligent operation management, to build safe and efficient, accurate monitoring, intelligent decision-making comprehensive wisdom of gas storage more cycle dynamic evaluation system and supporting system has far-reaching significance.
